Very new linux user here (3 days experience).
I have 2 screens, that i have setup properly, not without having to fiddle with the little visual tool provided by default with elementary OS (screen positioning can have a tendency to go all over the place). They have 2 different resolutions.
On startup, my secondary screen won't start, as if with bad resolution. I then have to go into the tool (which displays the right resolution - super weird), then take a lower one, apply, and go back to the right resolution, which works (and still, i have to fiddle a bit with the positioning of the screen for some reason).
Graphics Card: NVIDIA GK104 [GeForce GTX 760 OEM] Display Server: x11 (X.Org 1.19.6 ) drivers: nouveau (unloaded: modesetting,fbdev,vesa) Resolution: firstname.lastname@example.org, email@example.com OpenGL: renderer: NVE4 version: 4.3 Mesa 19.0.8
Hope that it will be a good enough description, i am really just getting started ^^.
