Using the apt available DKMS does not work But mounting the 6.1.16 virtual disc with Virtualbox runnable installer works (VBox_GAs_6.1.16)
After doing : sudo ./VBox_GAs_6.1.16.run and rebooting The display now works again in full screen properly. Working config is : - VirtualBox-6.1.16-140961-Win - Oracle_VM_VirtualBox_Extension_Pack-6.1.16 - Installed Guest Additions for 6.1.16 - kernel Linux asgard 5.8.0-34-generic #37~20.04.2-Ubuntu SMP Thu Dec 17 14:53:00 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910503 Title: latest kernel breaks display full sizing in virtualbox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1910503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
