I have Red Hat 8.0 runninng on a Toshiba Satellite 5100 laptop. Now I want to use a FLATRON LCD 568LM moniter via a USB cable. When I boot up, the linux boot text appears on the new moniter, but when it is time for the blue screen, the moniter goes black except for an error window which says
"out of frequency" ...tthen powersave....then times out in seconds
(i'm pretty sure this window is generated by the moniter itself).
I have tried changing
etc/X11/XF86Config
so that the horizontal and vertical scan ratess are what is specified in the specs for this monitor, but the problem
persists.
Is there another obvious thing to try?
How do you diagnose a problem like this?
I am just learning my way arround Linux, so any detailed info would be appreciated.
I've never run RedHat, so this may be a bit of a blind question, but do you also have a /etc/X11/XF86Config-4 file as well as the /etc/X11/XF86Config you say you've edited? If you do, it -4 file will have priority.
DPMS is, if I remember correctly, to do with power management of the monitor. I'm not quite sure why it's saying out of range if the values you typed in are correct, though you may as well post the XF86Config file here so someone else could take a better guess.
Section "Files"
# The location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
RgbPath "/usr/X11R6/lib/X11/rgb"

# Option "Protocol" "Xqueue"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"

# If you'd like to switch the positions of your capslock and
