intel atom 945g/ lilliput screen

[gomez2003]

Ok so heres my problem, i have the intel d945gcfl2d board running the atom 330 with the 945g chipset. I am using a lilliput 7" touchscreen (native resolution 800x480).

I'm using the latest stable build of the ubuntu netbook remix. My monitor shows up as "unknown monitor" in the display settings, it also doesn't detect any of the right resolutions.

Ive tried using some xconfig tutorials ive found:
https://wiki.ubuntu.com/X/Config/Resolution?action=fullsearch&context=180&value=start+yp+scripts&titlesearch=Titles

No luck :(

Ive tried installing 915resolution

No luck :(

Is there any way to either force the monitor to the right resolution or trick it to use something besides "unknown"?

fyi this is for a carPC

Thanks

ps i would really like not to have to use xp

You can try to set it manually by adding/editing the required lines (in red) to your /etc/X11/xorg.conf
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
SubSection "Display"
Modes "800x480@60"
EndSubSection
EndSection


You will have to know the native resolution and refresh rate of your laptop screen; don't blindly add these lines.

Thanks for the quick reply. I tried what you suggested and it did absolutely nothing.

I just want to clarify a couple things This is not a laptop, its a micro-itx motherboard with a VGA connection. The screen Im using comes up as "Unknown".

Here is a screenshot:

All of the refresh rate and hor/vertical values seem right on the 800x600, the picture is just squashed. So 800x480@60 should work if i can get it to show up.

Thanks again

no ideas huh? ive kept looking and have stumbled across virtual screens for running dual monitors. So i was thinking is it possible to run one monitor on a virtual screen? say 800x480 on a virtual screen of 800x600?

What we need to figure out is why 800x480 is not showing up. Maybe it is not listed as a supported mode in either the display or the graphics capabilities? Maybe it is showing a smaller range for hz/khz frequencies than it is actually capable of? During X startup, a whole range of modes are analysed, discarded, and then the best available is selected. Can you post your /var/log/Xorg.0.log file for a clue?

Considering your virtual screen idea: even if you set a virtual screen of 800x600, you will have the same problem of how to get the 800x480 resolution option.

You could try setting a virtual screen size of 800x480; that will discard 800x600 as a resolution option and (hopefully) force it into 800x480. (Though I suspect it will then pick up 640x480, and give you a scrollable 160-pixel horizontal edge).

You could also download 915resolution from the repositories; I've not tried this, but apparently it good for forcing resolutions on Intel graphics chipsets. At your own risk, please.

I actually got everything working!
both the 800x480 and the touch screen input.

Heres my xorg.conf:

# here are ignored.

# If you have edited this file but would like it to be automatically updated

# sudo dpkg-reconfigure -phigh xserver-xorg

And i added a startup script:
$xrandr --output VGA --mode "800x480"

its been working flawlessly
Thanks for the suggestions.
