Description Wim Goeman 2012-02-26 14:00:43 UTC 
Hello,

I have a setup with intel graphics combined with Radeon graphics. Whenever I try to use the vga_switcheroo system to switch graphics my system completely freezes. I can switch off the GPU not in use, but can not actually perform he switch.

The freeze does not provide any report, just nothing happens anymore.

More details about the problem can be found in the bug report on launchpad:

Thanks for looking at this.

I have an update for this one. As I switch to Fedora, I decided to try the same there, without success (f16)

Timeout, closing. If the problem persists with recent kernels, please reopen.
