after suspend xorg uses very much CPU.

[Daniel Holm]

After I've had my laptop suspended it got really slow - and it's brand new and not as slow after fresh boot.

I saw that the xorg process used almost 100% of the CPU. After I've restarted compiz it got lowered, so it actually might be that instead, and not the xorg packade.

Daniel Holm, thank you for reporting this and helping make Ubuntu better. As per http://www.sony.co.uk/support/en/content/cnt-dwnl/SVP1321M2E/list an update to your computer's buggy and outdated BIOS is available (R1044V7). 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.
