I've spend the last couple of months poking around this issue, deploying workarounds and whatnot. Loaded up the beta and I can't seem to fix something that I think is supposed to work.
On 11.10 I cannot get the fglrx driver to work while the laptop is in Switchable Graphics mode, despite the driver's (and internet's) claim that it works. Laptop boots and installs fine, defaulting to the Intel GPU. I'm prompted by "Additional Drivers" to install fglrx. If I install and reboot everything still works, but the Intel chip is still used. If I do the initial config "amdconfig --initial" I get the following message:
Found fglrx primary device section
Powerxpress error: Cannot stat '/usr/lib64/fglrx': No such file or directory
Failed to initialized libglx for discrete GPU
Saving back-up to /etc/X11/xorg.conf.fglrx
After that if I reboot the laptop hangs before LightDM, the last text on the screen being "checking battery state." I'm pretty sure Powerxpress is what I need so I don't have to set the graphics chip in the BIOS.
Has anyone else seen this and know of a fix or should I file a bug report because something (not me) is really broken?
Lenovo T500 laptop
Ubuntu 11.10 Beta1 64 bit.
GPU1: Intel Mobile 4 Series Chipset
GPU2: ATI Mobility Radeon HD 3650
Any help is appreciated.
