Description Håvard H. Garnes 2006-03-07 11:00:08 UTC
Upon upgrading from ubuntu breezy to dapper, Xorg was upgraded to version 7.0.0.
Then my Xinerama-config stopped working.

When I turn off xinerama both screens work ok in mirror-mode, but upon setting
xinerama on, the external monitor does not recieve any signals.

I will attach my config-file in a second.

xorg.conf

If I uncomment 

#	Screen	1	"screen1" RightOf "screen0"
#	Option		"Xinerama"

at the bottom, the second screen never recieves any signals. As it stands, the
second screen runs in mirror-mode.
Comment 2 Marius Gedminas 2006-03-14 19:43:56 UTC
I can confirm this:

  with X.org 6.8.2 MergedFB, Xinerama and plain dual-head layouts worked fine

  with X.org 7.0 MergedFB works (modulo bug 5565), while Xinerama and plain
dual-head layouts give no signal on the external monitor.

I used the VGA output in addition to the internal panel, so this is different
from bug 5571 (which talks about LVDS + DVI being unsupported).
Comment 3 Benjamin Herrenschmidt 2006-03-16 15:43:37 UTC
Please try with current driver from CVS. Use ati-1-0-branch to build against 7.0
or trunk if you build against a recent CVS snapshot of the server.
Comment 4 Håvard H. Garnes 2006-03-17 08:57:57 UTC
I am running packages from ubuntu. However, with a quick guide I could surely
compile and test ths if I can compile the driver only.
Comment 5 stian_web 2006-03-18 07:50:36 UTC
I would also be happy to test this, if you could tell us a little bit more. Do
we need to compile entire X.org or is there a way to only compile the cvs
version of the driver against our existing X.org?
Comment 6 Benjamin Herrenschmidt 2006-03-18 09:30:02 UTC
If you are running a 7.0 server, you just need to checkout the ati-1-0-branch
branch of the ATI driver from CVS and build that.
Comment 7 stian_web 2006-03-18 10:50:41 UTC
Indeed, that fixes the problem perfectly for me :) Thanks!
Comment 8 Håvard H. Garnes 2006-03-25 11:29:22 UTC
Fixed in CVS. Marking as fixed. Thank you!
Comment 9 stian_web 2006-04-15 01:45:03 UTC
Ehh. This bug was fixed when both my monitors were using VGA cable. When I
switched to one VGA and one DVI, the one attached with VGA goes black again.

With both connected to VGA, everything is fine now (which it wasn't before this
bug was fixed).

I know this bug is marked fixed, but I'm not sure wether I should file a new
one, or continue on this, since it's the same bug...
