This is the first time I have experienced it.

I always test pre-release isos when asked on lubuntu-devel on this
particular netbook (Samsung NC10, 'hawking')  so it is probably safe to say
this is a new problem.

The graphics PCI devices are:-
VGA compatible controller : Intel Corporation Mobile 945GSE Express
Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])
Display controller : Intel Corporation Mobile 945GM/GMS/GME, 943/940GML
Express Integrated Graphics Controller (rev 03)

Here is what I believe might be going on:-

There is a graphics issue. I think the kernel parameters "splash quiet"
somehow result in the graphics subsystem is somehow put into the wrong
mode, resulting in the wrong piece of memory being used for part of the
display, resulting in 80% of the screen being junk and 20% of the screen
being perfect.

It appears that booting from being switched off completely, with the kernel
parameters "quiet splash" removed, prevents the problem from happening in
the first place.


BW,


Ian
