[solved] XFCE4.20 not waking screen from idle sleep

[shimbob]

I'm battling an irritating issue, my monitor won't come back to life after it goes to sleep from being idle.

Despite turning off the display power management within the XFCE Power Manager, my screen will go to sleep when I walk away, computer itself remains awake. When I come back and try to wake it (mouse movement or key press) the screen turns on, cycles through the inputs, tells me there's no signal, and goes back to sleep. Attempting to wake it again does not result in the screen waking up a second time.

Because I'm old school, I've enabled ctrl-alt-backspace to zap xorg and zapping xorg revives the screen with the display manager (SLIM) waiting for a login. The computer does not crash.

Also when the screen is black, I can ctrl-alt-f1 to a console and the monitor turns on, but returning to X brings back the blank screen and the monitor turns off again. No error message in either Xorg log or dmesg.

I think I've even tried xset s off and xset -dpms and the screen still went to sleep. Maybe I need to poke around the bios some more to see if there's some setting.

One more thing I tried is to delete .config/xfce4, which resulted in waking working again, but only for about a day before it starts misbehaving again.

Setup: XFCE 4.20, amdgpu with an rx 6700 xt, xanmod-kernel 6.12.12 but also happens under 6.11.12, xscreensaver not installed

An additional data point. If I tell slim to not autologin and the computer is left at the login screen when left idle, the screen will turn on properly after shutting off from idle. This suggests an XFCE issue.

I'm going to try leaving it idle after returning to slim after using XFCE to see if it carries over.

It did not carry over. This is really starting to look like an XFCE4 issue.

After seeing this post, I investigated the Display->Advanced tab. There were no profiles listed so I created one. Then walked away to let the computer idle and came back to a screen that turned back on properly! Deleted the profile and let it idle again and the screen wont wake once again. Definitely an upstream XFCE4.20 issue for sure.

Thank you for coming to my Gentoo Rubber Duck Talk.

Thank you for providing an answer and not be deterred by the lack of answers. Sometimes the problems are to individual.

Ya, issues don't get solved if we all keep to ourselves.

Issue is known upstream, XFCE 4.20.1 has a fix.
