I have the flickering with the radeon driver, a Mobility FireGL 5200 and dual monitor setup. The flickering was on latest intrepid (with backports repository) and still is there on an up-to-date jaunty.
I could correlate the flickering of my external monitor to screen activity. When I do nothing, the screen flickers almost not at all. When I move a window, or switch between virtual desktops, the screen flickers more often. When I run glxgears, the monitor stays blank until I quit glxgears. Also, disabling desktop effects improved my situation. With radeonhd, the screen does not flicker at all. So maybe this is related to 3D acceleration? -- Screen flickers or blanks every 10 s with KDE4 https://bugs.launchpad.net/bugs/278471 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
