Hello,

I've had the identical problem (to Bug #945006 18 & 31) on several attempted installations of Ubuntu 12.04. Actually, no flickering but the wrong screen resolution until I change the refresh rate from 60 (incorrect) to 75 (correct). Then uncontrollable flickering. The wrong screen size I can live with but the flickering disables the machine (Dell Optiplex 745).

I dual boot with Ubuntu 10.04 (where the graphics card works perfectly). The 12.04 file system is still intact. If anyone could advise me where I can change the refresh rate in 12.04 from 10.04, I'd be grateful for the workaround until a better solution is available.
