I really loved getting the widescreen framebuffer working - it was such
a buzz, so cool. That made for the ultimate in notebook usability and
portability.
I'm copying it here verbatim. It's made against a 2.6.11.n kernel and
may need a little polishing for newer versions, but it follows an easy
path, I've just extended the existing special format for toshiba's
libretto series:

Just use the libretto option (set to 1) and everything will work as
expected.
BTW, @Stroller: it's a 10 widescreen, 6 would be a
little too small...
That's really 10 not 6'??? How come I don't have a girlfriend??
;P
Well, size doesn't matter anyhow, does it ? ;-)

I believe they stopped support for the Picturebook's widescreen in the main kernel in 2.4 (around 2.4.20??) so it's good to see it working with a 2.6 kernel.

Google finds a photo at http://www.allnotebooks.ru/img/compl/51.gif I installed Gentoo on a Pentium II 400 Vaio Picturebook, the Sony with a 6 widescreen (1024 x 480??) but never had one of these CD-Roms available, only the floppy drive.

There are surely Linux distros that'll boot on this device so a pre-compiled kernel could be copied across from another machine and then only grub needs to be run, I think. Richard: does Knoppix boot from this CD-Rom drive? An Ubuntu LiveCD? Perhaps it might be worth trying an older (2003, 2004) Gentoo install CD. A Google for parallel port cd-rom linux returns, amongst others, this page http://cyberelk.net/tim/parport/paride.html so I reckon your drive is probably supported by the kernel. Stroller. Hey Stroller ... You got the model in 1 ...! I think you're correct. I'm going to try and use partition magic under Windows 2000 which is the OS it came with to create my partitions and install a stage 3. I'll let you know how I go. Hopefully having an EXT2 partition will help Knoppix start properly. Thanks, Richard -- gentoo-user@gentoo.org mailing list
