Public bug reported:
When using my Quadro K620 with the nouveau driver, the screen
scintillates. This is more perceptible on the SDDM login screen and when
viewing the desktop background. This does not happen when driving the
GPU with the closed NVIDIA driver.

Hi,
I had not used my laptop in a while and your message prompted me to
upgrade my packages and try again with a newer version before adding
more information.
The problem I described does not occur anymore now -- I tried with the
latest kernel 4.4.0-30-generic and with the latest tuxonice
Adding this in case it helps identifying what is going on.
Here is the upper part of a screen capture. The red dot is the position
of the mouse cursor at the time of the capture. Notice how the "g"s
above the y-position of the cursor have a glitch, but not the one below.

Public bug reported:
I just installed XUbuntu 16.06 on my laptop.
Suspend to RAM and hibernation seem to work correctly, but resuming from either
of it is not actually possible because the screen remains black. Concerning
hibernation, this happens with the default hibernation method as well as
Hibernation and resuming from it works fine with TuxOnIce (kernel
4.4.0-18-generic-tuxonice). This may help you find out what is causing
the problem with the default hibernation process.

It appears that booting with nomodeset prevents the radeon video driver
to load, so this driver may be the cause of the problem.
