Thanks for taking the time to report this bug. To provide more detailed information can you please run this command on the machine that exhibits the bug: apport-collect 366858
Also, can you please provide the exact brand and model for the external monitor you're using? Looks like a Dell from the photo, but what is the model number etc? Finally, if you have access to another external monitor (of another brand/model) it would be useful to try that (to see if this happens only with that particular type of external monitor or if the bug happens with all kinds of external monitors for your graphics card). ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- screen not completely refreshed in multimonitor config https://bugs.launchpad.net/bugs/366858 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
