I just upgraded to 10.10 64-bit from 10.04 64-bit and my external monitor is no longer working properly. Using the "Monitors" function in preferences, it does recognize my monitor and does in fact activate it, but the total available screen real estate is only increased by 10-15 pixels (i.e. my mouse moves to the external monitor, but it stops after 10-15 pixels). Thinking that something went wrong with the upgrade, I backed up my data and did a clean install from CD after format and the problem is the same.

Please let me know what system details other than lspci I can include to help diagnose the problem. Thanks!

I just tried putting the primary display on my external monitor and turned my laptop screen off and the display works properly by itself on the external monitor. Could this be a video memory problem?

I solved this problem by using the Intel 945 drivers from the Xorg-edgers PPA

Add http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu as a PPA URI in Package manager.
