I couldn't upload the crash file _usr_lib_xorg_Xorg.0.crash, because
ubuntu-bug wants to open a web browser, which is obviously not possible
when X11 is not available.
Through an "ssh -Y" session, I got a window with the following error message :
Sorry, Ubuntu 18.10 has experienced an internal error.
If you notice further problems, try restarting the computer.
And in the terminal :
QPainter::begin: Paint device returned engine == 0, type: 2
QPainter::end: Painter not active, aborted
I was able to run an XTerm window through the same connection.
I've launched apport-bug without arguments, and it uploaded all
information it could in bug #1803123
apport-bug was nice enough to show an URL to work with uploaded data. It
would be nice if ubuntu-bug could do the same when uploading a crash
file !

Title:
X.org crashes after upgrade to 18.10
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
After the upgrade from 18.04 to 18.10, SDDM fails to start. This happens with
kernel 4.18.0-10 and 4.15.0-36 (it was the chance to discover grub-reboot)
See SDDM crash file attached.
The machine is a virtual machine, and PCI devices use virtio-pci
driver for example.
I looked into /var/log/Xorg.0.log and found many error messages, the first
one being :
(EE) open /dev/dri/card0: No such file or directory
See Xorg log file and crash file attached.
Then I looked at the output of 'lspci -vvnn' and it seems that no kernel
driver manages the VGA Controller.
See output of 'lspci -vvnn' attached
According to the following message, the missing kernel driver may be :
bochs-drm or virtio-vga
