Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
YOU did it super awesome Salix forum people! Thanks @gapan & @galmei !
Having upgraded the kernel packages as in my previous post I was able to install the nvidia driver and now the monitor shows up no problem.
Only thing to do now is to straighten out the resolution, the monitor is 4k but it's showing up max res as 1920x 1080 (laptop is 1920 x 1200).

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
Is the output of xrandr still the same, or does it now include something that looks like a higher resolution? If so, you could try
It may also be worth rebooting with the monitor connected (or try plugging it in after booting, if it was connected before).

A further thought (from the xrandr man page, see the EXAMPLES section at the bottom) would be to define your own output mode, if indeed you are not seeing it:
However, there must be some reason xrandr can't detect the monitor's correct resolution.
The other values needed to complete the line can be determined using cvt:
https://wiki.archlinux.org/index.php/xr ... esolutions
However, when I try that, the first value I see (refresh rate) is much higher than what xrandr is using, you may do better to try with 60 first.
Code: Select all
xrandr --output LVDS-1 --mode XxY #replace X and Y with the new values from the output

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
Hi, the outpuf xrandr now is:
That's very unlike the output in my first post in this thread. However, the highest resolution is the same as the laptop screen (1920x1200) on both screens.
Same for DP-0.
then I tried, from this Ubunti forums thread ( https://askubuntu.com/questions/377937/ ... resolution ) This failed on the last step, btw..
and that output this:
I then used that modeline output to input this:
and there was no output from that, so we can assume it had the desired effect.
Whoops, that wasn't meant to happen...
The last step in that process was to ceate a little script to make it persistnet, but I still get
so no point in writing a script that will fail every time.
Trying this also:
I'll look at the links from minosa when I get a chance. Will report back
EDIT I looked up the specs for this graphics card and got this from one site "DisplayPort up to 2560x1600, DVI/HDMI up to 1920x1200" so maybe this old card released in December 2009 doesn't support 4K, which at the time of release was science fiction.

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
I don't really have any further ideas at this point but just to clarify ... "4k" was meant to stand for whatever the output is you have connected the 4k monitor to, which seems to be DP-0. It's important when adding the custom mode to carry out the three steps in the right order: create it, "add" it to the right output, then select it for that output.
But it looks like this isn't helping because the correct resolution is somehow prevented from being "available" for the monitor, which is presumably why xrandr can't see it.
gapan will probably be more help when he passes by next!

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
That's easy to determine.So, which one is it? LVDS-0 or DP-0?
One turn off monitor and computer. Then turn both on again and boot. If everything is up, execute the following command:
Code: Select all
xrandr | grep -e " connected [^(]" | sed -e "s/\([A-Z0-9]\+\) connected.*/\1/"

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
Yes, sorry, LVDS is my laptop's built in screen and DP-0 is the external (well the port to it at least).
I don't think the monitor reports it's resolution back to the PC. When I used my job's Windows PC I had to manually tell Windows the resolution, it wasn't recognized there either, but I was able to enter it.
I'm going to have to take break from this until I have more time next week.

Re: Nvidia driver istallation woes (or no displayport / hdmi signal)
The monitor will report its EDID on request. For Windows, however, the monitor must first be installed in the Windows-specific manner before the responsible "Plug and Play Monitor" driver can take over this task. And something tells me that you haven't installed.chris_alife wrote: ↑18. Dec 2018, 20:43I don't think the monitor reports it's resolution back to the PC.
