I have a new HP dv7 laptop with ATI Mobility Radeon HD 5650 graphics card, and also Intel graphics (switchable). I have done the following and want to understand what is going on with my graphics driver
- Resized windows 7 and did fresh install of 10.10
- Booted into 10.10 and things seemed to be working okay
- Enabled ATI graphics, and was clearly working on the ATI rather than Intel GPU (desktop cube worked)
- Rebooted, got an error that modprobe could not load modules.dep, and also something about i915 symbols
- Rebooted into recovery mode, modified xorg.conf to remove the mention of fglrx
- Rebooted, and the errors show, but then x starts but clearly in intel graphics
I would ideally like to be able to switch between the ATI and Intel graphics, a la vga_switcheroo. My first problem seems to be that the folder
/sys/kernel/debug/vgaswitcheroo
does not exist, hinting at some kind of kernel issue. What can I do to get this available?
Thanks!
