Comment 6 for bug 1507676

Well then hopefully you can get it so this change to modesetting can be reverted & one isn't forced to get screen to sleep then awake.
My whole point was that this report is claiming that the switch from Intel to Nvidia fails which is not true is any respect.
It's purely a matter of no visible display until the display is put to sleep, the awakened

If the bug reporter had walked away from machine for 300 sec.'s, then pressed a key or moved a mouse they'd have gotten a visible working session under nvidia.

examples, ect. where in prior reports -
