From nouveau to nvidia and lost monitor
by Stragonian from LinuxQuestions.org on (#5AG90)
Greetings
I recently switched from using the nouveau to the nvidia drivers, and now the only way I can get my top monitor ( smart TV LG 43UJ6200 ) to detected is by unplugging the DP-1 cable in the back, and plugging it back into the card.
When I used the nouveau drivers the LG 43UJ6200 would detect the signal and turn on during the boot, when the nouveau driver would modeset while booting in the terminal.
Both the top and bottom monitors would then display cloned screens, until I logged in, and typed startx at the terminal, at which time I had an xrandr command that would automatically set the monitors in their orientation.
DVI-I-1 as the primary display at the bottom, and the LG 43UJ6200 as the secondary display on top.
Code:xrandr --output DVI-I-1 --primary --mode 1920x1080 --pos 0x1080 --output DP-1 --mode 1920x1080 --pos 0x0Now I have to crawl under my desk, and unplug the DP-1 cable and plug it back into the video card in order for the LG 43UJ6200 to detect a signal, and work.
