Inconceivable :)

The first while loop should enter that condition twice, for these two devices:

00:02.0 VGA compatible controller [0300]: Intel Corporation 4th Gen Core
Processor Integrated Graphics Controller [8086:0416] (rev 06)
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208M [GeForce GT
730M] [10de:1290] (rev a1)

The second while loop should not have any effect since you don't have any "3D
controller" devices. Can you double-check that the first while loop never
executes its body? (e.g. put a print before/after/in it, which will confirm
that your code is actually being executed and that it never goes inside.)
