Hi all,
I have exactly this problem with debian lenny. I have no X server, and the vga=791 option in menu.lst doesn't work for me.
When I boot with that option, Grub says to me that the maximum resolution supported is 80x90 or something similar.
So does anyone know how to change shell resolution to 1280x1024?
Thank you,
Daniele
Update: I ran the command hwinfo --framebuffer in order to see the resolution my screen supports and, between others, I can see the following:
Mode 0x0317: 1024x768 (+2048), 16 bits
Mode 0x0318: 1024x768 (+4096), 24 bits
Mode 0x031a: 1280x1024 (+2560), 16 bits
Mode 0x031b: 1280x1024 (+5120), 24 bits
Every time I put one of this hexadecimal values in the "vga= " option in menu.lst, after the reboot, I receive the "Undefined Video Mode Number error message", basically saying me that I'm limited to the text modes resolutions (maximum is 80x60).
I don't understand where the problem is...
Update: Problem Fixed
The reason was that the nvidia framebuffer support is not enabled by default on debian lenny. So the solution was a kernel recompilation enabling that feature (Device Driver > Graphic Card > Framebuffer Support > Nvdia Framebuffer)
After this, my console is 1280x1024:

There was no need to edit menu.lst with vga=79x options! the best resolution was set automatically :-)
