Hello! edacgck interesting edacgck site! I'm really like it! Very, very edacgck good!

Very nice site!

Post-Installation Checks

Verifying

Run the following command to check its output to ensure the fglrx driver is installed properly:

$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI MOBILITY RADEON 9600/9700 Series
OpenGL version string: 2.0.6650 (8.40.4)

The OpenGL vendor string should read ATI and not Mesa.

If you see a message like 'Xlib: extension "XFree86-DRI" missing on display ":1.0"' then you may have to add the following to /etc/X11/xorg.conf (see [1]):

File: /etc/X11/xorg.conf
Section "Extensions"
    Option "Composite" "Disable"
EndSection

Additional configure with aticonfig tool

You can even more configure the driver with the aticonfig tool, more information can be found at Configuring.

For example:

  • use powerplay option to switch power state for battery friendly or performance mode
  • use dual head or one big desktop mode
  • turn second monitor on/off on the fly


Ubuntu-specific Issues

Tocuhdwon! That's a really cool way of putting it!

If suspend is not working

If suspend stops working after fglrx installation, meaning display will not initialize after attempting to resume, then changing a few options has been reported to work for some hardware.


For ATI X700 and ATI X1100 on Acer Aspire 5051:

File: /etc/default/acpi-support
SAVE_VBE_STATE=false
POST_VIDEO=true
USE_DPMS=false

For ATI X1300 and the ATI X1400 on a Dell Inspiron 9400 or Lenovo Thinkpad T60, also for ATI X1600 on Asus Z96J (using install method 2):

File: /etc/default/acpi-support
POST_VIDEO=false
