Upgraded to Workstation 43: 2560x1080 resultions issues (X11->Wayland)

[netw0rk (Marian Stancik)]

Hi guys,

I have read that the X11 was completely replaced by Wayland technology.

I have recently upgraded to F43 Workstation, however, I cannot get my two LG UltraWide Monitors expecting 2560x1080 to work.

I have old Nvidia GeForce GTX 750 Ti which provided this resolution on F42. But on F43, I get only 1920x1080 (which sucks to look at big times!!!)

It is possible that the removal of X11 support collides with my NVidia and Drivers (up to date) to get the 2560x1080 resolution?

Thanks for any tips.

M.

KDE spin - Nvidia driver bug(?) in latest update

Hi all, I was wondering how to report a broken dependency(?) in the rpmfusion/xorg third party drivers for Nvidia The last kernel update now does not support 21:9 monitors. It has been working perfectly for the last 2-3 years, but broke on the latest update (updates weekly or twice a week.) Faultfinding and attempts to repair it are detailed here: Maximum now is 16:9 resolution, 1920 x 1080p . (As I’m on a deadline, I am just working with it now, knowing it will likely be resolved unless …

Possibly.
The newer driver may have issues with that older gpu. If using the nvidia driver and if it is necessary that you use the nvidia 470xx driver then almost certain since the older 470xx nvidia driver only supports X11 and does not support wayland properly.

You may have better results removing the nvidia driver and using nouveau instead, though I don’t have a clue how nouveau works with the ultra wide monitors.

@computersavvy

nouveau

Thank you @computersavvy for this tip. I will research on this option. Cause everything else I have tried by now fails..
