System doesn't stop after last upgrades installation

Hi guys referring at end of post " http://www.64studio.com/node/1074 " I had writen : Hi Dave The message of nvidia-installer is the same also after the last updates proposed of few minutes ago that I have installed because there wasn't the message of partial upgrade proposed and I have think the problem was solved. After sudo apt-get update and sudo apt-get upgrade all upgrade was installed but there's problem with " linux-image-2.6.29-1-multimedia-686 and linux-rt " leavede not configured cause problem with dependences. I hope that I haven't create nay problem in my system and now first I look to grub-menu.lst and after try to reboot. Reboot is ok This is not true : system doesn't stop and after closing GDM on screen there is this message : gdm [4311]:Glib CRITICAL:g_hash_table_lokkup_extended assertion 'hash_table!=NULL' failed gdm [4311] Warning:Request for invalid config Key xdmcp/Enable=false[100.807280]System Halted But system remain in this state for a long time and after 5 minutes I reset my system and reboot in win XP to stopping PC. Have you soem idea for this ? Bye Guido
