[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Philipp Grete <mail@xxxxxxxxx>

Fixes LP: #796030 by removing forced pipe A on HP 2730p.
Quirk has previously been introduced to fix a sleep mode problem that does not exist any more.

Fix has been confirmed by at least three people (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/796030) who didn't experience any sleep mode problems after applying the patch.
