Hello,

I recently observed that whenever I start the laptop, two instances of X are started alongwith 2 GDM instances. Can someone tell me why the second instance is started? I did a fresh install of HArdy Beta (now upgraded to release) but copied my home directory in order not to lose my customizations and private files, can this be related to that?


$ ps -ef | grep -i gdm
root 5435 1 0 07:59 ? 00:00:00 /usr/sbin/gdm
root 5442 5435 0 07:59 ? 00:00:00 /usr/sbin/gdm
root 5453 5442 3 07:59 tty7 00:19:06 /usr/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7
root 5720 5453 0 07:59 tty7 00:00:00 /usr/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7

That is odd. For one reason, X server can not live twice (or more) on the same display (:0), so I don't even see how this is possible.

That's the reason I was stumped too...anyone? I checked gdm.conf but there is nothing which could point out to this....

Hello,

+1

Fresh install, x86_64. Everything works fine. pstree (or looking at the ps output properly) shows they're spawning each other:
├─gdm───gdm─┬─Xorg───Xorg
So I assume this is by design.

Are you using the ati binary driver? Its a known bug using when the proprietary driver from ATI.

Hi,

Thanks for the tip.

After disabling ATI binary drivers, the two instances of X stopped, but two instances of GDM are still there:


~$ ps -ef | grep gdm
root 5410 1 0 17:25 ? 00:00:00 /usr/sbin/gdm
root 5417 5410 0 17:25 ? 00:00:00 /usr/sbin/gdm
root 5424 5417 1 17:25 tty7 00:00:01 /usr/bin/X :0 -br -audit 0 -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7

I'm using Ibex.

I disabled the ATI proprietary driver and rebooted. Now only 1 instance of gdm appears.
