Description John Covici 2012-09-15 17:02:07 UTC
When I start gdm, it tries to use console 7 even though I have up to 11 as normal login consoles.

Reproducible: Always

Steps to Reproduce:
1.
2.
3.start gdm on a system where you have console 7 and > in use.
Actual Results:  
gdm tries to use console 7 and messes things up royally.

Expected Results:  
gdm should use the console after the last one in use.

Previous versions of gdm did do this correctly, although on my system they had other problems.

If you are using gdm with USE=-systemd, then in /etc/conf.d/xdm, make sure to set DISPLAYMANAGER="gdm" and CHECKVT="11" (or whatever other console is guaranteed to not be used for anything). Then /etc/init.d/xdm should in theory use that console when launching gdm.
Comment 3 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-09-15 18:46:06 UTC
Also, gdm-3.5.9 is long obsolete. Please update to 3.5.91-r2.
Comment 4 John Covici 2012-10-10 10:57:47 UTC
This is still present in gdm 3.6.0-r1
Comment 5 Alexandre Rostovtsev (RETIRED) gentoo-dev 2012-10-10 11:24:38 UTC
Then we probably need a gentoo-specific patch for gdm to read the value of CHECKVT from /etc/conf.d/xdm at runtime.

Something like the following logic:

if using systemd, do the automagic systemd thing.
else try parsing /etc/conf.d/xdm for the initial vt.
else fall back to GDM_INITIAL_VT for the initial vt.

Unless someone wrote and committed the patch that I described in comment #5, the problem is still present in our gdm-3.6.x.
Comment 8 John Covici 2013-01-23 05:44:53 UTC
In earlier versions of gdm, they did not check /etc/conf.d/xdm, but actually checked to see if the console was in use -- I have 11 text consoles already running and I don't want gdm to try to use console 7 because its logged in or has login running.  Maybe you could check /etc/inittab, or check the processes.
Comment 9 Gilles Dartiguelongue gentoo-dev 2013-01-23 23:20:12 UTC
so changing CHECKVT to 11/12 does not fix the issue ?
Please note that upstream does not care about this part of the code, really, it never worked properly in the 3.* series and will probably never will as upstream now relies on systemd to handle this. No matter how many patches we tried...

What is checkvt?  Is it some config option and if so, where does it go?
Comment 11 Pacho Ramos gentoo-dev 2013-08-24 13:22:42 UTC
this no longer occurs in 3.8
