This bug seems to be a bandwidth problem. When set to 800MHz the DRAM frequency is at 160MHz. Everything above 800MHz sets DRAM frequency to 320MHz (see http://www.linux-phc.org/viewtopic.php?f=6&t=46). So here is my little workaround:
Install sysfsutils. Then edit /etc/sysfs.conf: devices/system/cpu/cpu0/cpufreq/scaling_governor = ondemand devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold = 20 devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate = 620000 -- [X1250] screen flickers when CPU is at low frequency https://bugs.launchpad.net/bugs/351291 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
