changin virtual console resolution

recently i replace my monitor to a wide one.
the font looks huge in the virtual consoled - there is any way to change the resolution? (1680x1050)

thanks

Re: changin virtual console resolution

append vga=795 to the kernel command line (where you specify the root partition etc.), giving you a 1280x1024 fb (the largest possible with this method)

else you could try to use the fb module specific to your video adapter (radeonfb, savagefb...)

get the list with

modprobe -l |grep fb

maybe boot up without a vesa fb by appending:

video=vesa:off

before adding the fb module.

Re: changin virtual console resolution

fb stands for framebuffer, the area of memory (somewhere) that holds the stuff on your screen.

only using the specific module for your video card will get you your native resolution for your tty, but instead of video=vesa:off you could just put vga=795 to get a 1280x1024 framebuffer, which should show way more text, and look decent.

i use the module method, loading the radeonfb module in rc.conf:

in menu.lst (grub) i have:

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/mapper/vg0-root ro md=0,/dev/sda5,/dev/sdb2 5 quiet silent video=vesa:off
initrd /kernel26.img

and then i load the module in rc.conf:

#
# Modules to load at boot-up (in this order)
#   - prefix a module with a ! to blacklist it
#
MODULES=(radeonfb)

the module takes parameters, to set resolution and refresh, which you could specify somehow? in /etc/modprobe.conf, but that should be detected automatically (like xorg when you just specify a driver)

Hmm...I have black screen after load "aty128fb" module

 MODULES=(aty128fb pcspkr 3c59x mii slhc snd-maestro3 snd-pcm-oss i2c-dev i8k)

 # (0) Arch Linux

root   (hd0,0)
kernel /vmlinuz26 root=/dev/sda3 ro video=vesa:off
initrd /kernel26.img

Any idea?
