[VX820, VIA] no X11 with vesa on Samsung NC20

[aanno]

I'm using a Samsung NC20 since a couple of years now. It has never been easy with X11 but with Ubuntu 13.10/saucy it has become an expert issue to get this netbook running.

Notice that this is a regression from Ubuntu 13.04/raring where openchrome was working more or less flawless. As openchrome fails [https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-openchrome/+bug/1251849], I forced the vesa driver with the following in /usr/share/X11/xorg.conf.d/42-vesa.conf

Section "Device"
 Identifier "Configured Video Device"
 Driver "vesa"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
 Option "PanelSize" "1280x800"
 Option "PreferredMode" "1280x800"
 Option "DefaultModes" "true"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
 DefaultDepth 24
 SubSection "Display"
  Virtual 1280 800
  Depth 24
 EndSubSection
EndSection

However, even with the vesa driver, X11 bails out and even the console is not usable afterwards.

I use the vesa drivers adding xforcevesa .. Set a wrong resolution "1280 * 768" like, detects openchrome "1280 * 800" to my screen the correct resolution is "1024 * 768" ..

I correct the correct resolution for my screen I think is 1280 * 800
