My issue is resolved, either by:
https://www.reddit.com/r/Fedora/comments/pddl09/problems_with_suspend_function/har1zwc/
so:
sudo systemctl enable nvidia-suspend.service
sudo systemctl enable nvidia-resume.service
sudo systemctl enable nvidia-hibernate.service
if they were not enabled.
Then I reinstall the evdi driver that is included in the displaylink driver, since I had a kernel update.
The driver seemed to work, but I did:
- run intalll
- reboot & rmmod evdi ( otherwise installer complains it’s loaded )
- run installer again and reboot
The installer in my case is the one for ubuntu.
I also needed to set as mentioned here: Fedora 34 KDE unable to suspend after nvidia driver update
and edited /usr/lib/modprobe.d/nvidia-power-management.conf by replacing the “1” by a “0” and it looks like it’s working!
You may have another issue with the USB-c dock.
Check dmesg output for hints on the exact cause if the above did not help, it will hopefully point you further.
It may be xhci related.
Please post you findings, good luck!
