I'm trying to make it possible to switch between my integrated (Intel HD) and dedicated (ATI HD 5650) graphic cards. This should be possible with vga_switcheroo in kernel 2.6.35+.

Looking at /boot/config-2.6.36-0.dmz.13-liquorix-amd64 it seems that vga_switheroo is enabled "CONFIG_VGA_SWITCHEROO=y", but it still doesn't seem present in /sys/kernel/debug/

:: Code ::
$ ls /sys/kernel/debug/vga_switcheroo
ls: cannot access /sys/kernel/debug/vga_switcheroo: No such file or directory


Any help?

It could be that your system doesn't have two graphics cards. Could you post the output of lscpi in the [code] tags?

I'm pretty sure it has two cards :)

:: Code ::

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
01:00.0 VGA compatible controller: ATI Technologies Inc Redwood [Radeon HD 5600 Series] (rev ff)


I'll try reinstalling the Debian once Squeeze is released officially, hopefully it'll work then.
