I have tested Workstation (x86_64) TC3 and TC4 on my HP laptop with
dual graphics (Intel and AMD):

00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) (prog-if 00 [VGA controller])
Kernel driver in use: i915
Kernel modules: i915

01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series] [1002:6760] (rev ff) (prog-if ff)
Kernel driver in use: radeon
Kernel modules: radeon

While both TC3 and TC4 exhibit the flickering screen bug[1] at login,
neither fails to display the GDM screen, leaving the machine stuck at a
black screen as described in the bug under test.

As such, I'm not going to comment on Bugzilla with a useless "didn't
affect me", but if there is any data I could collect from this working
dual-GPU system that would be beneficial please let me know. The laptop
in question is a test machine, so repeated clean installs are no
problem.

Replying through a copy-paste, so apologies if this breaks somebody's
threading.
