The "frame buffer" is normally enabled at boot time, so an appropriate boot command is required to activate it.

Unfortunately, 1024x600 is a strange resolution so you may need some special framebuffer command line to use it.

Search the internet with google for you laptop model number and "framebuffer", or learn the name of your graphics chipset and then search its name and the word "framebuffer".

There are no screen options for the Xfbdev server. It just takes your currently active "text window" framebuffer resolution and uses it to display XWindows.

Good Luck.

I figured out how the FrameBuffer works, and where in lilo.conf to specify what resolution to use at boot time (vga=XXX).
Unfortunately, I don't know what number to use. I've searched everywhere and have had no luck. How can I determine what vga number I should use to get a 1024x600 resolution?

I don't think there is a 1024x600 code.

You probably need some kind of special frame buffer driver besides the "vga=" one. Try doing some research on your video chipset and see if such a framebuffer driver exists. Hopefully it is included in knoppix/dsl by default.

Hi,

I also have a Toshiba laptop. In my bios (hold esc at boottime) there's an option "LCD Display Stretch". Maybe that can help with the black bar problem?
Stretch on and the boot using of the fb boots? (fb1280x1024 | fb1024x768 | fb800x600)?

Multichill, I've tried the "LCD Stretch" option in my BIOS both enabled and disabled and it had no effect whatsoever. What's odd though is that I once had Red Hat 9.0 installed on the machine with a resolution of 800x600, and it stretched the screen to fill up almost the entire display. I wonder why that doesn't work with DSL.
