Bug Description

[Impact]

Upgrades to 18.04 can pull in only libnvidia-gl-390 which provides libegl-vendor and libglx-vendor, thus fulfilling the dependency for libegl1/libglx0. This will cause issues on machines which don't use the nvidia proprietary driver. To fix this libegl1/libglx0 should depend on libegl-mesa0/libglx-mesa0 to make sure that the Mesa stack gets used by default.

[Test case]

Test upgrading from 16.04/17.10 to 18.04, check that it installs the Mesa libraries.

[Regression potential]

None, these get already installed if 18.04 image is used.

[Original Description]
After upgrading to Ubuntu 18.04, my desktop uses software rendering, no matter what I do.
As far as I know, all necessary packages are installed.
Formerly I had oibaf installed, but suspecting that this may cause the problem, I removed it with ppa-purge. It didn't help.

First I noticed the problem when I tried to play HD videos.
It was fine before the upgrade. My hardware is capable for 3D acceleration, as it worked on 17.10.

I don't know why, but apport attached wrong (outdate) Xorg logs to my report. Probably it's a gdm feature that it puts logs elsewhere instead of the usual /var/log/Xorg.0.log.

The actual logs made by my X11 server are located here:
/var/lib/gdm3/.local/share/xorg/Xorg.0.log
/home/megabrutal/.local/share/xorg/Xorg.1.log

I attach the correct logfiles.

This looks relevant. Xorg is saying:

[ 2402.232] (II) AIGLX: Screen 0 is not DRI2 capable
[ 2402.232] (EE) AIGLX: reverting to software rendering

Are you able to log into Wayland sessions?

How can I switch to Wayland? Contrary to the articles those tell otherwise, I have no option to select it on the login screen.

Anyway, 17.10 worked fine with Wayland, so switching back to Wayland might probably help.

I used to use it, but uninstalled it with ppa-purge, but this problem is present regardless of oibaf is installed.

The problem is that lib{e,}gl1 let lib{egl,glx}-vendor to fulfil the dependency, which apparently will pull the nvidia versions in some cases. The alternative depends needs to be dropped.

Please be more verbose regarding the SRU verification, at least specifying the version number of the packages tested and what overall testing has been performed. Updates are frequently 'stuck' in -proposed because of this information lacking.
