Video setup on Flower Power iMac
iMacs with 500MHz, 600MHz, and 700MHz processors, the so called Flower Power models, have a 750cx version CPU and ATI Rage 128 Pro Ultra video controller. After a normal Edgy alternate CD install, video response is extremely sluggish. For example, mouse cursor movements lag several seconds behind physical mouse movement.
A fix is suggested in http://ubuntuforums.org/showthread.php?t=191080. It consists of the following changes to /etc/X11/xorg.conf:
- in the Module section
Section "Module" # Load "i2c" # Load "bitmap" # Load "ddc" Load "dri" Load "extmod" Load "freetype" Load "dbe" Load "glx" # Load "int10" # Load "type1" # Load "vbe" EndSection
- in the Device section
Section "Device" Identifier "ATI Technologies, Inc. Rage 128 Pro Ultra TR" Driver "ati" Option "UseFBDev" "false" Option "SWcursor" "true" Option "ForcePCIMode" "true" Option "XAANoOffscreenPixmaps" EndSection
The normal way to apply these changes is
- CTL+ALT+F1 to use a virtual terminal (command line interface)
- login as oem
- command: sudo /etc/init.d/gdm stop
- edit /etc/X11/xorg.conf, for example, sudo nano /etc/X11/xorg.conf
- modify the Module and Device sections as indicated above
- save the file and exit
- command: sudo /etc/init.d/gdm start
The normal Ubuntu login page should appear with much better video response
