I had some help on Ubuntu board.

I first did that:

sudo apt-get install xserver-xorg-video-i810

and answer was I had the latest version

Then I changed xorg.conf to force it to use i810 like you wrote:

Section "Device"
        Driver      "i810"
    Identifier    "Configured Video Device"
EndSection

After reboot, it works.

So, it was a device problem, Xfce did not recognize my graphic card and was not able to use the proper driver/settings.

I did NOT have this issue with LiveCD of Ubuntu, with Gnome.

During and after install of Xubuntu using Wibi windows installer, I get font size really HUGE (like this) everywhere (login/desktop/...) makig the GUI completely not usable.

in fact the all windows of the GUI are HUGE, seems it is more related to a screen size trouble.

It is insatlled on my gf's laptop: a Toshiba Satellite pro (pentium M).
I don't know the reason why and what to do to fix this.

Of course, I've searched the ubuntu and Xfce board first before posting but I didn't find any suitable answer to help.

I'm closer to a linux newby than a guru, but I've managed (it took me some time) to read under root (console mode, not GUI) the content of xorg.conf

the screen part is like this:
Section "Screen"
Identifier "Default Screen"
Device "xxxxxxxx"
Monitor "Generic Monitor"
EndSection

but I believe it should be like that :
Section "Screen"
Identifier "Default Screen"
Device "xxxxxx"
Monitor "Generic Monitor"
Defaultdepth 24
SubSection "Display"
Modes "1280x800"
EndSubSection
EndSection

xxxxxx means I can't remember what was written

Anyway, if I was able to read under root with command:

vi /etc/X11/xog.conf

I was not able to add lines and modify the conf file. Maybe it is not the solution, but I'd like to find out.

I've tried to use the GUI in order to go to pref and try to fix this, but no way. Impossible because all desktop is HUGE. In fact Font size is adapted to the window size, means my monitor screen is like 25% of the complete desktop size.

I'm still looking for some advices to fix this.

Thanks for your help,
