Resolution control

[1Guardian]

Hello, not sure if this is even related to breath in any way, but I was wondering if anyone had talked about/experienced issues with changing resolutions in breath? By default, the resolution is correct, but I wanted to step the resolution down for certain games. I used a xandr command to add a resolution successfully, but whenever it is set, the resolution looks like it applies, and then immediately reverts back to the original resolution. Once again, not sure that this is related to breath in any way, but was just curious if it is or if I should be looking in a different place for advice.

Hardware: Acer spin 713-2w
OS: Ubuntu 22.04

I would suggest using adding the xrandr command to your .xinitrc or something of the like. Xrandr always reverts to default after any system suspend, which tends to be the system's native resolution. Hope that helps👍

@1Guardian In your original summary you mentioned you use Ubuntu. Have you tried setting the resolution in Settings/Display Settings? Ubuntu and Gnome distributions in general use wayland, which does not like forced xorg/xrandr commands, as we can clearly see with the immediate override, and the xrandr output is not as it should be. I would try setting the res. via settings and see if that works. On another note, if you downscaling simply to play games at higher refresh rates, it is better and more optimal to downscale with in-game settings, as any game takes full control of your compositor and in general it is better to do so this way.

@timmypidashev It does the same thing through the settings 'displays' page. It flashes, seems like it set it to the new resolution for about half a second and then reverts to the original resolution. Also I'm using X11, so wayland is not an issue. And I am using in-game resolution settings for the games that have them, but I have some indie games I want to run which have no in-game settings for resolution; they just go into full screen and use whatever resolution is applied by the system at the time.

@timmypidashev You made me wonder if it would work in wayland after mentioning it, and upon logging back in with wayland instead of X11, running the xandr commands actually worked and stayed. So it has something to do with X11, which is annoying.

Interesting, I'm not sure anymore what angle to even touch this problem with anymore. I'll get back to you if I think of something, sorry.

@timmypidashev no problem, I'm in the same boat as you. And thanks for all your help!
