Due to the fact that the privative AMD drivers doesn't work with this particular combination of GPU (muxed system) I am stuck with open source drivers and vga_switcheroo to choose between them. However since the upgrade to 13.04, I can't switch to the dedicated GPU as I could in 12.10. When I activate the AMD card and logout of the active session (in order to kill X, as needed by vgaswitcheroo), I can't get to lightdm and I get this message: "vga_switcheroo: client 1 refused switch" and "vga_switcheroo: client 101 refused switch". After this, the only option is to drop to TTY and restart the system. Also, possible related, when shutting down the notebook I get a lot of "atombios stuck executing... for more than 5 secs" errors. Both GPUs are working fine in Windows and, as said, used to work fine in Ubuntu 12.10.
