My guess is this is on here somewhere but I have searched and even tried looking at bunch of other similar video problems.
My ATI 9550 shows up as laptop in displays after update to Ubuntu 12.04, how do I fix this?
I found the following command on another post
sudo lshw -c video.
I get this when I run that command:
*-display:0 UNCLAIMED description: VGA compatible controller product: RV350 AS [Radeon 9550] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0 bus info: pci@0000:01:00.0 version: 00 width: 32 bits clock: 66MHz capabilities: agp agp-3.0 pm vga_controller bus_master cap_list configuration: latency=32 mingnt=8 resources: memory:c0000000-cfffffff ioport:c000(size=256) memory:e5000000-e500ffff memory:e4000000-e401ffff *-display:1 UNCLAIMED description: Display controller product: RV350 AS [Radeon 9550] (Secondary) vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 32 bits clock: 66MHz capabilities: pm cap_list configuration: latency=32 mingnt=8 resources: memory:d0000000-dfffffff memory:e5010000-e501ffff"
This way more info than the command showed in he other post and as far as I can tell right.
This doesn't look to me like a laptop video would list?
I also see this command
xrandr, it reports this:
xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024 default connected 1280x1024+0+0 0mm x 0mm 1280x1024 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0
This is what shows in displays for resolutions but only the 1280x1024 works the others produce tearing in the video. Also I should have mentioned 3D mode does not work.
I have tried ATI/AMD drivers the new one won't load and older ones won't work. I found out the newer driver no longer supports the 9550.
