I have a Sony Vaio VPCSB1D7E (W7 + Ubuntu 12.04). It has hybrid graphics (AMD+Intel). I installed both the AMD Catalyst drivers and the Intel ones. So far, using both graphic cards works fine, but I have a problem when using the Intel card.
I cannot properly shutdown my laptop when I select the Intel card. It actually works well when using it. Then, when I shutdown the laptop, the console appears showing the shutdown process and stops in the line "shutdown laptop mode". Then, I have to long-press the shutdown button to switch off the laptop.
This only happens when using Intel's card, not AMD. Please let me know what appropriate logs would be useful to try to solve this problem.
Thanks!
