Description Joachim Backes 2002-05-15 08:36:09 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.79 [en] (X11; U; Linux 2.4.18 i686)

Description of problem:
Standardly, I am running the gnome desktop as my standard desktop.
Now, I switched to kde by the switchdesk tool, logged out und started x again.
Then the KDE desktop is running correctly.

Now, I switched back to gnome using again switchdesk, then I shut down X and
started X again for getting my gnome desktop. But during starting up X, X hangs
up (only the X11 screen appears and the cross mouse pointer, but no gnome
greeting logo).

I rebooted. Then X start successes with a full gnome desktop.

Remark: I don't use xdm; I always start the X environment by using startx.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Take gnome as std desktop
2. Use switchdesk for selecting KDE
3. Kill X and start it again by "startx", then the KDE desktop appears and runs
4. Use switchdesk for selecting GNOME
5. Kill X and start it again by "startx", then X starts but hangs up.

Actual Results:  X hangs

Expected Results:  X starts the gnome desktop

All switchdesk does here is "exec gnome-session", which seems to be right... 

Comment 2 Havoc Pennington 2002-05-21 15:48:32 UTC
No clue - we'd need to see which process was hanging, and probably strace that

Comment 3 Joachim Backes 2002-05-28 12:39:39 UTC
It seems that X can't no more load the video driver mga (my video card is a
matrox g400) when starting X after I re-switchted to gnome. 

I got the following output when starting X (which will hang):

	If the server is older than 6-12 months, or if your card is
	newer than the above date, look for a newer version before
