Upgrading from Ubuntu Gutsy (7.10) to Hardy (8.04) in MacBook: Screen Resolution – x server does not support the xrandr; problems with dual and extended screen

Changing Screen Resolution Problem

After updating from Gutsy (7.10) to Hardy (8.04), I noticed the utility for changing the screen resolution (System -> Preferences -> Screen Resolution) does not work anymore in Hardy as it did in Gutsy. It gave an error message:

The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.

Xrandr Problem

Likewise, when I tried xrandr -q on the command line I got the following X BadRequest error:

$ xrandr -q
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 151 (RANDR)
Minor opcode of failed request: 6 ()
Serial number of failed request: 9
Current serial number in output stream: 9
