KLV-Spectr-RT with full real-time kernel 6.1.38-rt13c

[Sofiya]

I cleaned up this hotkey splash screen quite a bit, corrected some typos, added all the key bindings that are in my 4.4 system, and made a few variations of colors, all with DejaVu Mono bold 9. Attached is an actual .gz with the files, including the keybinding-config

One more note, my keybinding to launch the splash screen ( MOD+MOD1+k) is configured in spectrwm.conf to look for /root/Startup/Spectr-hotkeys.sh

If you don't want the splash in startup but still want to launch it with MOD+MOD1+k, just change the path to your location.

@geo_c You are great, the main thing is to push you in the right direction You measured the dimensions so clearly that the config looks like a glove.

I actually have a good eyeball for centered text.

Except why now after I finish it up do I notice that I have MOD1 for Alt in the first section, and every entry after says ALT?

That's the kind of stuff that keeps me from writing actual code.

what you wrote is what is displayed

[geo_c]

what you wrote is what is displayed

Yes, it works. I like to see consistency though. I think in the list "Alt "is easier to pick out. Whereas using "Super" for MOD just clutters the screen, "Alt" for MOD1 is easier to read.

EDIT: I see I misunderstood you! Now I get, it's a computer, it does what I type into it!

When I get time I'm going to clean that up and make it consistent, maybe even add a background image.

[geo_c]

I think I've got this Hotkey splash screen pretty clear looking now. Changed all the MOD1 references to ALT. Made a few little text adjustments to make it more user friendly, like adding top lines with "Reopen This Window = MOD+ALT+k" and "Drag This Window = MOD+MouseButtonL" to minimize frustration for anyone trying it the first time. I'd like to tweak the colors, but these seem to work for now.

Include in the zip are two folders, one set with fontsize=9, the other fontsize=12 for those with high resolution monitors. 12 works on this machine very well.

Really nice!

I am trying to keep up putting all of the advancements and new polish into one rootfs! Good is I can make one KLV-spectr_rootfs that can just be swapped into a KLV-Spectr-beta3 (for example) and KLV-Spectr-RT.

the beta3 is uploaded to the usual place and sports a Void Linux kernel 6.5.7_1 and the RT version can fly with full real time kernels 6.1.38-rt13 or 6.5.2-rt8. As usual the kernels can be swapped into any KLV variant.

@Sofiya Now for the part where we stuff all of it into a PLUG and perhaps a script to automate an assembly of KLV-Spectr-xxxx......

I will upload a decent KLV-Spectr-RT ISO later today (planned but who really knows?)........

[wiak]

Is it cold where you are right now rockedge? Wooly hat.

[rockedge]

@wiak It's starting to get chilly......and waiting to until at least Oct 31 to turn on the furnace which is fueled with oil. We are awaiting a Nor'Easter storm coming in from the North Atlantic and even though it's sunny right now....(nice in the sun actually) it's a bit chilly on my older bones to sit in front of the machines and in the typical Hamburg harbor style a wool blue hat makes it seem not that bad........and does promote the willingness to make some good hot coffee in the kitchen...........

plus I should be outside raking leaves though I did clear the house roof yesterday......but I gotta combine the new tech into one good PLUG.....

Glad I could contribute something! If we'd like to put some information in a welcome splash, I could work on that also. It might be something we could use on other KL variants.

EDIT It occurs to me that I didn't include a typical light foreground, dark gray background colorscheme, I'll add one orr two of those to match most dark gtk themes.

[rockedge]

dark gray background colorscheme........

Here is me pondering how I'm going to make a selector mechanism for the different looks so it's easy for a user to choose which to use......

I did a bit of lighting to enhance the effect...

Also working with a script that I hope will help improve the audio volume display when using pipewire. which does not show the volume percentage value, just the percent sign.

Terminology: A node represents either a sink (output) or source (input).

