Thanks for reporting this bug and helping to make Ubuntu better. This is an odd problem, it might be specific to your hardware.
Could you help us diagnose the problems by running the commands lspci > lspci uname -a > uname You should find two files in your home folder, lspci and uname, please upload them to this bug report as attachments.
