Yes, you are right. But flickering (CPU related) appears even on a X1300 Mobility.
In git you can find several bugfixes due to the flickering/blanking problem (http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/log). But I don't know which fix handle your problem. Give it a try. -- X1200: flickering after update on Jaunty https://bugs.launchpad.net/bugs/331522 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
