Michael, Thanks. I used your configuration information extensively in getting my T30 up and happy. Of course, the XFree86 information was of limited use as IBM has switched from the S3 Savage to the ATI Radeon M7 chip. But it did give some ideas for different mode lines. Unfortunately, none of these seems to make a difference. :-( Since Windows seems to have no problems and simply having the screen blank (but not shut off) causes no problem, I suspect that it is a timing issue of some sort in the turn-on operation. The Windows drivers probably do something a bit differently that makes it work. I imagine FreeBSD and XFree86 simply rely on APM to "do the right thing" and that does not work in this case. Probably something that BIOS could fix, but IBM is barely willing to admit that FreeBSD runs on these boxes, so I doubt that they will be very receptive. Now, if Linux does the same thing, I might get somewhere as IBM spends a lot of effort there. I have not seen any reports of this on XFree86 xperts list, so I suspect it does not happen there. :=( Ah, well. I guess I'll put out a plea to 1400x1050 ThinkPad users on xperts and see if I can get confirmation one way or the other. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
