Re: Display Problem with PelicanHPC v1.8 64bit

Phew, I finally got my graphics card to work. I messed around with the xorg.conf file for the last few hours until I figured out what to do. If you have an ati graphics card there are a number of drivers that ati can use.

In the Device section of the xorg.conf file, if you specify the driver as "ati", the correct driver is meant to be chosen. The "ati" driver is really a wrapper for a collection of drivers, and the wrapper is meant to choose the correct one for you.... not the case.

I ended up trying the other relevent options {radeon / radeonhd / r128 / atimisc} along with a rake of other options including {vesa / vga / chips......}

In the end, it turned out that the correct driver for the Ati FireGL 7350 is radeonhd.

There's no need to change the xorg.conf file by hand, you can specify the driver when booting using a cheatcode. Of course, you may want to change the display modes available, in which case you'll have to change the file.


boot: live xdriver=radeonhd


One problem down.... a few to go!
