Default Claims to be right resolution, but isnt

Ive been posting all over town but cant elicit a response. Hopefully you guys will be able to help.

Im running Kubuntu (Dapper Drake) on an AMD64 with Quadro FX Go1400.

I cannot get my resolution right using the nvidia driver (nv works alright). I have had it briefly on several occasions but it disappears after a reboot or something.

I have built the nvidia-kernel module from source as I couldnt get anywhere with the binaries. Im sure my xorg.conf is, or at least has at some point been, fine (relevant sections below). When I log in the resolution is reported to be 1920x1200 (what Im trying to get) but clearly its not.

Ive been trying everything I can find on the web. My most recent success came from running "dpkg-reconfigure xserver-xorg" and rebooting. It booted with 1680x1050 but I was able to increase it in the display applet and got the full 1920x1200, but on reboot it was gone and I havent been able to reproduce this effect.

The relevant section of my xorg.conf as it currently stands is:
Code:
Section "Device"
        Identifier      "NVIDIA Corporation NV41 [Quadro FX Go1400]"
        Driver          "nvidia"
        BusID           "PCI:2:0:0"
        Option          "UseFBDev"              "true"
#       Option          "UseEDID"               "FALSE"
EndSection

Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       30-75
        VertRefresh     30-60
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "NVIDIA Corporation NV41 [Quadro FX Go1400]"
        Monitor         "Generic Monitor"
        DefaultDepth    24
        SubSection "Display"
                Depth           1
                Modes           "1920x1200"
        EndSubSection
        SubSection "Display"
                Depth           4
                Modes           "1920x1200"
        EndSubSection
        SubSection "Display"
                Depth           8
                Modes           "1920x1200"
        EndSubSection
        SubSection "Display"
                Depth           15
                Modes           "1920x1200"
        EndSubSection
        SubSection "Display"
                Depth           16
                Modes           "1920x1200"
        EndSubSection
        SubSection "Display"
                Depth           24
                Modes           "1920x1200"
        EndSubSection
EndSection

I'm not clear on how you determined that you were not getting 1920x1200. All of the information you've provided indicates that you are running X at 1920x1200.

Oh my, Im so embarrassed.

The resolution is 1920x1200. It appears to be that the fonts are just oversized, or something, making all my windows look like something I used to work on back in the 90s.

xdpyinfo tells me that with nv I am getting 75dpi, and with nvidia I am getting 152dpi. By my logic this should make my fonts (9pt) appear half sized on nvidia when compared to nv, not vice versa as is happening. Ive attached a screenshot taken under each driver to illustrate.

This is covered in the README (and has also been discussed in other threads on this forum before):

I should be but Im still too ashamed of myself...

I dont know if this is a solution or a workaround but itll do for the moment.

In /etc/kde3/kdm/kdmrc:

ServerArgsLocal=-nolisten tcp

goes to

ServerArgsLocal=-dpi 75 -nolisten tcp

or some other suitable value.
