The default depth configuration may depend on which version of Xfree86 you are running. Check /var/log/XFree86.0.log
I'm running version 4 (woody) and in /etc/X11/XF86Config I have Section "Screen" ... DefaultDepth 16 ... End Section I used XF86Setup to create the file in version 3 (potato) Hope this helps Ian. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
