Re: x-setup and user defaults (was: /proc/cmdline limit of 256 chars)

I currently had a lot of trouble with mkxf86config (it didn't work with
my synaptics touchpad on my laptop) and came to a smaller (and hopefully
better maintainable) solution. It's in the attachment. Currently, one
should have fbset to use it, if /proc/cmdline gives no information. My
/etc/init.d/x-setup is in the attachment.

Another thing that is inspired by Paul is /etc/init.d/user that sets
user preferences. Currently, it requires gdm to work, but might easily
be adopted to kdm. I shortly looked at xdm, but found no auto-login
option for xdm, so probably it won't work with that.

Greetings,

Georg
