LinuxQuestions.org - Changing Resolution

Same as in every other distro - edit your xorg.conf file. Find the bit that shows resolution and change it.

Mine is:
Code:
# **********************************************************************

# Screen sections

# **********************************************************************



# Any number of screen sections may be present.  Each describes

# the configuration of a single screen.  A single specific screen section

# may be specified from the X server command line with the "-screen"

# option.

Section "Screen"

    Identifier  "Screen 1"

    Device      "VESA Framebuffer"

    Monitor    "My Monitor"



# If your card can handle it, a higher default color depth (like 24 or 32)

# is highly recommended.



#  DefaultDepth 8

#  DefaultDepth 16

  DefaultDepth 24

#  DefaultDepth 32



# "1024x768" is also a conservative usable default resolution.  If you

# have a better monitor, feel free to try resolutions such as

# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your

# card/monitor can produce)
