Can just log in to Classic Desktop with no effexts otherwise get just empty screen with wallpaper only

I'm not sure if this is a right project, but others are definitely not :-)

After upgrading to Natty I can no longer log "normally" into Ubuntu desktop. The only thing what appears after the logging screen is my wallpaper and the screen seem to be transparent. I mean when I click a mouse something happens like a program launch or so.

I can only log with No Effects option.

I attach my system data presented as 'lspci -v'
