Description Dave Burgess 2005-05-15 15:17:58 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050512 Fedora/1.0.4-2 Firefox/1.0.4

Description of problem:
When setting up FC4 T3 to run dual head with an ATI FireGL/T2 video card it fails to run in dual head mode.

Everything seems fine with system-config-display however after a reboot both screens come up and the various startup messages are displayed but as soon as X starts the second screen goes dead and the monitor indicates no video.  Even with the screens set to "spanning" only one screen is active, it's not simple the monitor (NEC 2080UX) that's not working.  Starting up system-config-display shows it set for dual head spanning desktops but it doesn't happen

Same symptoms for "individual desktop"

Fedora Core 4 Test 2 worked beautifully.

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

How reproducible:

Steps to Reproduce:
1. Install
2. Start system-config-display
3. Set for dual head mode
4. Restart
5. No dual head mode

Actual Results:  Screen one starts up fine but not screen 2

Expected Results:  Should have had dual head mode.

Comment 1 Mike A. Harris 2005-05-24 16:21:15 UTC
Dualhead configuration in system-config-display doesn't work properly.

Please attach your xorg.conf and X server log.  Also, when submitting
bug reports, please hit ENTER key after 70 chars or so so the bug isn't
all on one line.  It makes it impossible to read.

Thanks in advance.

This is from FC4 T2 and ATI dual head works beautifully.

This is the x xconfig file from FC4 T2.

Virtually identical to FC4 T2.

Comment 6 Dave Burgess 2005-06-07 16:28:11 UTC
After reading a lot of complaints about Matrox and DVI I decided.
To try removing the DVI cable and using analog cables on both monitors.

That gives me two live monitors but no matter what I do I can only get
"cloned" displays.  By that I mean both monitors show the same screen.

Not "individual desktops" - the same screen.

Comment 7 Frank Swasey 2005-06-16 19:01:54 UTC
I'm having the same issue with a Dell GX260 with a built in ATI 7000.  I
remember we had issues when FC3 first came out with these cards but it was
finally resolved.  Did we regress to busted code with FC4?

Comment 8 Frank Swasey 2005-06-17 00:10:34 UTC
Ignore Comment #7... It resolved itself after one more reboot after the yum
update finished.

Comment 9 Mike A. Harris 2006-06-14 16:53:47 UTC
