Hello, in power options i have Screen Blank option set to 5 minutes, 90% of the times when I try to wake it up the screen just stays black and i have to hardware reset. I am running the lts kernel and the nvidia-dkms video driver. I am not sure why this is happening but it makes me think its due to nvidia and wayland.
here is part of the dmsg
I should boilerplate this:
point 10, also ensure the nVidia services are enbled.
Create:
## File: /etc/modprobe.d/nvidia-power-management.conf
options nvidia NVreg_PreserveVideoMemoryAllocations=1 NVreg_TemporaryFilePath=/var/tmp
options nvidia_drm modeset=1
options nvidia_drm fbdev=1
options nvidia NVreg_EnableGpuFirmware=0
run sudo reinstall-kernels and reboot, then test.
i do not have reinstall-kernels, it seems its part of kernel-install-for-dracut.
:: kernel-install-for-dracut-1.11-1 and mkinitcpio-39.2-3 are in conflict. Remove mkinitcpio? [y/N]
If you don’t have it, then your system is not using dracut but mkinitcpio. Don’t remove mkinitcpio.
If you need to rebuild your kernel images, you can do:
sudo mkinitcpio -P
allright I tried what you suggested but I am still experiencing black screens and keep loosing all my work consttanly. Every time i leave the pc for 10 minutes when I come back i just get back to a black screen and have to hardware reset.
The command I gave you just rebuilds your kernel images as was suggested above to do so by @xircon. Your issue lies somewhere else. I am not using nvidia so I can not help.
I have been messing around with kernel versions and such but I still cant figure out why I have this blackscreens. If anyone has any troubleshooting suggestions please let me know.