Options:
  --autosync | --no-autosync
        Whether to maintain same volume for all programs.
        Default: \"$AUTOSYNC\"
  --color-muted <rrggbb>
        Color in which to format when muted.
        Pass empty string to disable.
        Default: \"${COLOR_MUTED:4:-1}\"
  --notifications | --no-notifications
        Whether to show notifications when changing nodes.
        Default: \"$NOTIFICATIONS\"
  --osd | --no-osd
        Whether to display KDE's OSD message.
        Default: \"$OSD\"
  --icon-muted <icon>
        Icon to use when muted.
        Default: none
  --icon-node <icon>
        Icon to use for node.
        Default: none
  --format <string>
        Use a format string to control the output.
        Remember to pass this argument wrapped in single quotes (\`'\`) instead
        of double quotes (\`\"\`) to avoid your shell from evaluating the
        variables early.
        Available variables:
        * \$VOL_ICON
        * \$VOL_LEVEL
        * \$ICON_NODE
        * \$NODE_NICKNAME
        * \$IS_MUTED (yes/no)
        Default: '$FORMAT'
  --icons-volume <icon>[,<icon>...]
        Icons for volume, from lower to higher.
        Default: none
  --node-type <node_type>
        Whether to consider PulseAudio sinks (output) or sources (input).
        All the operations of pulseaudio-control will apply to one of the two.
        Pass \`input\` for the sources, e.g. a microphone.
        Pass \`output\` for the sinks, e.g. speakers, headphones.
        Default: \"$NODE_TYPE\"
  --volume-max <int>
        Maximum volume to which to allow increasing.
        Default: \"$VOLUME_MAX\"
  --volume-step <int>
        Step size when inc/decrementing volume.
        Default: \"$VOLUME_STEP\"
  --node-blacklist <name>[,<name>...]
        Nodes to ignore when switching. You can use globs. Don't forget to
        quote the string when using globs, to avoid unwanted shell glob
        extension.
        Default: none
  --node-nicknames-from <prop>
        pactl property to use for node names, unless overridden by
        --node-nickname. Its possible values are listed under the 'Properties'
        key in the output of \`pactl list sinks\` and \`pactl list sources\`.
        Default: none
  --node-nickname <name>:<nick>
        Nickname to assign to given node name, taking priority over
        --node-nicknames-from. May be given multiple times, and 'name' is
        exactly as listed in the output of \`pactl list sinks short | cut -f2\`
        and \`pactl list sources short | cut -f2\`.
        Note that you can also specify a port name for the node with
        \`<name>/<port>\`.
        It is also possible to use glob matching to match node and port names.
        Exact matches are prioritized. Don't forget to quote the string when
        using globs, to avoid unwanted shell glob extension.
        Default: none
  --listen-timeout-secs
        The listen command updates the output as soon as it receives an event
        from PulseAudio. However, events are often accompanied by many other
        useless ones, which may result in unnecessary consecutive output
        updates. This script buffers the following events until a timeout is
        reached to avoid this scenario, which lessens the CPU load on events.
        However, this may result in noticeable latency when performing many
        actions quickly (e.g., updating the volume with the mouse wheel). You
        can specify what timeout to use to control the responsiveness, in
        seconds.
        Default: \"$LISTEN_TIMEOUT\"

Actions:
  help              display this message and exit
  output            print the PulseAudio status once
  listen            listen for changes in PulseAudio to automatically update
                    this script's output
  up, down          increase or decrease the default node's volume
  mute, unmute      mute or unmute the default node's audio
  togmute           switch between muted and unmuted
  next-node         switch to the next available node
  sync              synchronize all the output streams volume to be the same as
                    the current node's volume

dark gray background colorscheme........

Here is me pondering how I'm going to make a selector mechanism for the different looks so it's easy for a user to choose which to use......

Well, I don't know. First thought is just to include one of these basic dark splashes which will go with a light or dark theme.

Second thought is I could probably create a gxmessage chooser brought up by MOD+ALT+k, which could be annoying in the long run.

Or grep the gtk colors and automatically choose one of maybe 5 available splashes?

That pipewire display script looks ridiculously complicated.

I did a bit of lighting to enhance the effect...

Also working with a script that I hope will help improve the audio volume display when using pipewire. which does not show the volume percentage value, just the percent sign.

Usage: $0 [OPTION...] ACTION

Terminology: A node represents either a sink (output) or source (input).

