I opened up https://bugs.launchpad.net/ubuntu/+source/xinit/+bug/1876119 which is a duplicate of this bug.
We are celebrating the fourth anniversary of this bug. Perhaps xinit should be removed from Ubuntu if it's not a maintained package anymore? This bug is still affecting me on latest 20.04 distribution. I have tried the following workarounds - Setuid root for /usr/bin/Xorg (or setgid) - Adding user to tty group - Logging in to tty1 with the same user I start the X session with - chmod 666 /dev/tty1 None of these work. The only option that works is installing xserver-xorg-legacy and configuring /etc/X11/Xwrapper.config as follows: allowed_users=anybody needs_root_rights=yes The only option ** Information type changed from Public to Public Security -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xinit in Ubuntu. https://bugs.launchpad.net/bugs/1562219 Title: Unprivileged xinit wont start in unallocated vt To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xinit/+bug/1562219/+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
