Absolutely. Remember IRIX's winterm? That's the speed you get. I ran KDE 3.5 on mine which wasn't anywhere near as sluggish as you'd expect form a 200MHz R5k ( ok, building it took forever but once that was over things weren't too bad ) The driver accelerates both basic colour expansion ( for xterms ) and some xrender ops, the latter helps KDE's perceived speed a lot ( actually, the reason to muck with KDE was to have a bunch of handy test cases for xrender ). > I tried installing Debian on one of those machines once but the time > it takes to boot is way too long. Maybe it has something to do with > slow CPU and compressed initrd. NetBSD boots to multiuser in about 20 seconds or so on a 200MHz R5k O2 with no 'fast init' trickery whatsoever. I have no idea what's up with recent linux to slow down the boot process. have fun Michael _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
