Xorg freeze

[Simon Volpert]

The system freezes (display shows last image before the freeze) at random intervals with no obvious indications and has to be hard-rebooted. The logs seem to be cut off at the moment of the freeze, and the system becomes unreachable from the net.

Simon Volpert, thank you for reporting this and helping make Ubuntu better. As per http://www.toshiba.co.uk/innovation/download_bios.jsp?service=UK an update to your computer's buggy and outdated BIOS is available (2.30). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then please mark this report Status New.

Thank you for your understanding.
