1. Linux graphics
It appears that there are some peculiarity with respect to Linux
doing graphics (and not just X, although it's affected, too) on a
Toshiba laptop. Anyone got some pointers for me to do some
research on this problem, so I can finish up the revised
biplatformal graphics.e and test it?

2. Re: Linux graphics
You'll notice that the biggest problem with Linux and laptops is
getting the video to work out. Have fun. Actually, try monkey linux or
similar umsdos-based distro where you boot dos first and see if the
problem still exists. If not, there's nothing you can really do about it
(except perhaps continue using that distribution). If so, then it looks
like an implementation thing, which means it can be fixed easily.
This is just my expoerience.

For a comprehensive list of laptops and Linux compatibility, start here:
Then here are a few more specific sites:

Yes, I'd gotten about that far. It looks like it _almost_ wants
to work, but at a really wild-assed guess, I'd say that it's
trying to interlace a non-interlaced display or vice-versa, and
at the wrong resolution to boot.

Had it on DragonLinux and on LoopLinux. Loop isn't a
UMSDOS-based linux, but it's also not a must-boot-on-
bare-hardware distro either - it's a reboot-to-MSDOS-mode distro.
Dragon is a UMSDOS distro. No difference in the symptoms of the
problems - which leads me to believe that there's a
driver-related problem somewhere, and you can't treat a laptop
based simply on chipset. That's why I wanted pointers so I could
look for more information - I'm not afraid to get my hands dirty,
but I want to start out with at least an idea of what I'm getting
covered with grease _from_.

6. Re: Linux graphics
Maybe this will help, or maybe not...
But more info is usually better...
here is an article on a new gui for Linux called Eazel
http://www.maximumpc.com/content/2000/02/19/10819
Don't think its out yet. My understanding is that there is a whole new
xwindows version, that is supposed to be much more friendly and high
performance.

Well, that's the best attitude. You learn lots that way. If you
solve the problem I would be very interested to hear your solution, since
I'm itching to buy a lappy soon -- and I haven't seen a laptop ever run
linux properly for reasons related to the display.
Good luck.

One which works just fine with Linux is the WinBook XL (imagine that!).

Two others are the ancient Samsung sens 800 and the very nice Sony VAIO
Z505RX.
But, back to the subject of Linux graphics...
My Neil2 graphics library works in Linux as well as DOS and Win32 (well
win32 is still really bad)
If run on Linux, it will try to use X in a window if it can connect to the
display, otherwise it will use SVGAlib. You can rip anything you want from
the Neil2 source code that suits you. Most of the time it just sets up a
linear buffer in memory that it can peek/poke directly.
For the Xlib programming, I found a great source at
http://www.emi.u-bordeaux.fr/~turpeau/xlib.html

Hey, Pete!
This works great on Linux, in xWindows. Thanks for the great work!
