I try it again, this error has nothing to do with bug #1861609. In 2020 I was running Xubuntu 20.04 and Virtualbox 6.1. This error only occurs in Xubuntu 23.10 and it does not occur in the development edition of Xubuntu 24.04. I will add journalctl -b as attachment and indeed it is related to vboxguest. nov 08 13:15:51 VM-Xubuntu-2310 kernel: vboxguest: loading out-of-tree module taints kernel. nov 08 13:15:51 VM-Xubuntu-2310 kernel: vboxguest: module verification failed: signature and/or required key missing - tainting kernel?field.comment= ** Attachment added: "journal.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2040037/+attachment/5717296/+files/journal.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/2040037 Title: Xorg crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/2040037/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
