I am facing the same problem but more frequently. I did not have this freezing problem with Ubuntu 12.04 on my Dell XPS L502x. Once I installed 14.04 this freezing problem started. Sometimes to unfreeze entering into console mode and then going out works else need to reboot the system.
I have been looking for a solution for quite a while now and have not found a fix. I am contemplating going back to 12.04! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1341539 Title: Dell XPS L502x Ubuntu 14.04 freeze sometimes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1341539/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
