 Posted: Mon May 07, 2007 2:34 am Post subject: [SOLVED] Issues with radeon dual-monitor after X.org update |
 |
|
Hi!
I just updated x.org to 7.2. I'm using the open-source radeon driver for my trusty Radeon 7000 card with dual vga-out, connected to two monitors.
I've been using the "merged framebuffer" mode (which has some advantages over Xinerama), configured as:
| Code: | Section "Device"
Identifier "ATI Radeon 7000"
Driver "radeon"
Option "MergedFB" "true"
Option "CRT2Position" "LeftOf"
EndSection
Section "Screen"
Identifier "Dual Monitors"
Device "ATI Radeon 7000"
Monitor "19ers"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1280x1024" "1024x768" "800x600"
Virtual 2560 1024
EndSubsection
EndSection
|
This used to work beautifully with x.org 7.1, giving me a 2560x1024 desktop spanning my two monitors. After the update, however, the two monitors show the same (cloned) image, with a virtual desktop of 2560x1024, scrolling with the cursor at the edge. It is almost as if the "MergedFB" option stopped working, although according to the documentation for the radeon driver, it has not changed.
Any ideas?
System info below, for completeness:

Hi,
the output of | Code: | | cat /var/log/Xorg.0.log |
might give some usefull information.

Hi,
I had the same problem and passed three hour to understand what happens...
It seems version 6.6.3 of xf86-video-ati doesn't work well with xorg-server 1.2. Hell, i don't understand why, but anyway you have to push to version 6.6.191.
So add the following to one of your /etc/portage/package.unmask files:
| Code: | | x11-drivers/xf86-video-ati |
And add the following to one of your /etc/portage/package.keywords files:
| Code: | | x11-drivers/xf86-video-ati ~x86 |
Then re-emerge xf86-video-ati:
| Code: | | emerge -av1 x11-drivers/xf86-video-ati |
And all should go well again after restarting X11. And yes!! You have a bonus with those versions of xorg-server and xf86-video-ati... gdm now seems to start directly in mergedFB mode which was not the case before!  
Hope this helps!
Regards, Didier. |

SnakeByte, you're absolutely right, I should of course have posted relevant output from the X log. I have to admit that, at the time, I was quite frustrated and hadn't gone through it carefully enough at that point. There's been several hours of trying to debug it since, though... 
Anyhow, ptitjes, you hit it (almost) spot on!
I switched to xf86-video-ati 6.6.191. It still wouldn't work. After examining the x.org log it turns out that the new version (for some reason) still insists that no monitor is connected to the 2nd vga output. This [i]did[i] work before the upgrade. However, adding | Code: | | Option "MonitorLayout" "CRT, CRT" |
made X finally accept that there is in fact a monitor there. So, I'm back at 2560x1024 and very happy!
Thanks a lot for your help - I very much appreciate it!
Btw, ptitjes, do you know if this issue has been reported anywhere (I'd presume that the gentoo bugzilla would be the correct place, since it's essentially an incompatibility between package versions)? |

I've no idea. In fact, airlied announced the 6.6.191 like this :
| Quote: | This is pre-release of the ATI driver aimed at 7.3. It doesn't contain randr1.2
support it does however contain a major re-write of the output mappings from
what was known as Alex's superpatch. Please logs all regressions into bugzilla
so we can fix them before the 6.7 release. |
So i can't find through the release notes why this works better with xorg-server-1.2 than the previous version.
Anyway, if you want to endorse that, maybe you could first file a bug so that 6.6.191 be unmask...
Regards, Didier.
Edit: Added link to release notes. |

| Thanks, this worked for my laptop too. Unfortunately, the colors in the external monitor are all weird, as if it has only 8 color support. The laptop display is fine. |

| Downgrading to the stable version of xf86-video-ati solved my issue. Apparently, all that is needed is reemerging xf86-video-ati, it doesn't require the masked version. |