Options:
  --autosync | --no-autosync
        Whether to maintain same volume for all programs.
        Default: \"$AUTOSYNC\"
  --color-muted <rrggbb>
        Color in which to format when muted.
        Pass empty string to disable.
        Default: \"${COLOR_MUTED:4:-1}\"
  --notifications | --no-notifications
        Whether to show notifications when changing nodes.
        Default: \"$NOTIFICATIONS\"
  --osd | --no-osd
        Whether to display KDE's OSD message.
        Default: \"$OSD\"
  --icon-muted <icon>
        Icon to use when muted.
        Default: none
  --icon-node <icon>
        Icon to use for node.
        Default: none
  --format <string>
        Use a format string to control the output.
        Remember to pass this argument wrapped in single quotes (\`'\`) instead
        of double quotes (\`\"\`) to avoid your shell from evaluating the
        variables early.
        Available variables:
        * \$VOL_ICON
        * \$VOL_LEVEL
        * \$ICON_NODE
        * \$NODE_NICKNAME
        * \$IS_MUTED (yes/no)
        Default: '$FORMAT'
  --icons-volume <icon>[,<icon>...]
        Icons for volume, from lower to higher.
        Default: none
  --node-type <node_type>
        Whether to consider PulseAudio sinks (output) or sources (input).
        All the operations of pulseaudio-control will apply to one of the two.
        Pass \`input\` for the sources, e.g. a microphone.
        Pass \`output\` for the sinks, e.g. speakers, headphones.
        Default: \"$NODE_TYPE\"
  --volume-max <int>
        Maximum volume to which to allow increasing.
        Default: \"$VOLUME_MAX\"
  --volume-step <int>
        Step size when inc/decrementing volume.
        Default: \"$VOLUME_STEP\"
  --node-blacklist <name>[,<name>...]
        Nodes to ignore when switching. You can use globs. Don't forget to
        quote the string when using globs, to avoid unwanted shell glob
        extension.
        Default: none
  --node-nicknames-from <prop>
        pactl property to use for node names, unless overridden by
        --node-nickname. Its possible values are listed under the 'Properties'
        key in the output of \`pactl list sinks\` and \`pactl list sources\`.
        Default: none
  --node-nickname <name>:<nick>
        Nickname to assign to given node name, taking priority over
        --node-nicknames-from. May be given multiple times, and 'name' is
        exactly as listed in the output of \`pactl list sinks short | cut -f2\`
        and \`pactl list sources short | cut -f2\`.
        Note that you can also specify a port name for the node with
        \`<name>/<port>\`.
        It is also possible to use glob matching to match node and port names.
        Exact matches are prioritized. Don't forget to quote the string when
        using globs, to avoid unwanted shell glob extension.
        Default: none
  --listen-timeout-secs
        The listen command updates the output as soon as it receives an event
        from PulseAudio. However, events are often accompanied by many other
        useless ones, which may result in unnecessary consecutive output
        updates. This script buffers the following events until a timeout is
        reached to avoid this scenario, which lessens the CPU load on events.
        However, this may result in noticeable latency when performing many
        actions quickly (e.g., updating the volume with the mouse wheel). You
        can specify what timeout to use to control the responsiveness, in
        seconds.
        Default: \"$LISTEN_TIMEOUT\"

Actions:
  help              display this message and exit
  output            print the PulseAudio status once
  listen            listen for changes in PulseAudio to automatically update
                    this script's output
  up, down          increase or decrease the default node's volume
  mute, unmute      mute or unmute the default node's audio
  togmute           switch between muted and unmuted
  next-node         switch to the next available node
  sync              synchronize all the output streams volume to be the same as
                    the current node's volume

Code: Select all

Management:
left click - mute sound
right click - Paucontrol
mouse wheel - adjusts volume

-----------------------------------------
should also work with Pulseaudio

Here is me pondering how I'm going to make a selector mechanism for the different looks so it's easy for a user to choose which to use......
my_photo-9-320px.jpg

Well I don't normally post photos of myself on the webbernet since the onslaught of AI scraping and all that... but I found it incredibly cool to know who I'm talking to. And who am I fooling anyway, it's all in a file in a black box somewhere...

So here's me contemplating why I'm tweaking OS's instead of practicing all the tunes I have to play Thursday night, which as you can tell I find humorous:

[geo_c]

Well, I don't know. First thought is just to include one of these basic dark splashes which will go with a light or dark theme.

Well actually what I could do is make a separate key binding to bring up a gxmessage chooser that overwrites the Spectr-hotkeys.sh with the new colorscheme. Like:

Code: Select all

program[keysplashcolor]  = /root/keysplash-color-chooser     
bind[keysplashcolor] = MOD+Control+k 

then the gxmessage would run a simple cp command like

Code: Select all

cp /root/my-applications/SpectrKeys/Spectr-hotkeys.sh-basicdark /root/Startup/Spectr-hotkeys.sh

When it comes to IT, I'm like the guy that fixes everything with duct tape and WD-40.

[fredx181]

Here's photo of me (I may not look as handsome as you guys, but that's of course because of the bad quality of the photo );
EDIT: Nice to see btw that the gtk3 splash has it's use

Glad I could contribute something! If we'd like to put some information in a welcome splash, I could work on that also. It might be something we could use on other KL variants

Yes, good thing about such utils are that they use little in the way of resources and, with slight modification sometimes, can easily be used in other KL variants. It has always been a bit like a LEGO build system factory and who doesn't enjoy building with LEGO simplicity?

Endless scope really. Gives users/builders lots of control/individual-power to customise on small or large scale. We end up with better and constantly improved distros therefore.

[rockedge]

@Sofiya I did copy all the latest into the rootfs.......I'll check the packages as well......odd...I copied Spectrwm-bar-polybar-v4.6.tar.gz into the rootfs before I squashed it......

Guess I'll have to try it again.....

