Hi, The behaviour the patch (035_tdfx_disable_dri_on_16mb_with_highres.diff) prevented sounds a lot like bug #179660.
I did some strace back then on an old version of xfree86. The thread mentioned in the bug report which contains them is moved. It is now in: http://bzbb.bzflag.org/viewtopic.php?t=105 Not sure if this helps, but it might solve / close 179660 as well. Cheers, Remco. P.S. I have a tdfx card (monster Fusion) and can do tests. Mail me if needed. -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
