[SOLVED] Slow GUI (Compiz) on Ubuntu 8.04 (Hardy Heron) using ATI Radeon X300 Mobility

Print this post Email this post

I finally managed to fix the issue as described in: Slow GUI (Compiz) in Ubuntu 8.04 (Hardy Heron) using ATI Radeon X300 Mobility

The solution revolves around:

  1. Download and install binary driver from ATI
  2. Remove the MESA driver
  3. Force aticonfig to renew the xorg.conf
  4. Make sure AIGLX and Composite is On/Enabled

Removing MESA Driver
Run the command:

sudo apt-get remove xorg-xgl

Run aticonfig
Run the command:

sudo aticonfig --initial -f

Check AIGLX & Compositing are enabled

  • Run the command:
    sudo vi /etc/X11/xorg.conf
  • Search for the keywords ‘AIGLX’ and ‘Composite’.
  • AIGLX should be under ServerFlags section and the value should be ‘On’
    Options AIGLX 'On'
  • Composite should be under Extensions section and the value should be ‘Enable’
    Options Composite 'Enable'