[geo_c]

Still working in my PFI Install of beta two, with all of @Sofiya's v4.4 additions, I had installed OctoXbps as recommended. I normally use command line xbps, so I finally tried to launch OctoXbps from the menu, and got the message:

"You can not run OctoXbps with administrator's credentials."

Is there an easy solution for this? Should it be run as spot?

[geo_c]

try this Comment out line 761 , in line 769 write hwmon-path = /sys/class/hwmon/hwmon0/temp1_input

You know what? I installed all the 4.4 polybar files on my Dell Inspiron, much older than the Dell Precision that you helped troubleshoot the temperature tray config, and the Inspiron had the same issue. Temp reporting steady 25 degrees.

So I applied the same fix, only it didn't initially work and I changed "temp1_input" to "temp2_input" and the tray worked! I needed to be able to see the temp on that particular machine because I used to run jackalpup on it, which is a RT kernel and the thing would shutdown at the failsafe temp.

I have that one on a cooling pad now, and it does much better, hangs around 50-65 degrees.

So I think these older Dells do have a slightly different temperature monitor.

KLV-Spectrwm Dracula

[wiak]

I tried Spectr for the first time.

Problem with my machine - wouldn't boot with that kernel, but booted fine once I swapped in kernel/modules/vmlinuz from KLV-Swayland.

Looks good. A bit like Sway, though many of the chosen key combinations are different; trying to use same ones would be nice but problem then is that would be far from the upstream defaults, which I want to keep.

I had trouble with keybinds in Spectr though - some didn't seem to work the ways Mod+z said they would; for example 'minimize' and 'restore' (not in Spectr right now and can't remember the keys used but I think it was Mod+Alt+i which didn't seem to do anything. Probably I'm just not understanding correctly what it means and how to use it though.

yes @wiak , you are right about these keys, I also researched this and these combinations behave incorrectly.It’s not clear what is causing this behavior.

[rockedge]

@wiak thanks for testing out KLV-Spectr ! I am surprised the kernel 6.1.38-rt13 didn't start in your machine. The beta3 model has a Void Linux kernel that should be good but of course most any of the KLV kernels would work as well. Good to know though. Sway is also pretty good. Each tiling WM has it's strengths but I feel KLV-Spectr in RT mode or using another kernel, is going to be a good choice for speed, responsiveness and it's lightness in resource usage.

We'll need to hammer out the few bugs. I'm still not that familiar with any of the tiling WM's navigation completely yet.

@Sofiya, @geo_c perhaps we should have a spectrwm.conf that uses the default MOD1 and see if the commands work in the default configuration. Also I will again go over the rootfs to check for missing packages.

It's close to a solid release...........so the work on the launchpad continues.

Probably I'm just not understanding correctly what it means and how to use it though.

I fall into this category as well

What you have to watch with Spectr is window focus. MOD+ALT+i works for me. What it does is minimizes the focused window, so it should disappear from view. To restore, pressing MOD+Shift+i then brings up the stock dmenu on the bar and displays minimized windows for that workspace. Arrow keys page through them, then pressing ENTER will restore the window to it's previous state, so if it was floated and sized, it should come back the same.

So far all of my keybindings work well. But we should make sure that all our keybinding in spectrwm are consistent with each other. I'm working off a PFI install, which is why I included my keybinding config file with the splash scripts. Those need to be pasted carefully into spectrwm.conf for all of them to work. Of course I suppose different keyboard and hardware could be an issue.

EDIT and as I said, the bindings have all worked for me, there is one small annoyance though. When the splash screen is active, and I move it to a different workspace using MOD+Shift+[1=10], and then subsequently want to switch to workspaces using keys like MOD+right, MOD+[1-10], or MOD+up, nothing happens for a good 5-10 seconds. Then at some point the keys become available again. It's like spectr has a lag moving a splash to a new workspace. Clicking with the mouse will immediately cause the keys to be responsive again. So, that's the only mysterious bug I've noticed so far with the keys.

EDIT2 and it may be possible if using @Sofiya's modifications to the bar to allow for full screen video viewing (which I have not incorporated due to time issues and not really needing it) might have something to do with keybinds, as I believe some were changed, like restarting Spectrwm, etc... EDIT3 Also I believe the way the polybar and built in spectr bar interact was changed, and that seems like a likely culprit, in that when using the minimize/restore function, you might not be seeing the stock dmenu.

@Sofiya, @geo_c perhaps we should have a spectrwm.conf that uses the default MOD1 and see if the commands work in the default configuration. Also I will again go over the rootfs to check for missing packages.

Probably I'm just not understanding correctly what it means and how to use it though.

I fall into this category as well

now that you explained how it works, the test showed that it really works

amendment:
and yes, some of the keyboard shortcuts that @geo_c added are not in my configuration.for the reason that I am satisfied with the way I have

This function does not affect anything
