[Bug 1028617] Re: Cursor shakes violently when connected to power source - makes touchpad cursor unusable
When i bought a new charger as the oringinal got chewed(stupid dog) i
noticed my mouse started to shake but wasn't quite as bad as that, well
sometimes it was unusable and quickly figured the charger was causing it
as it stopped when taking it out, haven't found a actual permanent
solution... but..
what i found that made it go away is making sure the charger wire and
everything as straight as possible, well not having to be straight but
the wire not meeting/touching at all itself at all.

Title:
Cursor shakes violently when connected to power source - makes
touchpad cursor unusable
Status in xserver-xorg-input-synaptics package in Ubuntu:
Incomplete
Bug description:
Using Ubuntu 12.04, 64-bit version, installed on Lenovo X220 laptop.
Fresh "default" install and settings configuration.
When the laptop is plugged into a power source, the touchpad's
onscreen cursor (the white arrow that shows position) shakes
excessively when trying to use the touchpad to control the cursor. The
shaking is so bad that it essentially makes the touchpad unusable. For
example, trying to click the minimize button in a window's upper left
corner will routinely result in accidentally clicking the close button
because of the cursor's shaking.
The problem is NOT present when Ubuntu is running on battery. But this
means I can never have Ubuntu plugged in and charging while I use it,
which is very inconvenient at times.
I'm using the power block and cable that came with the X220. But I
also tried using a larger power block and cable that came with another
Lenovo model - this power block is approved for use with the X220 and
is sold on the Lenovo website as an X220 accessory. But this larger
power block did not improve the shaking behavior either.
I have no special settings enabled for the touchpad. But changing the
settings has no effect on this shaking behavior either. I attached a
screenshot of my Touchpad settings [please excuse the HUD's presence -
I cannot get the HUD to NOT appear when I press ALT+PrtSc to take a
screenshot (I guess this is another bug)].
