Boot the installed system, wait for Snappy unpacking/initialization/seeding (check from tty1 with `snap list`) 5. Install Ubuntu restricted extras with `sudo apt-get install ubuntu-restricted-extras` and reboot 6. Login to desktop session 7. Get crash of whole Xorg after login when of Ubuntu MATE Welcome window is starting to appear. Guest settings: choosing video acceleration disabled or 3d video acceleration does not change behavior. Increasing VRAM from default 16 Mb to 128 Mb (max for my machine) does not help either. VirtualBox versions tested: * 5.1.38-dfsg-0ubuntu1.16.04.3 (from multiverse) - crash, * 5.0.40 (from Oracle) - crash, * 5.1.38 (from Oracle) - crash, * 5.2.36 (from Oracle) - crash, * 6.0.16 (from Oracle) - crash, * 6.1.2 (from Oracle) - crash. --- Removing `ubuntu-mate-welcome` from autostart with `sudo rm /etc/xdg/autostart/ubuntu-mate-welcome-autostart.desktop` fixes the login issue. But direct launch of it with `ubuntu-mate-welcome` ends with another crash. -- 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/1796437 Title: X11 crashed when attempting to open Budgie and MATE Welcome Status in ubuntu-mate-meta package in Ubuntu: Confirmed Status in ubuntu-mate-welcome package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Won't Fix Bug description: Went to the menu button in upper left corner.
