Hi there.
Just 2 days ago, I installed CachyOS on my system. So far everything has been working out rather fine and I’ve been enjoying the experience, but today I noticed that when I resume/wake from suspend/sleep I get only a black screen, but only in X11. Resume from suspend works fine in Wayland, the login screen appears as intended for me to get back in my session.
My desktop environment is KDE Plasma.
I tried to look for solutions or people with similar issues, but people usually have the reverse problem. That is, they have problems resuming from suspend in Wayland, while it works fine in X11.
I’m using the defaults of everything, so I have the default cachyos kernel, and the latest Nvidia driver (565.77). My GPU is RTX 3060 Ti.
Not sure if this is relevant, but I can see the cursor when I resume my computer from suspend. Behind it, however, there is only a black screen. Only way for me to get out is by physically pressing the power off button so my computer turns off and then reboot. I even tried getting into a tty, but that doesn’t work out either.
This is a desktop computer, and everything works fine in Wayland.
Before CachyOS, I had openSUSE Tumbleweed installed in this computer. Also kernel version 6.12 and KDE Plasma, but the Nvidia driver there is a bit older, they use the current production branch driver 550. Resume from suspend worked fine there in both X11 and Wayland.
I’m a bit at a loss here. If you need any more info or logs please let me know and I will provide them.
