> The specs:
> Asus x56tr Notebook
> AMD TURION X2 64
> ATI 3200 & ATI HD3470
> RAM 4GB

> I can install Intrepid Ibex, but my graphics cards don't work in Intrepid.

> Installing Ubuntu only works with the extra boot options acpi=off or MAXCPUS=1. Ubuntu Intrepid installed, but i couldn't get any GUI. The x-server tried to start but failed. I also cannot switch to terminal using crtl-alt F1, because X keeps trying. sometimes i get the errormessage: no screens found. I tried ati, radeon, vesa, radeonhd. I tried installing the official ati-drivers. Nothing worked, then after hours of mindbreaking i installed Hardy Heron, IT worked! Installed the restricted drivers and the screen looks nice. No sound though and no wireless.

> How can i get Intrepid Ibex to work? I read somewhere that xorg 7.4 could be the problem or the 4GB of RAM. Don't know how to fix this though. Latest versions of Mandriva and OpenSuse also do not run from livecd or install and suse complains about the graphic card.
