Kevin, A little while back I wrote up some docs on getting every darn thing I could think of at the time working on my once shiny new T23 here. Not so new anymore, but still kinda shiny :) I've personally never had the problems that you're describing. Running XFree86-4.2.0_1,1 4.6-STABLE FreeBSD 4.6-STABLE #2: Mon Aug 5 18:56:35 PDT 2002 The archived copies of these posts... Part 1 http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=135463+147430+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile Part 2 http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=147430+154009+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile Part 3 http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=154009+159374+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile I've only done a little tweaking on these since then. A couple of things worth noting though... Get into your bios setup and change the parallel port address to 378 or FreeBSD just won't see the darn thing. You'll get a lot of "Stray IRQ 7" errors. The kernel code changes appear to be mostly in place as of the latest STABLE. They were not in place as of 4.6-RELEASE. I've replaced those changes with the latest STABLE... it works, but not as well as the patches that I referenced. More info on that in a follow up mail to this list. Be sure to get all the latest bios updates from IBM's web site. You'll probably need a DOS boot disk in order to run them though :( I would not recommend trying to get 1280x1024 going. Kind of a general rule for LCD displays, but things look like crap if you're not running at exactly the same resolution as the monitor. Give a look in /var/log/XFree86.0.log to see if there's anything noteworthy in there that might clue you in as to what is going on. I'd be curious to know how that works out for ya.
