Comment 3 for bug 1367870

It seems to me that this problem appears much more frequently with Chrome, but I've had it also with Firefox. It's only been a couple of weeks though, everything has always worked fine for me until a system update two weeks ago. I have a Radeon HD 4350/4550.

To speak very bluntly, it makes Ubuntu almost unusable for me with at least one Xorg freeze per day when I don't use Chrome - with Chrome it more like a freeze per hour of usage.
