After two weeks looking for and trying solutions by upgrading kernel from 3.2 to 3.3.4 and 3.3.6, changing drivers but the system still completely freezes. Finally I install ubuntu 12.10 and it works for two days without freeze. I havent installed Bumblebee yet. I will install it after a week to see if graphic card driver causes freeze issue.
Again here is my configuration: - Dell XPS 14 Ultrabook 1.7Ghz Core i5 - HDD 500GB, SSD 32GB stores ubuntu 12.04 - Graphic card 1GB Nvidia 630M -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.
