Description Gregory K. Ruiz-Ade 2003-12-04 23:41:32 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1)

Description of problem:
I performed an update of my Red Hat Linux 9 system (using apt against
freshrpms.net's redhat os and updates repositories).  After the update
finished, I restarted my machine, and at that point the X Radeon
driver would no longer detect the second display.  This results in
both my monitors displaying the same thing.  I miss my Xinerama (*sniff*).

The XFree86.0.log file at the above URL has the exact message at line 667:

(WW) RADEON(1): Only one monitor detected, Second screen will NOT be

Additionally, I have placed my XF86Config file at the above URL.

This configuration was working perfectly before the update.

The graphics card in question is an ATI Radeon VE (Dell Precision
350n) with dual-display support, configured for dual VGA outputs.

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

How reproducible:

Steps to Reproduce:
1. Configure X for dual-head Xinerama support
2. Start X
3. Watch X ignore the second head and start in single-head mode

Actual Results:  X started in single-head mode.

Expected Results:  X should have started in dual-head mode with
Xinerama support.
