While that's true, VESA isn't as bad as martin is describing his situation. I use vesafb on a Duron 750MHz, 256MB RAM, and a SiS6326 (yes, very cheap) video card. For normal usage it is just fine. I can type stuff in vim and view pages in galeon without trouble. I even run xosview, xmms, esd, and other background apps continuously (not to mention exim, apache and jabber, and sometimes zope and postresql). Certainly if I try scolling line-by-line through a long document the system will drag. (instead use <PgUp>/<PgDown> in galeon for a _big_ reduction in lag time) I can also peg the CPU if an app or script spews lots and lots of output (either to gnome-terminal to to the console). Also, tuxracer is unusable and I need to pause realplayer periodically or else the audio lags noticeably behind the video. However, those are "extreme" conditions, wrt video. For basic stuff like typing an email in vim, vesafb is plenty fast enough. Oh, yeah, I'm using XFree86 4.1 also. -D -- "Open Source Software - Sometimes you get more than you paid for..." http://dman.ddts.net/~dman/
