I used the tool dpkg-reconfigure xserver-xfree86 to set up my video settings. I told it to only use 800x600 as the resolution. It will only come up as 640x480. How do I fix this? Here is the config file:

### BEGIN DEBCONF SECTION
# XF86Config-4 (XFree86 server configuration file) generated by dexconf, the
# Debian X Configuration tool, using values from the debconf database.
#
# Edit this file with caution, and see the XF86Config-4 manual page.
# (Type "man XF86Config-4" at the shell prompt.)
#
# If you want your changes to this file preserved by dexconf, only make changes
# before the "### BEGIN DEBCONF SECTION" line above, and/or after the
# "### END DEBCONF SECTION" line below.

# To change things within the debconf section, run the command:
# dpkg-reconfigure xserver-xfree86
# as root. Also see "How do I add custom sections to a dexconf-generated
# XF86Config or XF86Config-4 file?" in /usr/share/doc/xfree86-common/FAQ.gz.

No... That doesn't work. Anyone else?

in redhat there is Xconfigurator or something like that
in debian you have dpkg-reconfigure xserver-xfree86

slack prob has something like this -

This isn't about slack... my computer with slackware is fine

The problem is configuring using dpkg-reconfigure xserver-xfree86. I told it to allow higher resolutions and it doesn't. I know my monitor is capable of higher resolutions and I had my video settings at 800x600 with 16 bit color in windows.

after resetting it are you seeing "1024x768" anywhere in the config file? is it being written ok?

Yes. It is being written in the xf86config-4 file.

go to irc.debian.org #debian and ask.

sorry to busy to help at the moment.

check /var/log/XFree86.0.log and maybe ~/.xsession-errors

Try to see if the X server is reporting any conflicts.

/var/log/XFree86.0.log said my horizontal refresh rate was off. After some googling (no manual) I found my monitor (14" CTX CVP-5468NI) needed a horizontal refresh rate of 44.0-50.0 and a vertical refresh rate of 50.0-90.0. All supported resolutions now work correctly. Yeah!
