I've tried to follow that howto; but it should be set out of the box:

Status changed to 'Confirmed' because the bug affects multiple users.

This bug also appears in Arch linux 4.18.10 running gdm 3.30.1 on X11 (xorg server 1.20.1).

[Maybe also related](https://askubuntu.com/questions/1114350/ubuntu-18-04-1-freezes-when-connecting-to-a-second-screen)? I have added some syslog errors if that helps anyone solve the issue.

I get this error from the sessiom of GDM3:

gsd-color from user id 120 trys reading a private file of user id 1000. That seems wrong by design. It's a security fault.

The last comment of this bug report appears to describe what's happening:

https://bugzilla.redhat.com/show_bug.cgi?id=1641541

There are 2 Xorg processes running for some reason. One I'm logged into, and the other is on another VT. The one I'm logged into has my user id. The other one has uid gdm.

The Xorg with uid gdm has a child gsd-color process with the pid that matches the errant log message.

There is also a gsd-color process with my uid that is a child of systemd --user. I assume this happens when I logged in.

So this seems to be a bad byproduct of there being 2 Xorgs and gdms running. Why does this happen anyway?
