The default X config file uses Vesa, basically the same driver that's dealing with framebuffering from boot, reagardless you need to configure X:
X -configure
Then follow the steps it gives you, Slack never configs X for you.
The framebuffering issue on bootup: go into /etc/lilo.conf and chang the setting that looks like:
Code:
# Override dangerous defaults that rewrite the partition table:
change-rules
reset
# VESA framebuffer console @ 1024x768x256
# vga = 773
# Normal VGA console
vga = normal
# VESA framebuffer console @ 1024x768x64k
# vga=791
# VESA framebuffer console @ 1024x768x32k
# vga=79
You can go to boring old vga=normal, which will almost no doubt work, but you may want to try one of the other possible modes, when you're finished just re-run LILO:
/sbin/lilo
