Does the problem occur if you log into an "Ubuntu on Wayland" session? I
am wondering if it is specific to Xorg sessions.
** Summary changed:
- my displays jump to the right occasionally
+ Thunderbolt displays jump to the right occasionally
** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu)
** Changed in: xorg-server (Ubuntu)
Status: New => Incomplete

Title:
Thunderbolt displays jump to the right occasionally
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
I have two monitors connected to my Dell XPS 13 via the USB-C output.
For the majority of the time, it works fine. Occasionally, one or both
of the images on the displays jump to the right, so that the right few
inches appear on the left.
To rectify the problem, I run the 'displays' app, move one of the
displays a little, click 'apply', and then, instead of 'keep
settings', I 'revert' them to their original, and then everything is
fine for a while.
