I really don't know why, but I have my Ubuntu the same, I only have installed all updates by synaptic and the related bug back.
"Every time I use my laptop with Ubuntu 10.04 Lucid Lynx, it simply overheat and suddenly shuts down/off. This generally happens after 30 min of use. All packages are updated. I have not installed the ATI drivers, so I'm using default." ** Changed in: linux (Ubuntu) Status: Fix Released => New -- Laptop overheats and suddenly shuts down/off using Ubuntu 10.04 Lucid Lynx https://bugs.launchpad.net/bugs/575559 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
