Message-ID: <1328574087.2955915.1308635991553.JavaMail.fmail@mwmweb001> (raw)
Hi Folks,
ok, I'll give it a try this evening. Just one more thing: Should I pass enable_rc6 as a boot parameter like this: "i915.enable_rc6=0" or is it set by echoing sysfs (/sys/module/i915/parameters/...)?
regards, nico
