I recently came across an orphaned Samsung NC10 and started working on it (1.6Ghz Atom with 2GB RAM and a 60GB SSD). The display is (allegedly) a 1024x600 LCD with a 60 hertz refresh rate. It's driven by an Intel 945 Express. I installed Windows 10 and it runs at the appropriate resolution, and all the hardware reports in correctly against the manufacturer's spec above.

I then installed Lubuntu (so good) but cannot get it to display at the 1024x600 correct resolution. It looks pretty derpy on a wide-format screen.

I've tried using xrandr to add the correct resolution as a mode, as in this thread, but I got several unexpected gamma errors (although it sounds like they're not a problem?) and the computer doesn't do anything:

xrandr: Failed to get size of gamma for output default
xrandr: screen cannot be larger than 800x600 (desired size 1024x600)

Interestingly, if I go to Display Settings I can see the new mode, but selecting and applying it doesn't do anything.

Earlier I noticed that the screen has a min, current, and max of 800x600. So I lifted the xorg.conf file for the NC10 from here and then followed this process in order to add a virtual screen at 1024x600 @ 60hz to increase it, but when I reboot the machine it goes to a black screen (Ctrl+Alt+F1 console is available to revert). Here's what that looked like:

Section "Screen"
    ...
    SubSection "Display"
            Virtual 1024 600
    EndSubSection
EndSection

I'm pretty well at my wit's end. Any other ideas on how to get this laptop to detect the true screen resolution?

Had the same issue, solved by installing the correct video driver, so for my NC10 I did:

sudo apt-get update sudo apt-get install xserver-xorg-video-intel
