I am trying to use the ATI Catalyst SDK 10.12 (fglrx) on a Ubuntu 10.10 environment. My laptop has an integrated Intel HD Graphics as well as a ATI Mobility Radeon HD 5450.
After installing the ATI SDK the computer crashes after reboot and I am only able to load X after deleting the generated xorg.conf file.
Ubuntu 10.10 comes with a utlity called vga_switcheroo to be able to control wich GPU to use (as explained here: http://asusm51ta-with-linux.blogspot.com/).
After reading several posts with similar problems, it seems like fglrx drivers doesn't support hybrid GPU's configurations.
So my question is if this is indeed the case or if it has more to do with the BIOS settings (my laptop doesn't allow me to switch off the integrated GPU).
