I experience this problem too since my upgrade to Quantal, and use "sudo service lightdm restart" when it happens. But since a few days, i have a new problem : my whole graphic environment sometimes vanishes completely when i press the ESC key while reading my e-mails with thunderbird ! I use "sudo service lightdm restart" and all is up again. Don't know if this new problem is related to the first. (my conf: dell e6420 - SSD)
