Roger Davis, could you please provide undo the WORKAROUND, and provide the missing information from https://wiki.ubuntu.com/DebuggingKernelBoot ?
** Description changed: 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] - .
