 Posted: Sat Jun 07, 2014 5:00 pm Post subject: [solved] vgaswitcheroo vs grsecurity |
 |
|
I'm trying to setup vgaswitcheroo to disable radeon videocard in my laptop. It definitively can be done on this machine, because I did it before with Debian (and I vaguely recall that I did it also on gentoo few months back). Anyway now I have a problem with it.
Probably I forget about something, but there's no vgaswitcheroo under /sys/kernel/debug in the firstplace.

This problem (no vgaswitchroo in /sys/kernel/debug) is related to hardened kernels.
On gentoo-sources and vanilla-sources everything works fine 
Here's the diff of gentoo-sources and hardened-sources configs:

Apparently problem is caused by grsecurity patch. Unfortunatelly not by any of its options, which can be set 'on' or 'off' in menuconfig.
I patched (by hand) vanilla kernel-3.14.6 with grsecurity patch, but I disabled Grsecurity completly in menuconfig - and problem still occurs.
I wanted to try older hardened-sources which use stable grsecurity patch , namly 3.2.60. But when I boot there's this error related to disk encryption (it occurs after password was typed in):

I compared boot logs of vanilla-3.14.6 (on which vgaswitcheroo is present in /sys/kernel/debug) and vanilla-3.14.6-patched-with-grsecurity (on which vgaswitcheroo is missing).
Interesting part is here:
