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

Oops. I accidentally replied privately to dev <at> jpoiret.xyz, not 
mentioning 57589 <at> debbugs.gnu.org. I hope the history can be recovered 
from this message.

Josselin recommended to

- check permissions on /tmp/.X11-unix/ (gdm user should have r+w 
permissions)

    shegeley <at> zone51 /tmp$ ls -lah .X11-unix/
    total 0
    drwxrwxrwt 2 gdm      gdm    80 сен  5 16:12 ./
    drwxrwxrwt 6 root     root  160 сен  5 16:16 ../
    srwxrwxrwx 1 shegeley users   0 сен  5 16:12 X1
    srwxr-xr-x 1 gdm      gdm     0 сен  5 16:12 X1024

-  check /var/lib/gdm/, doesn't have the proper permissions

   Hm. That's really strange. For some reason /var/lib/gdm had
   "transmission" as user-group. I assure you that I didn't explicitly
   do any "dirty stuff" like that permission changing in my config


   shegeley <at> zone51 /tmp$ sudo ls -lah /var/lib/gdm
   total 0
   drwx------ 1 gdm  gdm           38 авг 26 21:46 .
   drwxr-xr-x 1 root root         248 авг 28 18:37 ..
   drwxr-xr-x 1  973 transmission  62 авг 26 21:46 .cache
   drwx------ 1  973 transmission  44 авг 26 21:46 .config
   drwx------ 1  973 transmission  10 авг 26 21:46 .local
   shegeley <at> zone51 /tmp$ sudo chown -R gdm:gdm /var/lib/gdm
   shegeley <at> zone51 /tmp$ sudo ls -lah /var/lib/gdm
   total 0
   drwx------ 1 gdm  gdm   38 авг 26 21:46 .
   drwxr-xr-x 1 root root 248 авг 28 18:37 ..
   drwxr-xr-x 1 gdm  gdm   62 авг 26 21:46 .cache
   drwx------ 1 gdm  gdm   44 авг 26 21:46 .config
   drwx------ 1 gdm  gdm   10 авг 26 21:46 .local


After changing it was able to launch into GDM, but with X11 as display 
manager :( Attached new logs.
