Installing ATI graphics drivers on OpenSUSE 10.2

To get 3D graphics acceleration on ATI Radeon X1xxx series graphics cards, ATI’s proprietary driver must be installed. Ideally, it should be a simple exercise: download the driver from ATI and follow their installation instructions. However, using the automated installer, I got error messages saying file atiogl_a_dri.so could not be found. Installation reported successful completion, but although the fglrx driver was installed and everything was OK in 2D, there was no 3D acceleration.

The correct way to install the ATI driver is documented in the ATI HOWTO. Basically, you have to build a distribution-specific package and then install that using rpm. At the end you should have full 3D acceleration as witnessed by running fglrxinfo:

ckm@zeus:~> fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon X1400
OpenGL version string: 2.0.6400 (8.35.5)

Check that you get the same result both as root and a normal user. If you get permission problems with a normal user, edit /etc/X11/xorg.conf, find the section labelled “DRI” and change the Mode line to:

Mode 0666

Save the file and restart X.

    Hi, I’m with you until I run fglrxinfo, where I get an error when logged in as myself and root. I’ve got a question on a support forum about it, but if you could have a look as well that would be great – I’m desperately in need to be in my LCD’s native resolution and afaik the ATI drivers are what is holding me back.

    Thanks! 😉

  2. Hi Chris,
    Are you using a VGA or DVI cable to connect the monitor? Try switching to the other type and install the ATI driver again.

    Although not entirely related, I did once have a problem getting a flat panel display to work at the correct resolution. After exchanging the DVI cable with a VGA cable it worked.

    I doubt that the 9100 should be limited to 1600×1200 when the specs also say that it supports up to 2048×1536 @ 32bpp resolution.

    I hope you find a solution.
