Description of problem:
loging out as either ROOT or a NORMAL user to switch between them
causes my machine to hang just showing the hourglass on a black
My hardware is as follows :-
AMD K6 III/450
384 Meg of ram
ASUS P5A with latest BETA bios
MATROX G400 graphics card
MITSUBISHI Diamond Plus 72 monitor
Microsoft PS/2 wheel mouse
The problem persists even after a full update.
I picked gnome-sesion to report this under but it may be more to do
with a graphics card driver problem or the X-window subsystem now
NB this is definatly not a hardware problem as RH9 is installed on
another disk drive and works flawlessly.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.log out as the current user
Actual Results: loging out as either ROOT or a NORMAL user to switch
between them causes my machine to hang just showing the hourglass on a
Expected Results: graphical login screen being displayed.
I have almost the same problem with my Dell Optiplex GX240 with ATI
Rage 128 Pro Ultra TF using the r128 driver in X. When i logout from
Gnome the screen goes black and the machine freeze completely, not
even hourglass and does not respond to ping anymore. Choosing shutdown
or restart works, also logging out via Ctrl-Alt-Backspace works.
Machine is fully updated including kernel-2.6.5-1.350.
Option "NoAccel" "yes" in /etc/X11/xorg.conf makes the problem
disappear but makes screenupdates very slow.
Having finally got all of the Core 2 release CD's burnt and tested I
have installed it cleanly on the disc where test 3 was and the problem
still persists but slightly differently in that the screen is totally
blank with no hour glass cursor now and as before the only way out is
to reset the machine.
I have edited the /etc/X11/xorg.conf file putting in the line Option
"NoAccel" "yes" as the last line in the device section and as Karl
observed in test 3 the problem goes away in the release version.
I am updating the bug from test3 to release 2
I have found that commenting Load "dri" is a much better way for me to
work around the problem. Works for me in FC2 at least.
Yes I agree it produces much improved screen updates compared to the
original FIX of adding Option "NoAccel" "yes" in /etc/X11/xorg.conf
Reassigning bug to xorg-x11 component.
Having read bug report 125762 re a matrox millenium graphics card it
would definately suggest that the problem described in this bug report
was relatated to the MGA driver also.
