I have a flat screen LCD monitor and the refresh rate is set out of range. I have no idea what 12.04 thinks it's dealing with. Occasionally I get a visible screen for a second or so which after many such second-long flashes lets me change to resolution to 1024x768 which, though not nice (native 1280x1028) is readable and thence to 1280x960. I have just "upgraded" from 10.04 and found I can no longer set the refresh rate manually. Why is it that "upgrading" so often leads to loss of functionality? Installing Mate restores all the functionality of 10.04 (including the world daylight indicator) and as a bonus removes Unity. So I can now run my monitor at nice resolution and refresh rate. Now all I have to do is find a way to keep the settings as default so I can actually see the screen when I log in. "Set as default" doesn't seem to work :-( Time to look into xrandr I suppose. If the problem is known as an upstream bug and it makes 12.04 almost unusable without Mate shouldn't it be fixed?
