Dan Smith, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1404332 Title: Touchpad cursor loses precision after VGA monitor plugged in Status in xorg package in Ubuntu: Expired Bug description: I just plug in the VGA cable. The external monitor is detected acc.to dmesg. A USB mouse works OK. The problem lies somewhere with synaptic driver. If I simply put down a finger on the touchpad and hold it still, the cursor still fidgets in random directions by a couple millimeter increments.
