Re: Detecting ATI Radeon 7500 (PCI version)

I thought I would try the very latest verion of X (4.2.1), and after 
installing, it works!

Just to be sure,  I added the options previously mentioned.

However, the display isn't the best.

The first thing is the resolution. Checking the X server settings in the GUI 
lists the dimensions at 1920 x 1140 (the maximum capability of the monitor) 
and the resolution at 135 x 135 dpi. How can I get this to display at a 
reasonable setting , such as 1152 x 864?

Also, the background/desktop is very "noisy". Put another way, the color of 
the background looks like it has patches of smoke through it. Obviously, 
this doesn't affect pure white or black colours, but all other colours are 

Can anyone share some insight into some settings I may need to turn on or 
add to the config file?

I have attached my config file.
