Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself.

Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again.

My wild guess is, should this be related to driver? Below are my detail system information:

$ lspci

02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01)
