I'v had some similar problems in a ATI radeom Mobility X1400 [rv515]. For me the problem was during a guest or second session. [my whole screen would shiver in a guest session] If i used the new_pll=0 quirk the new_pll=0 the problem was delayed for ~6hrs. After which i would notice the problem again.
+ I had additional problems where when system was running for long hours , the memory usage was a bit high [gem objects unrelated] and CPU usage by Xorg would spike with wallpaper changes .. and a couple of other problems where Xorg CPU usage would spike. I installed mainline kernel .33.3 from > http://kernel.ubuntu.com /~kernel-ppa/mainline/v2.6.33.3-lucid/ And I'm not having any problems now. I dont used the new_pll=0 even. Several problems i was having are solved too. -- [RV515] [LENOVO T60] external screen display shows "shivering", horizontal refresh offset https://bugs.launchpad.net/bugs/541501 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
