VirtualBox has version 6.1 (on Ubuntu MATE 18.04.6 amd64 host), using default VBoxSVGA driver which works well with Ubuntu MATE 21.10 with the same Xserver version as common package base.
Using VBoxVGA driver results with the same failure. Switching video driver to VMSVGA helps. ** Summary changed: - gdm3 shows only purple color screen in virtualbox + gdm3 shows only purple color screen in virtualbox with default VBoxVGA or VBoxSVGA video drivers ** Summary changed: - gdm3 shows only purple color screen in virtualbox with default VBoxVGA or VBoxSVGA video drivers + gdm3 shows only purple color screen in virtualbox with default VBoxSVGA or VBoxVGA video drivers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945704 Title: gdm3 shows only purple color screen in virtualbox with default VBoxSVGA or VBoxVGA video drivers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1945704/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
