Multi-head still has issues with UMS that I haven't had time to sort out yet, for now you can use KMS. (In reply to comment #7) > Multi-head still has issues with UMS that I haven't had time to sort out yet, > for now you can use KMS. > Sorry for not being more clear: I am mainly using KMS, UMS was just a test. Dual head is NOT working for me even in KMS mode. At some point in the boot process (upon radeon module initialization ?), one head goes down and cannot be switched on again... Created attachment 33517 [details] [review] fix This should fix it. I've sent it upstream. (In reply to comment #9) > Created an attachment (id=33517) [details] > fix > > This should fix it. I've sent it upstream. > Ok, I have applied, on top of drm-radeon-testing (aa5120d...), that fix and the one for fdo bug 26551, which seemed also relevant. Dual head now works as expected ! Thanks for you efficiency. |

Created attachment 33452 [details] Xorg log with UMS and minimal xorg.conf Hello, I am trying a dual head setup with no success so far... Hardware: Radeon HD 5850 (1002:6899) Primary monitor: DVI-D Samsung SyncMaster 1920x1080 connected to DVI-1 output Secondary monitor: VGA Acer AL2216W 1680x1050 connected to DVI-0 output (with DVI-A/VGA adaptator) Software: Ubuntu Lucid kernel 2.6.32 + drm from drm-radeon-testing (git commit 45fa67...) xorg 1.7.5 radeon ddx 6.12.99 (git commit a3b730ec...) The desired setup is to have the primary monitor right of the secondary one That is primary at +1680 +0 and secondary at +0 +15 What I have tried: * KMS with minimal Xorg.conf Dual Head setup using xrandr or gnome-display-properties * UMS with minimal Xorg.conf + 'Virtual 3600 1080' display option Dual Head setup using xrandr or gnome-display-propertie * KMS with dual head setup in Xorg.conf What happen: The secondary display (the VGA one, connected to DVI-0) always stays off There is also sometimes bug in with the cursor: it can't reach all part of the display, it appears to hit some 'invisible wall' like if the right edge of the desktop was in the middle of the screen.
