Haven’t tried, but the ATI 3D drivers are not supported, and the open-source Xorg drivers used instead say they don’t support 3D acceleration features.
Would not remember default selected resolution for my Radeon X1300 card (connected to HDTV. Insisted on showing 1080p resolution, but I wanted 720p).
After a lot of wasted effort, determined the proprietary ATI Radeon drivers are NOT supported in Ubuntu 11.04 for my old card. I ended up sticking with the fbdev drivers (the default system-selected Xorg driver). Also wasted lots of time trying to edit Xorg.config, with poor results. All the information telling you to edit Xorg.config is mostly outdated for Ubuntu 11.04.
Ultimately, thanks to this page: http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.html ...I figured out the solution. The page describes Gnome, but I am on KDE (Kubuntu), so I modified it. Ultimately, I added the following code to /etc/X11/Xsetup file:
xrandr —newmode “1360×768_60.00” 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsyncxrandr —addmode DVI-0 1360×768_60.00xrandr —output DVI-0 —mode xrandr —output VGA-0 —mode 1360×768_60.00
(again, values were determined using xrandr and cvt utilities.)
