New X Screen Requires Restart...

Hey all,

EDIT to shorten this a bit...

Problem is I cannot enable any screens from my 2nd nVidia card which is actually my main card meaning I am stuck on tiny low resolution monitors not suited well for sorting this out.

I have tried changing /etc/X11/mhwd.d/nvidia.conf and making sure it's using that file which it is as I can break it ok lol.

But no matter what I do the screens on the 2nd GPU are out of reach.

Both cards are using the 440 Drivers, I have tried with the 335's too.

If I try to enable the screens in nVidia settings it just says New X Screen Requires Restart but it does not enable the apply button and does not do anything.

If I look in System Settings it only see the 2 monitors on the GTX960. :confused:

Ok so I have figured out a bit more but still not getting any luck, at the moment I am just trying to get 1 of the monitors on the other card working and I have arrived at the following nvidia.conf

# nvidia-xconfig: X configuration file generated by nvidia-xconfig

But System Settings still does not see the Monitor and nVidia Control Panel is the same in that it it just says "New X Screen Requires Restart" but won't enable the Apply button or do anything?!

So, did you reboot your system after modifying the /etc/X11/mhwd.d/nvidia.conf or you are still looking for a on-the-fly apply button and changes to take effect without reboot?
If you did reboot, have you tried nomodeset and without conf file ?

I did reboot yes, I have found that if I set both GPU's to MutliGPU = On then I at least get the options to set the 2nd GPU's screen resolutions etc. but if I apply this it wipes out the first GPU's monitors, it seems I can get either GPU working but not both.

Don't no about "nomodeset" so haven't tried that how do I do that please?

Thanks

So, you did not read this yet
https://wiki.archlinux.org/index.php/multihead

You add it as kernel boot parameter at GRUB boot menu. Press e to edit, replace quiet with nomodeset and then press F10 to save and continue booting.
Check again your nvidia.conf as i'm sure you will spot the mistake once you read the wiki ...

Hi,

Yes I did read that but it hasn't worked for me so far, I tried with nomodeset and that left the other two monitors live showing last console text but nothing more and they couldn't configure them still.

I can get them fully configured in nvidia-settings now all showing all with correct resolutions detected and assigned to all devices, save the config file and boot from that and all it does it break my ability to even try to configure the secondary gpu's monitor's.

I can never actually get the monitors on the second GPU which ever one that is at the time to come live!

I can restore this function by changing "MultiGPU" to true but that just takes me back to where I started in that I can only configure them for appearances.

nVidia settings won't apply it as needs to new X Screen seem to be where it stop, I save config reboot still needs new X Screen, can I force the creation of a new X Screen another way would that help?!

At least I can use this now on my main monitors! :smiley:

This is my current config as generated by nVidia settings, it included the monitors, gpus and screens.

If this is wrong I fail to see it myself and it's as generated by the nvidia app itself...

Thanks

use
Option "Xinerama" "1"
Also you forgot this last lines from the original config:

Not sure this are correct values or if by using them that particular monitor is not actually working.

For each Device you have to add the Screen. Example for Device 0:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    Screen          0
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce RTX 2080 Ti"
    BusID          "PCI:2:0:0"
EndSection

maybe you have to add under the BusID this lines too:

    Option          "RenderAccel"   "true"
    Option          "UseEdidFreqs"  "true"

Hey thanks,

I tried with and without Xinerama and got no luck, but all this does as far as I am aware if merge the monitors into one anyway which is not what I want to do, certainly not for all of them anyway.

I did notice those lines were now missing but I have tried with those in and out and it doesn't seem to make any difference, not a noticeable one anyway.

That monitor with the 0's is right, if I enable the 960 over the 2080 it set up both monitors on that card using the details above and it works, that's where I pulled it from.

The only monitors which don't get listed there is the 2nd ASUS PB287Q and the Samsung 4k, but oddly both of these are working when the 2080 is enabled though they are not listed.

I tried creating a file last night which contained all 5 monitors and a separate section for each screen and it just broke simple display manager I had to revert it.

Gona have to reinstall anyway tonight now! :frowning:

I noticed the partition I created was already nearly full so I tried to move it lol, this failed now it's not recognised, oh well only a few days in, will copy the games elsewhere format it with Linux at the start and with a much bigger partition before moving the games back and installaling, I expect I'll be back were I was by the end of the night. :frowning:

I haven't tried the RenderAccel or UseEdidFreqs I will try those later though all work with respective configs on their own so I don't think that is the problem myself, but we'll see.

Thanks

Ok back up and running with config file with the extra parameters but still the same problem, Manjaro settings windows does not show additional GPU's Monitors but nVidia settings does, just you can't create an X Screen to get them up and running.

EDIT: Just so we are clear this is a completely fresh install now, the only thing changed is the nVidia config file which gets me on my main 3 monitors but not the additionals.

Gona paste some outputs here maybe useful...
