i have no solution for you.
... but black screen seems like xorgconfig problem.
a quesion: what happens when you press ctrl+alt+F2.
if you see the loginpromt in testmodus then pardus has boot correctly.
and the problem is anything with graphic card driver.
Since Pardus also disables the keyboard, PS/2 or USB no matter, then such a standard procedure obviously doesn't work. However I forgot to mention that when booting in text mode it looks like the main system is functioning. In most cases the system doesn't totally lock up, because if pressing the power button it starts to shutdown processes just as it should. In one of let's say 20 attempts it might even boot up correctly. Of course settings for all this devices will be found in xorgconfig, so I suppose I have to try to get it to stay in init 3 mode, even though my editing of grub hasn't worked as I hoped yet.
Still it confuses me: what on earth can possibly change by itself between two sessions? In the two occasion that I could get the system up running again I see nothing wrong. There must be some incompatible weak link somewhere.
A funny note is that before this installation the machine has been running Fedora 5 - the hd I previously mentioned - and a while ago I added a module of extra RAM and didn't bother to memtest it. Before this installation however I choose to run memtest and that extra module proved to be faulty, spitting out errors like a flood. So I put back another module of less MB and memtested and certified that the system was stable again. So what's funny? The Fedora 5 installation has been running with that faulty module for at least 2 months, been updated, even the kernel, and pushed hard in some applications, and still it hasn't even once failed to boot and no application has crashed. When I now run it it definitely looks like it's totally intact. That's pretty impressive I would say, but therefore even more makes my problem with Pardus a mystery.
I'll try to find some extra time tomorrow, or I move on, because I don't have time enough at this moment.
