XFree86 resolution problem

[MacMiskenn]

Hi!
I just installed Debian on an old pc.
Afterwards I installed XFree86 and Gnome, I can start X, but for some reason I can't change my resolution to 1024x768.

I'm fairly sure that the HorizSync and VertRefresh are set correctly.

This is my XF86Config-4:

# XF86Config-4 (XFree86 X Window System server configuration file)
#
# This file was 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.)
#
# This file is automatically updated on xserver-xfree86 package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xfree86
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following commands as root:
#
#   cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.custom
#   md5sum /etc/X11/XF86Config-4 >/var/lib/xfree86/XF86Config-4.md5sum
#   dpkg-reconfigure xserver-xfree86

And this is my XFree86.0.log.

I'm new to linux, so it would'nt surprise me if I made some odd mistake when I configured X.

Also I tried using the Ubunto Live CD, and everything works fine from that.

I followed this guide, when I installed X, I know it's in danish, but you can see the commands I used in it.

I suggest you try DefaultDepth 16 instead of the default 24.

[MacMiskenn]

Thanks, that worked
Can't believe it was that simple

[antidrugue]

Glad it worked.

Some cards don't support higher resolutions when using 24 bits colors. Anyway 16 bits depth makes no noticeable aesthetic difference, and it's much faster.
