Description Michael Brown 2021-05-08 20:06:49 CEST

This is reoccurring issue that seems to get fixed in the next kernel update, then it seems to break in another update later on, so it's hard to keep track of when the issue is fixed for a long time. It seems to be related to certain Nvidia video cards because some of the systems I have are not affected sometimes. So this might be a combination of the type of video card and Xorg, not really sure how to tell the difference. Basically, as of writing this, kernel 5.10.33 is not working on my system, but if I boot into kernel 5.10.27, everything is working fine again.

Xorg version - 1.20.11

Video Card Details:
GM107 [GeForce GTX 750 Ti]

Other System where kernel-desktop-5.10.33-1.mga7 is working fine with Xorg
Video Card Details:
GT218 [GeForce 8400 GS Rev. 3]

Sum up:

Kernel 5.10.33-1.mga7 + Xorg version - 1.20.11 + Nvidia GM107 [GeForce GTX 750 Ti] not working? But 5.10.27 seems OK?

There was a Nvidia driver update released for Mageia 7 as Bug https://bugs.mageia.org/show_bug.cgi?id=28854

Do you use nvidia nonfree driver?
Could you share us the output of 'dkms status' command?

Comment 4 Michael Brown 2021-05-10 17:06:47 CEST

Yes, using the nvidia nonfree driver. (64 bit)

Comment 5 Thomas Backlund 2021-05-10 17:18:47 CEST

Check if there is a log message about mis-matched nvidia driver, or simply when booted into kernel-desktop-5.10.33-1.mga7 , do as root:

dracut -f

and reboot

does it work then ?

I looked through the Xorg log file and saw this:

Also, the "dracut -f" worked, I'm not booted into without any issues.

Thanks, so nos this is fixed?

Seems you get hit by Nvidia drivers + kernel update in same RPM transaction and initrd was not properly updated...

Note: on Mageia 8 and Cauldron, updating nvidia-current and kernel in same transaction is working OK.


Note 2: for inxi, this is a useful tool for bugsquad team to know about reporter system. You can install it with "urpmi inxi" even on Mageia 7.

Status: NEEDINFO => RESOLVED
Resolution: (none) => FIXED
