Then find the module-assistant, fglrx-driver and fglrx-kernel-src and tick them and install them. Build and Install the Module Code: Select all module-assistant auto-install fglrx-kernel-src I believe this compiles form source the fglrx-kernel as well as the a bunch of other stuff including the fglrx-driver. I noticed also that linux-image-2.6.26-1-486 was downloaded, I assume this is pulling in dependencies as I am running linux-image-2.6.26-2-686. Update your xorg.conf file (still as root) Code: Select all aticonfig --initial Restart for the changes to take effect. I noted that I could boot into linux-image-2.6.26-1-486 or linux-image-2.6.26-2-686 though only the latter gave me my full 2 Gigs of RAM (so that is the one I boot into). Confirm the Installation Now that you have rebooted you can test to see if the restricted driver is enabled by doing (as non-root); Code: Select all fglrxinfo
