The PC cannot 'see' the monitor. I've tried activiating the port, and tried installing the Nvidia driver for the card I have.
PC nr 1 cannot connect to 2nd screen through HDMI port. PC 2 cannot connect through display port (DP to hdmi cable)
HDMI cable works and is tested with work's windows PC.
Main PC I am trying this on has no hdmi port, only display port connecting through a dongle thing to convert to hdmi. All output and errors are from this PC, specs below, but worth mentioning that i also have a second PC with an hdmi port, same version of Salix v14.2, that acts the same way. Both are HP laptops.
HP Elitebook 8740w dual core.
Graphics card: NVIDIA Corporation G92GLM [Quadro FX 2800M] (rev a2)
Driver I am trying to use is 340.107 (correct according to Nvidia and also I had this working on Bodhi Linux so I know it works with this card).

So i read somewhere that maybe it's nouveau that can't see the ports (this makes no sense as clearly xrandr is listing the port as disconnected while using the nouveau driver). But I tried installing the nvidia driver anyway because why not?
The driver fails to install (I'll add here that i don't care much for nvidia and would just as well have this working with nouveau) but anyway, here is an excerpt of my log file for the error:
Code: Select all

In addition, the installer at the time it ran (yes, I ran it twice) displayed an error about kernel not being built with the correct version of GCC/G++ and another error about not having installed at the time of driver install the the correct version of same. So I downgraded to the version it said (5.3 from 5.5) but that didn't remove the error, and anyway I have no idea how to build the kernel module again using the old version of GCC that updates with system updates (potentially breaking it again?).
Needless to say, given that nvidia wrote a log file hundreds of lines long, refer to it for error reporting when the install fails BUT THEN DON'T INCLUDE THE ERROR IN THE LOG FILE, has me wanting to stick with nouveau
Sooo, how can i get my display port via converter dongle to hdmi to use my HD monitor?
Thanks in advance.
