Note: there is a thread regarding this on the openSUSE forums, with relevant discussion beginning here: https://forums.opensuse.org/showthread.php/490418-Help-Configuring-Multiple-... As noted in that thread: - Stratos tested with radeon+radeon, and as can be seen in the Xorg log above, the second radeon adapter is not found. In addition, the "--listproviders" only shows the one adapter. Obviously, one big desktop can not be achieved. - Stratos additionally tried with mixed adapters; radeon+nouveau ... in that case, the Xorg log showed both adapters. Similarly, "--listproviders" indicates the two adapters. However, after issuing a "--setprovideroutputsource", xrandr indicates that the outputs on the second adapter are disconnected, and one big desktop spread across the outputs of the multiple adapters can not be achieved. I then tested this and found that: - with radeon+radeon, openSUSE 13.1 works fine (meaning Xorg log is correct, providers all detected, setting the providers works, xrandr correctly reports all outputs, and one big desktop can be achieved ) - updating the kernel (I went to 3.13.6) and graphics stack results in a regression that was (strangely) unlike Stratos' radeon+radeon case, but precisely like his radeon+nouveau case. My knee-jerk reaction is that Airlie and/or Deucher mucked something up in either the DRMs, libdrm, the server, or the DDXs when they introduced runtime PM ...If I'm not mistaken, Dave added that feature to intel and nouveau (for optimus systems) in 3.12 and Alex did likewise for powerxpress systems in 3.13 (My suspicion is that they did not test this new feature, that is currently supposed to be limited to hybrid laptops, with an ordinary multi-gpu desktop systems). If so, they owe me a beer. Bring back my multi-gpu driven, xrandr configured, desktop! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Latest (today's) update from xorg repo, breaks everything. X server is not starting at all due to a glamor exception.

I will keep testing as soon as there are new packages.

I have current X11:XOrg running on a ATI Radeon "CAICOS" (ChipID = 0x6771) graphics card. Works with EXA and glamor as AccelMethod. Make sure you have glamor packages uninstalled and reinstall xorg-x11-server, since glamor is now part of xorg-server. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
