Hi, Here's something to check:
The postinst script only regenerates /etc/X11/XF86Config-4 if it is unaltered since the previous dpkg upgrade. This is achieved by keeping the md5 checksum of /etc/X11/XF86Config-4 in /var/lib/xfree86/XF86Config-4.md5sum. Is it possible that either (1) /etc/X11/XF86Config-4 has been customised manually since the last upgrade; or (2) /var/lib/xfree86/XF86Config-4.md5sum has been removed? If either is true, you can force the dpkg upgrade to regenerate XF86Config-4 by doing: "md5sum /etc/X11/XF86Config-4 > /var/lib/xfree86/XF86Config-4.md5sum" and then doing dpkg-reconfigure again. This will write the latest md5 signature into the checksum file and trick dpkg-reconfigure into proceeding with overwriting XF86Config-4. Regards, Frank Chung
