Ok, I built tdfxfb as a module and compiled MPlayer using --with-tdfxfb.  To be on the safe side, I did "modprobe tdfxfb" (which, incidentally, did some weird stuff to my screen while in console--see bottom).  MPlayer is still not working, though--when I try to open a movie by running "mplayer -vo tdfxfb filename", it says "tdfxfb: can't open /dev/fb0: Permission denied."  This despite the fact that my login is in the group that /dev/fb0 is in.

I tried opening a movie in the same way while logged in as root, but again it fails, saying "tdfxfb: can't open /dev/fb0: No such device" which is incorrect:

geoff:~$ ls -l /dev/fb0
crw--w--w-    1 root     tty       29,   0 Dec 27 21:05 /dev/fb0

Any thoughts or ideas?


As for the "weird stuff" when I load tdfxfb, when I do it in the console, the screen goes black for a second, and then comes back, but the cursor is HUGE.  Maybe an inch and a half tall, and proportionally wide.  The font is a little squished, vertically, as well.  Everything else still works alright.  When I try loading the module in X-Window, the screen goes black permanantly.

Thanks for your help.
