Hi Folks,

im experiencing problems with a Qtopia program.

When I try to open it i get the following error message:

Can't open framebuffer device /dev/fb0
Can't open framebuffer device /dev/fb0
Can't open framebuffer device /dev/fb0
Segmentation fault


As a beginner to Linux I cannot figure out how to fix that...

Any suggestions would be appreciated!

The device nodes used to access the framebuffer module aren't present in /dev.  This means they need to be made with mknod.

mknod /dev/fb0 c 29 0
mknod /dev/fb1 c 29 1

etc.

I had to do the same thing with my system.  The 29 is the major number for the framebuffer device and the 0,1,etc is the minor number.  The 'c' stands for character since this is a character device.

If you're running a non persistent system you'll probably have to remaster the disk to add these nodes.  If you need more help, post your boot process, i.e. cd boot, hd-install frugal, etc.
