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
