[Bug 1409133] Re: Heavy black flickering in mir_demo_server

 

Not sure if this will help much, but when I downgraded to Mir
0.9.0+15.04.20141125-0ubuntu2, the mir_demo_server_shell works again
(feels a bit slower than before though for some reason). So I guess the
problem isn't with the kernel I booted.

Also, these are my video card details:

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller])
	Subsystem: Lenovo Device 215a
	Flags: bus master, fast devsel, latency 0, IRQ 26
	Memory at f2000000 (64-bit, non-prefetchable) [size=4M]
	Memory at d0000000 (64-bit, prefetchable) [size=256M]
	I/O ports at 1800 [size=8]
	Expansion ROM at <unassigned> [disabled]
	Capabilities: <access denied>
	Kernel driver in use: i915

Title:
  Heavy black flickering in mir_demo_server

Status in Mir:
  Incomplete
Status in mir package in Ubuntu:
  Incomplete

Bug description:
  After running mir_demo_server on VT 1, when I switch to VT 7 then back
  to VT 1, the demo server really flickers black quite a lot (entire
  screen, pointer included). I'm not sure, but I also upgraded my kernel
  to 3.18.2-031802-generic at the same time, if it's because of that,
  please mark invalid.
