I am facing the same bug. VirtualBox Graphical User Interface Version 6.1.34 r150636 (Qt5.6.2) Copyright © 2022 Oracle Corporation and/or its affiliates. All rights reserved with Ubuntu 20.04.2.0 LTS on Windows 10 Pro, Version 10.0.18362 Build 18362
I reloaded the VirtualBox Guest Additions which came as an ISO file with Version 6.1.34. I did download the same version from another mirror, but I have not installed that separately. Should we consider updating Ubuntu beyond this supposedly stable version of Ubuntu 20.04? Assuming that a prior version of VirtualBox worked with Ubuntu 20.04, the bug is most likely on the VirtualBox side. I just hate the idea of a rollback at this point. I should have created a restore point before updating VirtualBox, so I could rollback. Shutting down VirtualBox and restarting it did not fix the problem for me either. If I go to VirtualBox with the display setting VMSVGA, I just get a black screen on my DELL Latitude E6420. VBoxVGA is my typical mode, but it keeps popping up the event error. I can change the display setting in the VBoxVGA more. I think I have had unstable results with VBoxSVGA mode, but I might try that again. Maybe, I need to up the display memory to 128MB for that to work; I have display memory set to 96MB right now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873922 Title: 20.04 not compatible with virtualbox-guest-x11: Fails changing display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1873922/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
