UPDATE: I installed kernel 4.16.7 from http://kernel.ubuntu.com/~kernel-
ppa/mainline/ and things get much better. Not as good as it was on 17.10
but largely usable. Some regression in the i915 driver must have
occurred in 4.15 and now it's catching up again apparently.

Title:
"Activation of network connection failed" popup
Public bug reported:
In Ubuntu 18.04, display freezes for ~1-5 seconds at seemingly random
intervals. When it resumes, gnome shell's dock flickers as if the
problem was caused by it.
ProblemType: Bug
DistroRelease: Ubuntu 18.04
Package: xorg 1:7.7+19ubuntu7
ProcVersionSignature: Ubuntu 4.15.0-20.
Public bug reported:
All network connections work normally, however the popup "Activation of
network connection failed" keeps showing.
ProblemType: Bug
DistroRelease: Ubuntu 18.04
Package: network-manager 1.10.6-2ubuntu1
ProcVersionSignature: Ubuntu 4.15.0-20.21-lowlatency 4.15.17
Uname: Linux 4.
Public bug reported:
When my laptop resumes from suspend, the secondary GPU (Radeon R7 M265)
does not work. Prior to suspend I can use it. After suspend, trying
DRI_PRIME=1 glxinfo | grep OpenGL simply fails (see attached file).
ProblemType: Bug
DistroRelease: Ubuntu 18.04
Package: xorg 1:7.7+19u
Public bug reported:
Desktop performance on my laptop (Intel HD 520, driver: i915) used to be
generally good on previous Ubuntu releases but on 18.04, there is a VERY
noticeable regression. Moving windows around in GNOME is choppy and
tearing. It gets dramatic after the laptop resumes from suspend
I'm having the same problem with real (physical) dvds. They used to play
fine in Ubuntu 13.04 and VLC plays them without problems as well.

I am having a similar problem and none of the suggested fixes worked for
me. It seems to be an ALSA-related bug as I eventually noticed that the
output from alsa-info is different before sleeping and after resuming
(see attached).
