Hi,

few days ago I've upgraded my system to Xorg 7.1.1 and KDM is the default session manager. After I've logged in, the X server crashes, thus I become a black screen and the login appears again afte few seconds. In the .xsession-errors file I get the following message:

Xsession: X session started for Li... at Thu Feb 1 01:35:39 CET 2007
open: Permission denied

What did X tried to open?
What can I do to get more detailed information about this error? strace'ing X by inserting "/usr/bin/strace -f -F -o /tmp/outfile /usr/X11R6/bin/X -br -nolisten tcp :0 ....." in /etc/kde3/kdm/kderc didn't work.
Could it be possible, that the DRI module can't be loaded? ((EE) AIGLX: DRI module not loaded)

Neither KDE nor Afterstep, Gnome etc. are currently running.


Before I've done the upgrade I've had nearly the same problem with the XFree86. I must at first login as root, logout and re-login as user to get KDE running. Otherwise KDE crashes at the point "initialize system" the second "boot-point" beneath the splash-screen. With xorg root can't log in due to security reasons I think.

I also recently upgraded to Xorg 7.1, but I am having different problems enabling DRI. Anyways, it sounds like perhaps users do not have access privileges to the x server. I am not certain, nor an expert, but I would assume it was trying to open the display, but could not because of improper access privileges for users. I do not know the solution off the top of my head. Perhaps you could search for similar problems along those lines.

Also post any errors listed in the Xorg log file (/var/log/Xorg.0.log)

this is a rights issue i think, try to see if you can get X running as root.
if root can start X, then the user does not have the correct groups.

first I would say thanks to you for your answers. I regret that i'm late to answer due to no-connectivity to the internet caused by a non-working X-server... (I should not go online at work)

The problem is fixed by me yesterday. Teh X-server is now up and running. to fix this problem I've installed gdm and started gdm from shell. Then I get the warning, that gdm can't write a file (.X0-lock??) to the /tmp diretory. The reason was the permisson to /tmp. It was set to

drwxrw-rw- 13 root root 16384 Feb 2 01:14 tmp
now
drwxrwxrwx 13 root root 16384 Feb 3 02:30 tmp
