x on ml300?

Hi,

I'm trying to write a graphics demo program on an ML-300 board with 
embedded PowerPC CPU and 128MB of RAM, no graphics acceleration chip. I 
got the linux kernel running, and have been advised that regular X11 
will not run because it takes too much memory and I need to run some 
other memory-extensive tasks on the background.

Does anyone know of a good widget toolkit that can solve my problem? 
Thanks in advance.

The Linux demo shipping with the ML300 runs X11 just fine.

Crazy talk. X11 runs fine in 128Mb of RAM on PowerPC. I'm building a
demo embedded application around a PPC-Linux box (603e) with 64Mb of
RAM (external video RAM), running X11.

Do you have a swap partition on something as well?

and swap is very limited.

Yes, but you didn't quantify that at all. If you're saying that what
you meant to post was "Can I run X on a machine with 128Mb RAM and no
swap, given that my application absolutely requires 127.5Mb of RAM to
itself", then that's a different question.

Simple test:

free ; X & ; sleep 30 ; free ; killall X

(or something like that).

If so, it'll be the *other* things that're killing you, not X11.  X11
can feel like a memory hog if you have 16 MB or less.  I've been using
a 16 MB (later upgraded to a wopping 32 MB) Pentium-100 Linux box as
my key X11 terminal for years.  It ain't overwhelminly fast, but it
works.

Switching away from X11 to something else is not going to gain you
enough memory to pay for the hassle.
