Helo again!
Like I've said in my post above I had problem with blue screen on login on Zephyroth 10.5.2, so I download Leo4all and give it a shot. And after putting all graphical kext and reboot I've seen QE and CE on right resolution for first time. I was very happy and played with it for some time, but after shutdown (no restart) and start again it booted into my desktop with artifacts and hang (even dock doesn't start). I've tried to install again all graphical kext, but now i get the same as on Zephyroth-blue screen and after while blue screen with mouse coursor (probably in right resolution).
Guys plz help! What can cause damage?
