Hi, 

I'm having the same issue and removing the. ICEAuthority* files fixed the issue 
here as well. 

Thank you for the fix Philipp .

Bug#897975: gdm3: System fails to boot due to GDM restarting constantly.

2018-05-12 Thread Mladen Mijatov 
Looks like it does boot after ten minutes or so. It seems only Wayland
variant of gdm is failing. Gnome on Wayland has no issues though.

Bug#897975: gdm3: System fails to boot due to GDM restarting constantly.

2018-05-12 Thread Tom 
Package: gdm3
Version: 3.22.3-3+deb9u1
Followup-For: Bug #897975

Dear Maintainer,

I observe the same problem on my notebook and would like to add some additional
information.

1) CPU Intel(R) Celeron(R) CPU  N3160 with integrated graphics. This might be
interesting, as there is one (EE) entry from the X-Server seen in the gdm3
debug log (see 3)

2) I enabled debugging in the gdm3 configuration - in my case gdm3 still fails.
The error message in the logs (see attachment) is:

(EE) open /dev/fb0: Permission denied

3) I disabled wayland in the gdm3 configuration - gdm3 still doesn't start

4) As a workaround I installed lightdm - which works fine.

Best regards,

Tom

Followup-For: Bug #897975

Dear Maintainer,

after recent upgrade, gdm3 also fails to start as for the other reportes.  It
doesn't even switch to graphical mode and so the few text boot messages stay
visible.

In contrast to previous reporters, I do not see the "ICELockAuthFile fail"
error in my logs.  To narrow down problems I enabled debug mode in
/etc/gdm3/daemon.conf (as attached) and then gdm3 simply starts.  Disabling
debug mode makes gdm3 fail again.

Funnily enough, the last packages upgraded before the failing boot were pretty
innocent:

2018-05-07 Thread Philipp Falk 
Package: gdm3
Version: 3.22.3-3+deb9u1
Severity: wishlist

Dear Maintainer,

I just wanted to confirm that I also encountered this bug on a debian
stable installation.

I also see the "ICELockAuthFile fail: Already exists" message in
the systemd journal.

Removing /var/lib/gdm3/.ICEAuthority* and restarting
gdm.service fixed the issue temporarily until the next reboot.

If wayland is enabled via /etc/gdm3/daemon.conf, gdm3 comes up after
some waiting time (around two minutes) on a cold boot.

Bug#897975: gdm3: System fails to boot due to GDM restarting constantly.

2018-05-05 Thread Mladen Mijatov 
Package: gdm3
Version: 3.28.1-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,

After recent update system is unable to boot due to GDM3 constantly restarting.
Journal contained message "IceLockAuthFile fail: Already exists" before GDM
exiting and starting againg.

Other than this I was unable to find any other issue.

Only solution I could find to make my system usable again is to install LigthDM
