- Tested on Ubuntu 14.04, 16.04, 17.10, Debian 8, Tails (0.2,...,6.2), Kali... and some other Linux distributions.
2) The computer is a Dell laptop with a built-in NVIDIA Quadro FX 2500M (identified as NVIDIA Corporation G71GLM)
3) Kernel driver in use: nouveau
4) Everything was worked fine using the nouveau driver but someday the screen backlight failed and I have to replace the broken WUXGA+ screen with a new one, same specifications except is a glossy screen (not matte). The screen product numbers are almost identical (New screen: Samsung LTN170U1-L02, Old one: Samsung LTN170U1-L01).
5) With the new screen installed the display is corrupted as it shows in the attached pictures. The vertical resolution (1200px) seems to be fine but the horizontal pixels (1920x) are distributed doubling the width (the right half out of the screen). The desktop is chopped and the screen is full of scan flicks, errors and artifacts.
6) No issues using NVIDIA propietary driver.
