The three added lines to the /etc/environment file did not make a difference. I tried both "Ubuntu" and "Ubuntu on Xorg" logins. I was connected through a KVM to the monitor however, because I am sharing a monitor, mouse and keyboard with other machines. So, I plugged a monitor in directly (as well as a separate keyboard and mouse) and now I am able to log in normally using either the "Ubuntu" or "Ubuntu on Xorg" logins. I removed the three lines from the environment file again and login still works. So it looks like 22.04 just does not like my KVM switch.
The KVM switch is a CKLau (CKLau-64HUA-UK). On Tue, May 3, 2022 at 10:30 AM Daniel van Vugt <[email protected]> wrote: > Thanks for the log.
