Description d_martin 1999-06-29 04:31:10 UTC
I have RH 5.1 installed, and I'm running xdm with a Diamond
3000GT 4MB video card and the XF86S3V X server.   Whenever
any user logs out of their X session, the screen goes wavy
and the system completely locks up.  It does not matter if
the user is root or a non-root user.

I have tried updating the RPMs to the latest XFree86 RPMs
available for RH 5.1 and this did not help.  I also have
tried changing window managers, and the problem occurs on
all 5 window managers I've tried (FVWM, FVWM2, WindowMaker,
E, and Afterstep).

There doesn't seem to be a problem with this if I use startx
to start my session, only xdm.  The X server is running in
16bpp mode at 1600x1200 (but the problem happens no matter
what resolution I use, I've tried others)

I doubt this is relevant, but I also have a 12MB Voodoo2

I am pretty good at configuring X and I'm also pretty
knowledgable about my hardware, so please feel free to
contact me at or if you would like more information
about this problem.  I have included all the information
that I can guess would be relevant, but I could easily have
left things out... :)

I would appreciate all e-mail regarding this be cc: to both  and

Oh, the chip in the video card is an S3 Virge.

Comment 2 David Lawrence 1999-07-01 19:10:59 UTC
We do not currently have one of the cards in question here so we may
need to get one into the lab before we can accurately test this bug. I
am assigning it to a developer to see if he has any further

Comment 3 Preston Brown 1999-07-06 14:51:59 UTC
my suggestion is to add the line:

DisplayManager._0.terminateServer: true to your
/etc/X11/xdm/xdm-config file and see if the problem goes away.

Thanks. I did that and it fixed the problem.
