Public bug reported: If using the touchpad, the cursor jumps around on the screen. It seems to me that there are also some events (like clicks) that get fired. This issue can be worked around by disabling and enabling the touchpad (pressing Fn+F7 twice) but it will reappear after a certain amount of time.
I have already tried to use some mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D. I have tried v3.18-rc2-utopic, v3.18-rc1-utopic and v3.17.1-utopic. Either I could not boot into the specified kernel or the bug still existed. If there is any more information I could give or any debugging work that I could do, please let me know.
