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.
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). 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. 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. 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? 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. Indeed, that fixes the problem perfectly for me :) Thanks! Fixed in CVS. Marking as fixed. Thank you! 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... |
