switching off GPU

Postby agvares on Tue Feb 12, 2013 4:39 am

Like many users with hybryd video (I have ATI and Intel on my laptop), i've tried to solve the problem by making proprietary drivers actually work, but failed at that (changing between GPUs causes mess in x-server configuration)

so, unable to tolerate all the fan noise and excessive heating, i've decided to just switch the ATI GPU off (not that I would really need it)

i've done that by editing /etc/rc.local file, i've added two lines before exit 0:

Code: Select all
chown -R $USER:$USER /sys/kernel/debug
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch


everything works great, even sensors command indicates the temperature of radeon PCI adapter as -128*C

the only issues is, that works only after a reboot. if I just close the lid and my laptop goes to hybernation, whenever it wakes up, radeon apater is back to life again at +38*C

not that it is as loud and problematic as it was before the rc.local fix, but the fan is really annoying.

so, the question is: are there any ways to keep radeon GPU switched off after waking up from hybernation?

thanks in advance
