My guess is this is on here somewhere but I have searched and even tried looking at bunch of other similar video problems and couldn't find a way that works.
My ATI 9550 shows up as laptop in displays after update to Ubuntu 12.04, how do I fix this?
I can't run 3d mode and Displays shows laptop and all the settings but one won't work on my monitor.
I found the following command on another post "sudo lshw -c video". I get this when I run that command it shows,
" *-display:0 UNCLAIMED

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 shows 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
640x480 0.0 "
This is what basically shows in displays for resolutions but only the 1280x1024 works the others produce tearing in the video.
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.
