I know what you mean about more linux-oriented forums but so far havent had much luck there and for some reason I find the most helpful people on this forum, like you. I was able to install the fglrx package, but unable to switch to that driver. System>Preferences>Monitors only shows the Monitor as "laptop", and the "detect monitors" button does nothing. The installation adds an ATI control panel menu item which doesnt do anything, but tells me to run aticonfig which tells me no ATI cards recognized.
Seems like I am using the radeon driver since lsmod shows radeon loaded and /var/log/Xorg.0.log has many references to RADEON(0)
Might there be a different driver or technique that will enable me to gain higher than 1024x768 resolution under 10.04?
