Hardy X autoconfig doesn't like my hardware - can I use a xorg.conf from a previous version?

Asked by Caroline Ford

This is request for help with dealing with the effects of Bug #185440.

The new xorg autoconfiguratiion stuff does *not* like my hardware. Xorg.conf is full of items called "Configured Foo" without explaining how and where they are configured..

As it hasn't configured itself properly and reconfiguring just produces the same can I use a xorg.conf from an earlier version of X? Can you still edit these new almost content-free xorg.confs?

With old(er) hardware there are loads of workrounds that involve changing options in xorg.conf.

I know that the bug has been filed against the Trident driver, but I can't see how it's going to get fixed.. I just want a usable machine!

Could you please post your current xorg.conf and the one you're wanting to replace it with?

This is the current xorg.conf. sudo dpkg-reconfigure -phigh xserver-xorg produces an identical file.

xorg.conf (X.Org 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 xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I'm not sure what to add. I've found the following in google:

Its totally safe to alter the xorg.conf to your liking, and to change it to an older state. What the new autoconfiguration does is filling in the gaps if no options are set in the xorg.conf, thats why it is relatively empty. As soon as there are options and values defined in the conf file, X uses these.

Thanks Hendrick Musche, that solved my question.

In some cases X reverts to low resolution and creates a new conf file, instead of using entries manually added to the default file created by dpkg-reconfigure -phigh xserver-xorg. Not even VESA (let alone NVIDIA) works.
