I believe what is happening to you often happens on several of my faster
machines.
The following represents evidence of what happens here using KDM or TDM and
Xorg/X11:
# egrep 'dev/dr\|Xorg.0.' /var/log/Xorg.0.*
/var/log/Xorg.0.log:[ 19.936] (==) Log file: "/var/log/Xorg.0.log", Time:
Sun Sep 29 15:29:38 2024
/var/log/Xorg.0.log:[ 19.938] (II) xfree86: Adding drm device
(/dev/dri/card1)
/var/log/Xorg.0.log:[ 19.974] (II) modeset(0): using drv /dev/dri/card1
/var/log/Xorg.0.log.old:[ 4.892] (==) Log file: "/var/log/Xorg.0.log",
Time: Sun Sep 29 15:29:23 2024
/var/log/Xorg.0.log.old:[ 4.910] (EE) open /dev/dri/card0: No such file or
directory
/var/log/Xorg.0.log.old:[ 4.910] (EE) open /dev/dri/card0: No such file or
directory
/var/log/Xorg.0.log.old:[ 4.910] (EE) Please also check the log file at
"/var/log/Xorg.0.log" for additional information.
#
What this shows is that KMS had not yet succeeded to provide KMS services, so
/dev/dri/cardX did not yet exist, before the DM tried to start. After about
15 seconds, the DM tried again, and succeeded.
What I suspect is that on your system, GDM isn't configured to automatically
retry, so you get no GDM until you start it manually.
I've yet to determine how to ensure the DM doesn't try to start before KMS
has been made ready.
You may be able to get similar data as I get grepping Xorg.0.lo* by seeking
equivalent data from your journal.
