[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[quazgar (quazgar)]

Also happens from time to time (no update happening), but not reproducibly, on Kubuntu 18.04 LTS

[Roger Light (roger.light)]

I have just experienced this on Kubuntu 20.04. I have an nvidia card and apt just upgraded the nvidia drivers. I wonder if that is related. After the upgrade, blender refuses to start, stating that there is no supported graphics card so *something* has changed there.

[steve77 (funmaker-11)]

I just updated my NVIDIA driver on Kubuntu 20.04. I had to use a konsel and issue the rebbot command to bypass this problem. Could this be a problem with NVIDIA drivers.

[steve77 (funmaker-11)]

reboot command.

[Scarlett Gately Moore (scarlettmoore)]

This bug is very old, if it is still an issue please update the bug with info from a supported release.
