[Bug 1488719] Re: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
Running dell latitude E5450 with nVidea card and seeing this - both the error and sometimes when unlocking screen the monitor keeps flashing on and off every 5 seconds until you change the resolution and change it back.
The best way to do this is CTRL+ALT+F6 then CTRL+ALT+F7
I am also seeing the issue where X is not showing the docked monitors
(eDP) as active if I:
suspend -> undock -> resume -> suspend dock -> resume
apport is reporting crashes frequently (using the non free Nvidea driver
so I assumed this was the issue).
The bit of information I can add is that apparently Windows users are
effected by the screen flashing also (in a company so everyone has the
same laptop)!
Dell released a BIOS update to fix the flashing, but it didn't help.
Just wanted to add this as it may be a firmware issue.
