While I do like my Gazelle a lot, to add to the GPU issues: It is capable of running 2x 3440x1440 with the internal screen on, but not if one of them is used vertically. As in, it will work, just not rotate. Once you close the lid (and disable the internal display), it suddenly works. That is something that just amazes me. Does it take that much more GPU power to run a large screen rotated 270 degrees?

Maybe it's reserving resources for the total 'bounding box'?

So 1920:1080 + 3440:1440 + 3440:1440 => 8800:1440 (12,67Mp)

But 1920:1080 + 3440:1440 + 1440:3440 => 6800:3440 (23.4Mp)

EDIT: with the laptop screen off, it would just be:

3440:1440 + 1440:3440 => 4880:3440 (16.8Mp)

In any case, this seems to be an actual GPU issue instead of an issue caused by the laptop's design. Something that would happen with any laptop using that nvidia card.

My boss is a Linux lifer. The kind of guy who compiles his own kernel and knows this stuff in and out. I mentioned that I got my first Linux machine to him and that it had an integrated GPU. First thing he said to me was "that was a mistake". From what I've seen I would agree. My machine is way glitchier when I enable the Nvidia GPU. If I had the option to run multi monitors without it on, I'd probably never use it save when gaming.
Could this be fixed with xrandr?
