Red Hat Bugzilla – Bug 168678
6.8.2-1.FC3.45 X server refuses to start 2nd ati head in multi-head display
Last modified: 2007-11-30 17:11:13 EST
Description of problem:
xorg-x11 refuses to use 2nd display in multi-head display. The second display
uses the ati driver and is an "ATI Technologies Inc Rage XL (rev 27)". This is
a regression. It worked fine with xorg-x11-6.8.2-1.FC3.13. It stopped working
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot system.
xdm will start X server, but will use only main head and not 2nd one.
X server should use both heads.
I will attach copies of some logs.

I tried adding Option "nolinear" to the "Device" section for "ATI". It still
failed, but in this new & different way.

I noticed that this latest updated involved changes to DRI for the "ati"
driver, so I tried removing the Load "dri" line. But it didn't help. Here's
the output from that.

/var/log/Xorg.0.log with 6.8.2-1.FC3.45 with "nolinear" and no "dri" (still fails)
To round things out, I tried both Option "nolinear" and removing Load "dri".
It still failed.
This is probably a duplicate of bug #168752 but with different symptoms.
Since it is slightly different symptoms, we'll track it as a separate issue
for now until we gather more details.
Please test the rpm packages located at the following URL, and provide a
status update as to wether or not they change things for you or not.
Setting status to "NEEDINFO_REPORTER", and awaiting results of testing.
Oops, I gave you the FC4 test URL. Here is the FC3 one:

With the new rpm's you mention, the X server is using the 2nd head just fine
again. Also, from the official Fedora Core updates, I downloaded rpm's with
the same version number, but different checksums, and they work equally well.
I'm attaching the log of the successful startup with these new rpm's.
