    And have you held broken packages? Your repositories that you've been sitting on since 2016 could be in any state, and we've got no way of knowing because you haven't told us. Or even basic stuff like whether you remembered to run an apt update after you added the PPA to refresh the list of available packages.

    What you mentioned about /etc/X11/xorg.conf.d is not here. So I don't know where to start from.
    No, it's not there by default these days. It will be used if you create one. xorg.conf.d is a directory that can hold snippets so that you don't need to do a full xorg.conf. There's a bunch of information available about it. You only need to give it the information that it would otherwise be getting from the monitor through EDID.

    Re: Low resolution after upgrade

    I always run apt update when I add a PPA or prior to an upgrade. Synaptic says that I don't have any broken packages - only when I attempt to install 304 is when I get these messages. Is it possible that these dependencies cannot be installed in 18.04 but where available in 16.04? Can you give me a pointer to how to generate this folder /xorg.conf.d so the system will get the right resolution?

    It's unlikely that it can't be installed at all in 18.04; the graphics-drivers team is small but generally competent. It is very likely that it's your package manager's particular history and configuration from 16.04 that's stopping you from installing it.

    Can you give me a pointer to how to generate this folder /xorg.conf.d so the system will get the right resolution?
    The folder is just a folder. You'd make it with mkdir and create a file in it. In that file you'd include the correct values for your monitor. You can read more about the file here, for example.

    Re: Low resolution after upgrade

    This is my /etc/X11/xorg.conf.d/20-monitor.conf:
    Code:
    Section "Monitor"
            Identifier      "Configured Monitor"
            HorizSync       30-80
            VertRefresh     49-75
    EndSection
    
    
    Section "Screen"
            Identifier    "Default Screen"
            Monitor        "Configured Monitor"
            Device        "Configured Video Device"
            DefaultDepth    24
            SubSection "Display"
                    Depth    24
                    Modes     "1920x1200" "1280x1024"
            EndSubSection
    EndSection
    but I can't still get the 1920x1200 resolution, is there anything wrong or incomplete in this file?

    Yes.

    You've just copied the values for someone else's completely different monitor rather than looking up your own.

You can generally find those values in the specifications or manual of your monitor.

    Re: Low resolution after upgrade

    It turns out that I found an old xorg.conf file (xorg.conf.03312015) that was set up by nvidia settings in 2014 (probably Ubuntu 14.04) and is:
    Code:
    # nvidia-settings: X configuration file generated by nvidia-settings
    # nvidia-settings:  version 331.20  (buildd@komainu)  Mon Feb  3 15:11:14 UTC 2014

        InputDevice    "Mouse0" "CorePointer"
        Option         "Xinerama" "0"
    EndSection
    
    
    Section "Files"
    EndSection
    
    
    Section "InputDevice"
    
    
        # generated from default
        Identifier     "Mouse0"
        Driver         "mouse"
        Option         "Protocol" "auto"
        Option         "Device" "/dev/psaux"
        Option         "Emulate3Buttons" "no"

    EndSection
    
    
    Section "Monitor"
    
    
        # HorizSync source: edid, VertRefresh source: edid
        Identifier     "Monitor0"
        VendorName     "Unknown"
        ModelName      "Seiko/Epson"
        HorizSync       30.0 - 75.0
        VertRefresh     60.0
        Option         "DPMS"
    EndSection
    
    
    Section "Device"
        Identifier     "Device0"
        Driver         "nvidia"
        VendorName     "NVIDIA Corporation"
        BoardName      "Quadro FX Go1400"
    EndSection
    
    
    Section "Screen"
    
    
    # Removed Option "metamodes" "nvidia-auto-select @3840x1200 +0+0"
        Identifier     "Screen0"
        Device         "Device0"
        Monitor        "Monitor0"
        DefaultDepth    24
        Option         "nvidiaXineramaInfoOrder" "DFP-0"
        Option         "Stereo" "0"
        Option         "metamodes" "nvidia-auto-select +0+0"
        Option         "SLI" "Off"
        Option         "MultiGPU" "Off"
        Option         "BaseMosaic" "off"
        SubSection     "Display"
            Depth       24
        EndSubSection
    EndSection
    so I copied what I thought would be the relevant lines into /etc/X11/xorg.conf.d/20-monitor.conf
    Code:
    Section "Monitor"
            Identifier      "Monitor0"
            VendorName      "Unknown"
            ModelName       "Seiko/Epson"
            HorizSync       30.0 - 75.0
            VertRefresh     60
            Option          "DPMS"
    EndSection
    
    
    Section "Screen"
            Identifier      "Screen0"
            Device          "Device0"
            Monitor         "Monitor0"
            DefaultDepth    24
            SubSection "Display"
                    Depth    24
                    Modes     "1920x1200" "1280x1024"
            EndSubSection
    EndSection
    but I still didn't get it to use the whole resolution.

    Re: Low resolution after upgrade

    I added the following two lines to /etc/default/grub:
    Code:
    GRUB_GFXMODE=1920x1200x24
    GRUB_GFXPAYLOAD_LINUX=1920x1200
    but it didn't solve the issue

    I posted the issue on https://www.linuxquestions.org/quest...er-4175665365/ and they solved it. In any case, thanks for your time.
