Package: gdm
Version: 2.20.7-4lenny1
Severity: important
This bug occurs when using the radeonhd X.org driver on my Lenny
machine, dellbuntu. It does not occur when using the radeon X.org driver.
Steps:
1) I run the gdmchooser from the gdm login screen on my Lenny machine,
which correctly lists the other machines on my network (circle,
octagon, ubuntu804). The Lenny machine is called "dellbuntu" (guess
where I bought it).
2) I choose to connect to either octagon or circle. I see the X.org X
appear, then the white "swirly disc" cursor of the machine I am
connecting to for a moment, then X crashes and I am returned to the
Lenny gdm screen.
I have tried connecting to both a Debian Etch machine (circle), and to
two Ubuntu 8.04 machines (octagon and ubuntu804). One of the Ubuntu 8.04
machines (ubuntu804, which is a vmware vm on circle) works. The other
two machines show this problem.
I have tried using X to directly connect to circle or octagon from
dellbuntu, the Lenny machine, e.g.:
X -query circle :1
which works correctly.
On circle (Debian Etch), when I try to connect from dellbuntu via
gdmchooser, /var/log/daemon.log shows this:
Apr 24 15:02:24 circle gdm[31902]: gdm_slave_xioerror_handler: Fatal X
error - Restarting dellbuntu.esfnet:0
On octagon (Ubuntu 8.04), a failed connection from dellbuntu via
gdmchooser gives this in /var/log/daemon.log (looks like I have at some
point upped the debugging on octagon). Note that dellbuntu.esfnet has
