View Full Version : [ubuntu] dual display breaks unity

January 29th, 2012, 02:50 PM
I find that most of the time, when I plug in my Dell 19" monitor with an HDMI lead, unity can't decide on the configuration; it will switch between different resolutions, and setups every 2-30 setusecond until I either ctrl-alt-backspace or unity crashes so I have to hard boot. Alternatively all the windows decorations and unity get killed.

Currently I don't think the Radeon graphics card is working properly, but I'm not sure.

When I tried my Radeon HD5450 card with dual-monitors I was pleasantly surprised at how it all seemed to "just work". But that was with the default open source driver which fulfills my needs with this card. I have noticed threads detailing problems with dual-monitors and the proprietary video drivers so, are you using the proprietary fglrx driver and, if so, how well or otherwise did your HD 6630M card work with the open-source one?
