I have a privileged Archlinux lxc container running under ubuntu 19.04 host.
I have GPU passthrough/sharring with the host. (cuda, nvidia gtx 1070)
I have recomplied gdm with the following flag
So that gdm will start in VT 8, which it did (until the upgrade to systemd)
The guest has full access to /dev/tty4 - /dev/tty9
After upgrading systemd to version 243.0:
gdm does run, but it does not spawn in any of the VTs including VT8
I am getting now the following new error in journalctl:
Sep 13 20:16:54 arch systemd: Failed to set devices.allow on /system.slice/systemd-logind.service: Operation not permitted
subsequently I am getting this error:
Sep 13 20:16:54 arch systemd-logind: Failed to pin reserved VT: Operation not permitted
Sep 13 20:16:54 arch systemd-logind: New seat seat0.
And then finally getting the following error
Sep 13 20:16:55 arch gdm-launch-environment]: pam_systemd(gdm-launch-environment:session): Failed to create session: Seat has no VTs but VT number not 0
I am able to run X11/Gnome (using startx, but when I do that I get a lot of keyring notification that I did not get before.
Is there a workaround to avoid the “Failed to set devices.allow…” It looks like some kind of permission issue that I might be able to fix in the config file of the guest. Any help will be appreciate.
Do I need to file a bug?
