Public bug reported:
After a recent update (kernel?), I have begun to occasionally receive
the message "Running in Low Graphics Mode" at boot (maybe half the
time). I can tell it to use Default setting from the options it offers,
and get by it, after which things look and work normally until a reboot,
which may or may not occur correctly.
I also usually get "System error detected, Report? at the same time, so
I agree to report it.
Please note that I'm using 16.04 (fully updated), Gnome Flashback
Metacity, with [AMD/ATI] Cape Verde PRO [Radeon HD 7750/8740 / R7 250E]
. This problem shows up no matter which of the above I'm using, or
Unity.

I have found a WORK-AROUND. Using x-diagnose, I selected all options
under both Debug and Workarounds. After this, all works normally every
time. However, I take this as a crutch, not a fix, and think other
action should be taken
Selecting "View Errors" shows no errors, so I never tried reporting from
that point.
This gives me a presumption that there is a bug in coding that interacts
badly with my system and a few others like it, which I encountered in my
search for a solution.
Also, if I simply go to 18.04 (I don't really want to just yet.) will it
likely fix this or might this block or damage the upgrade?
