Hello I recently installed fedora kde plasma desktop on a seperate disk while dual booting windows 11. When i awake from sleep mode, I get a black screen on my monitor with red light in cpu led indicator on my motherboard. The only way of fixing this is by hard rebooting by pressing the power button. How do I fix this?
That sounds like a suspend/resume issue.
Try this editing GRUB /etc/default/grub.
Add this mem_sleep_default=deep to the GRUB_CMDLINE_LINUX line.
Then update GRUB:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot and test sleep again.
Also remember, it’s helpful to include what GPU/CPU you’re running. NVIDIA? AMD?
NO!
Please always provide the proper commands
Since about fedora release 32 that command should be
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
Changing the file you indicated will break all future kernel updates and require a different recovery process.
