I use linux Mint 18 Sarah MATE 64-bits.
I'm struggling with screen resolution. I installed Mint on September and until today it recognized my screen resolution (1600x1200) perfectly, but this morning it did not recognized it and I am trying to solve it. Now, the maximum resolution I can set is 1024x768. I have a NVIDIA video card, so I tried to change the controller from xserver-xorg-video-nouveau (default) to nvidia-340, but didn't gain much resolution, not 1600x1200 as I need (and always had).
Looking at many forums, specially this: https://community.linuxmint.com/tutorial/view/877, I've done so far:
cvt 1600 1200 sudo xrandr --newmode "1600x1200_60.00" 161.00 1600 1712 1880 2160 1200 1203 1207 1245 -hsync +vsync sudo xrandr --addmode DVI-I-1 1600x1200_60.00 sudo xrandr --output DVI-I-1 --mode 1600x1200_60.00
At this point, the resolution changed pretty well (it does not fit the screen, but I guess it has a solution). But, as this change is attached to the session, I need to keep it after a reboot, so, following the tutorial, I pressed Alt+Ctrl+F1 and in the terminal wrote
sudo service mdm stop
came to terminal with Alt-Ctrl-F1 again, and wrote
sudo X -configure
to generate the file xorg.conf.new, as the forum says, but, after restarting mdm service and log in, the file is not created. I still don't know how to copy the output and paste is here, but the last thing it says is No device to configure
