Hi,

I'm trying to enable framebuffer on this Ubuntu machine but I'm having problems. Whatever I try in GRUB menu.lst file, like "vga=0x31A", "vga=795" and other modes, I get the message "(...) undefined mode number (...)".

I have two machines running without any problem and I don't know why this machine is showing this message.

Is it a module I didn't install? If no, what is the problem?

Thank you.
