[Openchrome-users] Openchrome on Samsung Q1B

[Massimo Vighetti]

Hi all

I'm using Ubuntu on Samsung Q1B, ultra mobile PC with 7" touchscreen
LCD.

I compiled last trunk in Ubuntu 8.04 and it solved many of my problems.
Touchescreen driver is evtouch.

Now CX700 works fine in 800x600 and 800x480

I have just 3 little fix to do

1) in 800x600 characters a shown cutted (lines of horizontal pixels are
missing)

2) in 800x480 I've have perfect characters and bitmap but virtual screen
size is still 800x600 and my lower section of screen isn't visible.
I tried to set DisplaySize and Virtual in xorg.conf, but with this
options X no longer use openchrome driver and load vesa.

3) I'm not able to set X to start in 800x480.

Reading Xorg.0.log I see following lines

=============================================================
(WW) CHROME(0): Unable to estimate virtual size
(II) AIGLX: Loaded and initialized /usr/lib/dri/unichrome_dri.so
=============================================================

and row of modeline 800x480 activation hasn't frequences parameter

(==) CHROME(0): DPI set to (96, 96)
===============================================================

I don't know if it is right.

Attached Xorg.0.log and xorg.conf.

Can you help me?

Thanks
