ForceMonitors seems broken in 8.3

[tsuru]

I'm running on a Asus notebook with a Mobility 9600 (M10) gpu. The lvds display is 1280x800 native and I have an attached 22" 1680x1050 native display to crt1.

When at home, I want to run my laptop with the lid closed -- no lvds display -- and solely run on the crt display. As recently as Catalyst 8.2, I could specify Option "ForceMonitors" "nolvds,crt1" and everything would work perfect. OpenGL ran and Xv video also ran, both at the native 1680x1050 for the external display. After upgrading to Catalyst 8.3, this is no longer the case. I can not get native resolution on the secondary display when ForceMonitors or EnableMonitor options are listed.

If I remove the ForceMonitors and EnableMonitor options I will get native resolution on both displays. However, Xv video only will work on lvds. I looked at the Xorg.0.log and it shows that when ForceMonitors or EnableMonitor is specified, the EDID or DDC for the crt1 montior isn't detected correctly:

I really hope ForceMonitors returns to it's old functionality in the next release :(


[Edit] I think I fixed it further down in the thread. PEBKAC

[sastraxi]

I'm getting the same results, however I do not appear to have ForceMonitors or EnableMonitors specified in my X server configuration file.

You might want to try backing up, then deleting, /etc/ati/amdpcsdb. If you ever ran aticonfig --enable-monitor or aticonfig --force-monitors it could have been saved in that.

[sastraxi]

Thanks for the tip; however, it didn't solve my problem. I don't wish to hijack your thread any longer -- so I'll just say I hope someone comes along and provides an answer for your (and possibly my!) problem.

[guillepb]

I get the exact same behaviour you're getting (and I'm probably just about as annoyed by it as you are).

However, checking my Xorg.0.log file I've seen that my external monitor is also detected correctly if I use force-monitor, but forcing the LCD panel of my laptop (i.e. lvds,nocrt1).

EDID data is only wrong for the exernal monitor (a Dell2007WFP in my case) if I force it (i.e. crt1,nolvds), and then I'm stuck with 1024x768.

I hope they come with a solution for this in 8.04...

[xeros]

I can confirm that bug, too.
ForceMonitors and MonitorLayout options are very problematic for me from at least 8.41 fglrx version (I haven't tried fglrx before 8.41 - I was using opensource radeon driver just fine with dualhead/multiseat on Kubuntu 6.06).

[tsuru]

Well I got mine working a while back... I'll post the relavant sections here (no fonts, modules, or input). I didn't test ForceMonitors but I think it should work too, my key changes being the Screen setup, ServerLayout, and the Mode2 etc options of the Driver section.

It is my impression, driver-wise, the following have the same effect.
Option "DesktopSetup" "s"
Option "EnableMonitor" "crt1"
and
Option "ForceMonitors" "nolvds,crt1"

Actually after looking at this again, I remembered one more thing I did just before it started working again: Make sure the monitor with the larger resolution is listed first in the file. IIRC that was key. Sadly, I didn't maintain scientific vigor while fixing and made 2 or so changes at a time towards the end.

[guillepb]

Well, 8.4 didn't fix the issue for me :-(

[tsuru]

Well, 8.4 didn't fix the issue for me :-(

I haven't tried 8.4 yet but 8.3 is now working fine for me (see above). Did you try putting your external screen definition first in xorg.conf ? How about the Mode2 etc settings in the driver? If all that fails, what does your xorg.conf look like?

[guillepb]

Yeah, I tried your proposal and it didn't work for me. However I suspect some useful options may be missing, my Device section in xorg.conf is way lighter than yours:
