Subject: [Bug 34252] Unexpected behaviour when switching video cards with vga_switcheroo

Either ignored, or DIS card should be turned off, not IGD. I don't know what
exactly should happen as there is seems no official docs for vga_switcheroo,
only various tutorials and wikis. For example ubuntu tutorial
(https://help.ubuntu.com/community/HybridGraphics) says:
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
Connects integrated graphics with outputs.
-- absolutely nothing is said if some card should be turned on / off.
