Severity: important<br>
<br>
Dear Maintainer,<br>
<br>
For a few months I am unable to login using gdm3. The greeter shows up<br>
normally, but upon entering login information the screen flickers and the<br>
system becomes barely-responsive for a few minutes, until I am left with a bare<br>
TTY login prompt - this appears to be the result of gnome/gdm3 frantically<br>
retrying and failing to start.<br>
<br>
The X.org log contains the following info:<br>
<br>
(WW) xf86OpenConsole: VT_ACTIVATE failed: Operation not permitted<br>
(EE) Fatal server error:<br>
(EE) xf86OpenConsole: Switching VT failed<br>
<br>
However, using lightdm I can login fine, so this does not seem to be an X.org<br>
or driver-related problem, but rather something about gdm3.<br>
<br>
Installing xserver-xorg-legacy does not solve this issue, however it did<br>
produce a dmesg line about a segfault in libgtk-3-0.so. Reinstalling<br>
`libgtk-3-0` got rid of the segfault, but still no luck - now with `xserver-<br>
xorg-legacy` installed I'm getting the following in demsg:<br>
<br>
traps: gdm3[1318] general protection ip:564e456e74c2 sp:7ffc3c4017c0<br>
error:0 in gdm3[564e456ce000+5d000]<br>
<br>
Reinstalling gdm3 does not get rid of this message, and I am still unable to<br>
login when using gdm - getting a constant flicker for about a minute until it<br>
finally gives up. At the same time, lightdm manages to log in without any<br>
problem.<br>
<br>
The system has an integrated Intel graphics (Ivybridge / Intel HD4000), and no<br>
other graphics adapter installed. I'm using the KMS driver.<br>
<br>
The problem only occured after the update to 3.22.3-2, so this does not seem to<br>
be a duplicate of bug #857995<br>
