Ever since upgrading to 16.04 from 14.04 on my Lenovo x230 the HDMI
output to a Benq W1070 is corrupted if run at 1920x1080 (native

I've tried to connect my Lenovo T460s to a HDMI projector using a mini

I have a Lenovo T460s and have upgraded to Ubuntu 18.04. To be able to

following:

After a clean reinstall of 18.04 this issue still exists. I did notice
something else though. The default settings are usable but they become
unusable with higher pointer speeds in settings. I end up preferring

Testing the wayland session the pointer behavior is quite different. It
requires a much smaller speed setting to be usable and seems more
erratic than the X one but maybe that just needs getting used to.

I have a X61 lenovo thinkpad with a dell 24 inch LCD attached in a dual

of its own output
By the way, this is a regression from jaunty where the same thing worked
fine. On the other hand resume is much faster now... :)

I'm not running compiz at all so this bug applies without it. The way
the problem is most easily triggered is by trying to change virtual
desktop when flash is already fullscreen. That seems to lock the screen

It did indeed seem to work properly without effects so this may very
well be compiz/unity's fault.
