OK for these. Regarding your issues, I think that if you also post a
question in Ubuntu users mailing list
-https://lists.ubuntu.com/mailman/listinfo/ubuntu-users, and in Ubuntu
Forums: http://ubuntuforums.org, you will get more answers, than
posting in Lubuntu users mailing list only.

I have no experience of LTSP clients, so someone else may know more
about your questions.

As far as I know, until recently, there were two kinds of drivers.
Kernel ones, and X.Org ones. I think there is an effort to eliminate
the second ones, however I do not keep up with all free software
As far as I know, X.Org is now automatic (I do not know whether it has
anything to do with KMS), however it still respects xorg.conf if it
For example, if you install nvidia proprietary driver (nvidia-current
and nvidia-settings packages), or amd (fglrx and fglrx-amdcccle
packages), you should run nvidia-xconfig, and aticonfig --initial
after instalation, respectively. These programs create a necessary
xorg.conf for these drivers to work optimally.
I do not know if these drivers include X.Org drivers, or only kernel
