Bug 135718

So you mean that the console logins should have lower priority than X
logins? So if someone logs out of X but is logged on console he/she
doesn't lose the ownership of the devices but if then someone else
logs in X he gets the ownership.

Easier change without necessary code changes would be to assign
ownership only on X logins, but then the user 1 would lose the
ownership immediately after logging out of X. This is easily
achievable by changing console.perms by making the console class equal
to xconsole class - this of course cannot be made default as many
users depend on the current behaviour.

What would I need to do to make the console equal to the xconsole
class? I can try it and if it works, this request can be closed

Replace:
<console>=tty[0-9][0-9]* vc/[0-9][0-9]* :[0-9]\.[0-9] :[0-9]
with:
<console>=:[0-9]\.[0-9] :[0-9]

Then the console logins (non X) won't affect the permissions and
ownership of device nodes.

This is probably impossible to do right. You can make various
manipulations with console.perms file on workstations with concurrent
multiuser access but it wouldn't be right to unnecesarily complicate
the setup for normal desktops.
