The radeon.new_pll=0 kernel line works on my ATI X1600 (HP nc8430 laptop). The 3d and desktop effects are not working with this trick.
Strange thing is: If I use my TFT monitor as a second screen in a dual head setup and don't use the kernel line, the laptop screen is ok. TFT monitor is not ok, shows horizontal scrolling. So I disabled my second screen, and now the laptop screen is ok (with 3d effects/compiz). -- [RV530] video problem flicker unreadable hp compaq nx9420 ati radeon [Needs pll quirk] https://bugs.launchpad.net/bugs/537640 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
