I installed Kubuntu V7.04 (Feisty Fawn) on Carhith's PC. Everything seems to work fine so far, but one thing that always seems to cause trouble under Linux, regardless which distibution I try, doesn't work there as well: 3D support.
She has an ATI Radeon 9700 graphics card, so I searched the web and found this howto (it's in German, sorry), which describes how to install 3D support for ATI cards. Basically, it says to install the xorg-driver-fglrx package and modify the xorg.conf.
Instead of using apt-get in the console, I used the adept installer to install the xorg-driver-fglrx package. After this, I edited the xorg.conf as described in the howto, which means I replaced "ati" by "fglrx" and added
Code: Select all
Section "Extensions"
Option "Composite" "Disable"
EndSectionNow, after a reboot, the effect is the following:
3D acceleration works (i.e., I can run fgl_glxgears and it works), but there's a problem with the mousepointer. When it is moved towards the buttom of the screen, graphic errors suddenly appear. It's like a narrow vertical band of random coloured pixels (maybe 32 or 64 pixels wide) from the top to the buttom of the screen. It also follows the mouse moves while turning back to the mouse pointer every now and then. But even more problematic is that the displayed mouse pointer is no longer synchronous with its click position. For example, when clicking at the desktop and dragging the mouse to open a selection range, the square that is drawn is located above and right from the mouse pointer itself, showing the erroneous offset.
Does anyone have an idea how to solve this? It's depressing having to disable the 3D support under Linux all the time.
