I can confirm that the workaround documented by techneeq resolved the issue on my Evo N410c. I created an xorg.conf file ("boardname" automatically identified as "Radeon Mobility M6 LY"), uncommended the "AccelMethod" option and defined its value to be "EXA". FYI if you are running Gnome, you will want to use "service gdm stop" and then "service gdm start" to to control the desktop manager.
Now running with visual effects set to "None", I have a usable system monitor and the system notification popup boxes are legible. I tried changing the visual effects to "normal", but my system locked-up. For an old junker of a laptop I can live (happily) without the visual effects. Thanks goes to techneeq for hacking a solution and sharing it with the community. -- System Monitor display is corrupt after upgrade to 9.10 https://bugs.launchpad.net/bugs/466066 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
