Subject: gdm3: gdm blank screen

Date: Thu, 09 Aug 2012 15:06:55 -0700

Package: gdm3
Version: 3.4.1-2
Severity: important

After updating from Squeeze to Wheezy, the gdm login screen never appears on
boot, instead, it ends up in a blank screen with the cursor spinning.
Moving the pointer works.
Switching to a virtual console works.
Entering a X session (ie. startx) from a virtual console works.

I see the same problem, at version 3.4.1-3, after each reboot.

I can press Atl-Ctrl-Backspace to cause the X server to die, then X
and the greeter restart correctly.

Subject: gdm3: Facing the same problem, attaching debug logs

Date: Mon, 05 Nov 2012 23:28:10 +0400

[Message part 1 (text/plain, inline)]

Package: gdm3
Version: 3.4.1-4
Followup-For: Bug #684432

I am facing the same problem during one of dist-upgrades. Attaching gdm
log files (with debug enabled in daemon.conf). Unfortunately I was
not able to digest a reason out of them.

Subject: SELinux is the Reason

Date: Tue, 6 Nov 2012 01:43:16 +0400

Based on IRC discussion the reason was identified to be
pam_selinux.so plugged through /etc/pam.d/gdm3-autologin
that produces:

gdm-welcome][5739]: DEBUG(+): GdmSessionWorker: received
pam message of type 2 with payload 'Would you like to enter
a security context? [N]  '

interactive prompt. On my system selinux is in permissive
mode. gdm loaded fine after I relabeled file systems.

I do not use autologin. Instead I commented out the selinux lines
in /etc/pam.d/gdm3 and now the very first gdmgreeter (after reboot)
works. Thanks!

The real fix for this issue, is to properly set the security context on
the /usr/sbin/gdm3 executable.

-rwxr-xr-x. 1 root root system_u:object_r:xdm_exec_t:s0 263592 oct 20 17:53 /usr/sbin/gdm3

You should check that you have at least the
package selinux-policy-default (2:2.20110726-11) installed and relabel
your filesystem (touch /.autorelabel && reboot).

Sorry, seems I spoke too soon. After commenting out selinux from the
/etc/pam.d/gdm3 file I "know" I rebooted and seen the greeter come
alive. But then, on further reboots, it (again, still) does not work.
I still need  Atl-Ctrl-Backspace to kill that very first X server, so
subsequent gdm-session-worker goes on to spawn gdm-simple-greeter.

Subject: [gdm3] blank screen: Cannot find a free VT

Date: Mon, 28 Jan 2013 16:24:49 +0100

Package: gdm3
Version: 3.4.1-5

After dist-upgrade from squeeze to wheezy gdm3 offers no login prompt
anymore. Instead the screen stays blank, the cursor keeps spinning,
while X respawned multiple times. Maybe related to #681830.

Current gdm3 log shows

> Fatal server error:

...
> (WW) xf86CloseConsole: KDSETMODE failed: Bad file descriptor
> (WW) xf86CloseConsole: VT_GETMODE failed: Bad file descriptor
