I am trying something new : since the machine is using Wayland I have
removeed the following package that was installed by default (as
[installed,automatic]) :
xserver-xorg-video-intel
Seen on the following post that it could help :
https://forums.debian.net/viewtopic.php?t=149472
Will report
Since I removed xserver-xorg-video-intel
The screen still flickers but seems to happen much less often.
Jun 3 00:03:34 pluton kernel: [ 205.129238] i915 :00:02.0: [drm]
*ERROR* CPU pipe A FIFO underrun
Seems to happen a few minutes after rebooting. Then it is very rare.
Does removing that
Currently I'm using the machine with the psr_enabled=0
But I still see the screen flash from time to time. Every time the screen does
flash the following line appears in my /var/log/syslog :

Been able to get "some" kind of colorless picture using guvcview
So camera seems to be working
But there are almost no colors, and default settings produce a very
dark, useless content.
The attached screenshot was done using the following setrings in
guvcview :
Saturation : 19
Contrat : 64

A new firmware has been pushed for the machine (new version is 4.17) with fixes.
I think the fix about the C-States is probably the one that should reduce, or
eliminate, that flickering problem from the i915.
Upgrading and will report in a few days about improvements, if any.
StarLite MkIV:
Screen flickering gone with latest firmware update :)
** Changed in: linux (Ubuntu)
Status: Confirmed => Fix Released
