Since I installed Linux on my laptop about 1,5 years ago (Dell e6410, first Ubuntu 10.04 LTS, now Xubuntu 12.04 LTS both 64bit) I have had unpredictable system freezes.
It happens while working on the laptop and suddenly everything freezes: mouse does not move anymore, screen does not update, Ctrl+Alt+F1/F2... to go to terminal does not work anymore, closing laptop lid does not make system go in suspend,... only remedy is holding power button to shut down laptop and restart it. Once I also tried to ping the box from another machine and that also did not work. There is also nothing in syslog, kernel.log etc that indicates freeze as far as I can see. Sometimes this happens twice a day, sometimes once every 5 days but it always comes back. I'm using my laptop about 8 hours a day during weekdays. I keep it up to date with the provided LTS updates but this issue keeps on being there. I like the speed and usability of my system but It is just annoying not to be able to trust the stability of my machine. (I had suspend/hibernate/resume issues before but those are solved now) I see no difference in frequency of freezes when comparing Ubuntu 10.04 vs Xubuntu 12.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 completely freezes frequently.

No other TTYs can be started. Mouse doesn't move. Keyboard doesn't react. The only solution is hard reset. Seems to happen on a variety of configurations, including nVidia, ATI and Intel graphics. If you are still able to TTY or SSH into other sessions, move the mouse or use the keyboard, file another bug. Thx. Joris V. (brains). Update: 5/21/2012 Updating the kernel to 3.3.6 as suggested by Michael in #91, the system seems stable, no freezes yet in 5-6 hrs of using and watching videos for couple of hrs. Original description: I recently installed newly released ubuntu 12.04 LTS 64 bit version on my desktop. And it is frequently freezing, for the first few hours it ran smoothly and when I started watching videos it started freezing randomly. I have to use hard restart every time. Initially it was only during videos but now even during normal browsing it is freezing. I am using on board graphics and do not have any graphics card installed. Can someone please help me here, I really love the new looks of 12.04 and it bugs me not being able to use :( Below is my hardware configuration: Processor: Intel CORE i3 processor (2nd generation) Board: Intel® Desktop Board DH67BL Ram: 4GB Graphics: On board HDD: 500 GB Please let me know if you need more information, or any specific logs I can capture (and how).
