Question for @rockedge

I notice booting up that I get a message when loading modules that /usr/lib/ is not a valid directory to mount the modules (I think that's the directory it's saying.)

Let me reboot and check that.

Everything seems to work. My temperature sensor isn't working on this machine (showing steady 25degress), but it works on another machine in Spectr, and this machine's temp displays in Airedale.

I don't know if it's related to that message, or if that message is a problem or not.

EDIT:

Yes, I just rebooted and saw that it's trying to load modules to /usr/lib/modules, but the directory doesn't exist.

what does the terminal display? for 1 line and after for 2

Never a good sign......I will give it a look and try to figure out what's going on.....(with Marvin Gaye playing in the background.....)

The system seems to be running alright despite the error?

Yes, I'm not noticing any hiccups or missing components, except the polybar temperature thing which only happens on this one machine so far, not on others.

It's just something I noticed while booting today, and it goes by fast. It may be that it's been that way since day one, which would have been a good while now.

You guys are probably using Beta-3 as the base.

or even better if you show me the path "/sys/class/hwmon/hwmon0/temp1_input"

all laptops are different and without seeing this I can’t know what to do

Temperature is hanging around 50 degrees C in the polybar now.

So @rockedge, Sofiya got my temp reading in the polybar, but I'm guessing that module message probably shouldn't be happening.

But like I say, I don't notice anything amiss hardware wise in all this time using KLV-Spectr-beta2.

Everything seems to work on all my machines that normally works per machine, there's always the odd wireless card that no puppies or KLV's seem to fire up.

It’s strange, of course, that it shows you incorrectly through “Thermal-zone”

If I actually understood what the definition of 'sysclass' is, I could offer some feedback, but these kinds of components and coding are very far above my head.

Of course I could learn, given enough time and motivation!

I'm pretty good at understanding general concepts like modules and drivers, but how they are loaded, called, and interact is a complete mystery to me.

This is a very old (15+ years) Dell Precision 4600, and from my experience these older Dell laptops run on the hot side (this one is not so bad) So I think temperature hardware and drivers might be more problematic with them. I'm only guessing from experience. The fans are always whirrring off and on using the two older Dells that I have.

My HP laptops tend to run much cooler.

The fan probably needs cleaning.

Possibly, but opening a laptop is something like doing HEART SURGERY!

I'm not bad with electronics in general, being a musician, but I hate the mechanical part. I tend to use the wrong tools and break things.

I bought this from a used computer shop about 4 years ago, and they installed a new hard drive and such, so I assumed they cleaned it, but who knows?

@Sofiya and @rockedge here's what I have so far for a key-binding cheat sheet. I still have to comb through the default key bindings and test to see what still works. There are a couple things still missing. But I'm getting buggy at this hour.

How do you like the format?

I better attach it, as it doesn't seem to fit in the code window.

Good, I will finish it up.

I think I should add a key binding that opens a window displaying this list. Then include a script in Startup to display a welcome message with a reference to the keystrokes to open the Key Binding List:

Maybe: Control+MOD1+k

Probably need to define a program first, which would be a small script that opens the file in a text viewer.

I will also modify and save the list without the commands included, just to tidy it up. It might make more sense to list the ACTION first, so the list would show ACTION/KEY/TYPE

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

Post by rockedge »

I am testing a KLV-Spectr-RT that is using @fredx181 's audio setup using the 20pipewire-spectr.sfs and installation steps to have audio running through pipewire.

It seems to work but the polybar volume shows only the icon but no percentage value displayed:

The indicator works when the pulseaudio daemon is running and not when using pipewire

@Sofiya

I've added these lines to spectrwm.conf:

Code: Select all

 program[pavucontrol]	  = pavucontrol
 bind[pavucontrol]             = MOD+Shift+p
 

right click on the volume icon opens Pavucontrol

This icon works through a script

Here's a complete, concise, user-friendly key-binding list, which contains the pavucontrol keybinding (I like having that option, thanks for the right-click option @Sofiya )
