Public bug reported:
The Screen flickers during boot up and System runs very slow.
This is my GPU info.
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
ProblemType: Bug
DistroRelease: Ubuntu 18.04
Package: xorg 1:
There is only one PLL (Phase Locked Loop) in the processor, all CPUs get
the resulting clock. When they go into deep idle states (deeper than C1,
at least for my processor) then they give up their vote into the PLL as
to what the frequency should be. Your single 100% task is dedicating the
CPU freq
Does install the suid-root wrapper allow for any user to run an X
server? This seems a little too open if so, as it seems better to allow
only either root, or the user logged into the console to run the server,
IMHO.

@Doug Smythies: thanks for the reply.
I'm sampling every second.
Anyway, just to better understand.
When my system is idle all cores spend in C0 less than 10% of the time and the
frequency of each core reported by i7z is different and below 2.2GHz. When I
run a single core (and single thread) ta

@Davide Sangalli: What you describe and show in your comment #80 is
correct and exactly what should happen. Your processor is spending an
extraordinary amount of time in C1 as opposed to deeper idle states. At
what sampling frequency do you run i7z? I would suggest once every 15
seconds or so, so t
I also mention that, monitoring with i7z the clock of my CPU, when intel turbo
is not working I get different freqs for each core

A bug report was filed in 2010, supposedly fixed in 2018 and patched in
2019 in `xrandr` version `1.5.1`. I tried compiling `1.5.1` in Ubuntu
but it didn't seem to have been fixed yet. Documented in this Ask Ubuntu

Ubuntu?](https://askubuntu.com/
