Please try running: apport-cli _usr_lib_xorg_Xorg.0.crash
and then copy and paste the link it (eventually) gives you into a web browser on a different machine. If for any reason that doesn't work then the next option is to look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1802950 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 https://www.redhat.com/archives/libvir-list/2015-August/msg00220.html # lsb_release -rd Description: Ubuntu 18.10 Release: 18.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1802950/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
