Bug Description

Users who have manually configured an xorg.conf file with nvidia enabled as a driver will be surprised to have disabled on upgrade to a new release of Ubuntu and won't have a graphical display.

Test Case
If you don't have a system with nvidia hardware to upgrade this is a bit convoluted but still works.

1) Run do-release-upgrade (use -d if upgrading to disco)
2) Cancel the upgrade
3) Create an /etc/X11/xorg.conf file with a Device section listed in the original description using the nvidia driver.
4) cd to /tmp/ubuntu-release-upgrader-$TEMPNAME
5) run ./$target-release-name --frontend DistUpgradeViewText
6) Observe the Driver line is commented out of xorg.conf

When testing the release-upgrader from -proposed you'll need to use the -p switch to get the right tarball. Additionally, you'll want to add a step 4.5 where you modify xorg_fix_proprietary.py so nvidia defaults to True instead of False (line 106) this'll simulate the nvidia driver being loaded.

Regression Potential
This just changes how xorg_fix_proprietary check for nvidia being in use and it only affects people who have an /etc/X11/xorg.conf so the impact of a regression is rather small. Additionally, the logic used to determine if nvidia in use is the same logic used in the apport package hook for all xorg packages so is well tested.

Original Description
I upgraded my system from 17.10 to 18.04 Bionic Beaver via do-release-upgrade.
After the installation had finished, Xorg wouldn't start. I later found out that this was because the installation routine had commented out the nvidia display driver I used in the xorg.conf:

Section "Device"
    Identifier "nvidia"
# Driver "nvidia"
    BusID "PCI:10@0:0:0"
    Option "ConstrainCursor" "off"

As the installtion routine backuped my xorg.conf I could verify that the line hadn't been commented out before upgrading. Removing the "#" solved the problem.

The file the release upgrader is looking for doesn't exist in the current nvidia packages or exists in another location.

Could you provide your /var/log/dist-upgrade/main.log file from the upgrade to Ubuntu 18.04? Thanks in advance.

Hi Brian, I attach the log file.

Looking at the log file we can see the following:

2018-05-21 09:55:56,514 DEBUG nvidiaUpdate()
2018-05-21 09:55:58,109 INFO no old nvidia driver installed, installing no new

Then looking at DistUpgradeCache from ubuntu-release-upgrader there is this:

 540 # get new detection module and use the modalises files
 541 # from within the release-upgrader
 542 nv = NvidiaDetection(obsolete="./ubuntu-drivers-obsolete.pkgs")
 543 #nv = NvidiaDetection()
 544 # check if a binary driver is installed now
 545 for oldDriver in nv.oldPackages:
 546 if oldDriver in self and self[oldDriver].is_installed:
 547 self.mark_remove(oldDriver, "old nvidia driver")
 548 break
 549 else:
 550 logging.info("no old nvidia driver installed, installing no new")
 551 return False

Unfortunately, the dist-upgrader tarball doesn't actually have "ubuntu-drivers-obsolete.pkgs" in it so nv.oldPackages is always empty and no old nvidia driver will be detected.

And it looks like this is something I removed last year, here's the changelog entry.

  * build-tarball.sh: Stop updating ubuntu-drivers-obsolete.pkgs since it
    isn't needed any more see Launchpad bug 1682291 for details.

The xorg apport package hook checks /proc/modules for the presence of nvidia which seems better than looking multiple places for an nvidia .so file, so let's convert xorg_fix_proprietary.py to check for that.
