Puppy Linux Discussion Forum

I have never setup a multi-monitor system, so have no exerience. EasyOS, like some other pups, has Zarfy for configuring multiple monitors.

Someone recently reported that while watching a youtube video in the browser, the screen saver kicked in periodically and the screen went black.

There is an app (Caffeine-ng) that sits in the tray, that you can use to toggle screensaving on/off and it also detects if any app running full-screen and automatically disables the screensaver.

The pup_event mechanism that is in all pups, has some code that detects if certain apps, such as mplayer, are running and automatically disables the screensaver. However, that was implemented in the pups a very long time ago, and I don't know if woof-CE built pups still have it. Anyway, it isn't appropriate for the browser, which isn't a dedicated video player.

What I want to do is build upon that original pup_event code and add detection of any app running full-screen.
I found this very useful info:

But, I would like full-screen detection to work on multiple monitors. So, first questions for those with multiple monitor experience:

Do you run all monitors with the same resolution?

If not, does a utility like 'xwininfo -root' return the resolution of each monitor?

I personally don't always use the same resolution for all monitors depending in what i'm doing, however I may switch mode of a monitor it suits me. so it can be the same having a different window on each screen.
My new Acer NUC (amd5700) / twin wacom 4K system does have the capability, but usually one is set for 4k and the other either 1920x~ (2k) or 2560x~(2.5k);
My intel NUC has both a 3k and a 1920x~ monitor which I usually use in their 'default' modes;
My HP graphics notepad 3000x2000 has a number of screens available and also normally uses the monitors defaults. it has no problem with different sizes unless I want to run both in graphics mode;
My Acer Touch has 1920x~ by default with the second screen set as a 2.5K;
My various Dell systems usually DO run 1920x~ on both screens, as much for convienance as anything else.

There's also the thing to think of with multiple monitors where one og them may be used in lanscape mode and the other portrait mode.

A major part of the problem, always seems to be if the application you want to use can handle 2 or more screens internally rather than the hardware, as long as you have the ram to work with different resolutions(,2x4k screens i've found want 16gb in basic mode and 32gb in full graphics), a lot of hardware can't deal with this, even if you want to do so.

Unfortunately i'm totally re-aranging my office to suit my new gear this week, and only my internet workstation is connected at the moment so I can't run xwininfo on a multi-screen system until next week. I'll try then
and let you know the result.
