maybe i was trying too many things at a time, but one day i kept connected to internet and downloaded several choices of packages, each "collection" of no more than 20 MB, more or less.
In one of these i choose components referring to Xorg. all so fine.
Later i shut down the computer, and wanted to start up again, but instead of showing the login screen my computer remained black.
in the log screens (ALT+F1, F2, /var/logs/messages) + the help of some live CDs i found that xorg was looking for some inexistent components. After some tries i copied from the new Kurumin 7.0 live CD its xorg folder to /var/lib/xorg/modules/
worked fine with this one !!
When starting up again i checked in Pisi Again, and updated the Xorg Main package, which was showing up as "possible update".
well, my critics / suggestion (i don't know how, but..): maybe for some critical packages there should be a stricter check for requirements/dependencies in Pisi. In my case probably: FIRST install Xorg, and LATER its addons.
/** as well as NOT neccesarily update the kernel if i want to install some stuff which is not security or hardware related.. **/
ok, so far.
But i keep trying Pardus, and also will the next version
