Linux on a TI Extensa 560 CD [link http://home1.gte.net/bolan/laptop/laptop.html ist tot]
The 570 CDT has a Cirrus Logic CLGD7543 Chipset and 1 MB video ram. The only way
to get 800x600 going is to use a patched XF86_SVGA 3.1.2 server.
Otherwise you get 640x480 with ugly fonts. Without the patch the screen blanks (some people say forever with exploding batteries :-/, I don't believe that though, but be careful with Xfree86 !!!).
Thanx to Eric Andersons XF86_SVGA patch the 800x600 resolution works really great using the following XF86Config File.
Even though the CD has a passive matrix screen, you have to set the environment variables to force it to go into active matrix mode. Then, you cycle the video between internal and external (the screen has gone black at this point). And when things magically reappear, you have X on your 570 CD. The environment variable is: ASCENTIA950N-ACTIVE The code just checks to see if it is null, so it just needs to be some random value. Warning -- startx resets your environment, so setting the environment variable and then invoking startx doesn't seem to get it propogate. Other notes - if people want the patches for the 3.1.2 distribution to recompile themselves, I made Eric Andersen's patches to cir_driver.c and cir_driver.h compile (no real magic, just some simple stuff that got changed. I haven't sent them to him yet).
