3.2.0-17.27 seems to fix rc6-related graphics problems also on my machine: Lenovo X220 Version: 8DET54WW (1.24 ) 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09)
With previous kernel, 3.2.0-17.26, I had occasional graphic glitches. Glitches appeared as unrefreshed screen areas (displaying content from windows below the top one). Now they are all gone. Power levels have remained at the same level (avg=6.67W, std=0.11) in idle mode. Well done! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935965 Title: RC6 enabled causes severe graphics corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/935965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
