Subject: Re: Problem running demos when using Framebuffer option

About mouse, I did this on my RH 7 box:

# /etc/init.d/gpm stop
# gpm -R -t imps2

NOTE: use your mouse type, I used it for my PS/2 wheel mouse.

About graphics make sure you used config.fb as config before make, if all 
else fails try 789 instead of 0301.
