Public bug reported:
Symptoms:
On login, the desktop takes a long time to load, and when it does, everything
blinks. It is possible (but difficult) to open a terminal and execute commands,
through the right-click desktop menu.
I first noticed the issue in mid-July of 2018.
System:
Acer 5100
Ubuntu 16.04 (64-bit)
Graphics card: VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RS482M [Mobility Radeon Xpress 200]
Possible red herring:
Believed to be mesa-related, as symptoms very similar to bug #1741447, which is
a duplicate of #1735594. I have been informed by a mesa developer that it is
different because that bug affects Intel GPUs. This system has a Radeon GPU.
Ubuntu reports it as a Compiz issue, so best to begin from there?
I have attached a log that may be helpful.
Many thanks for any help.
