Ah! Well, I realized I missed something reading the man pages about xrandr and what I need to do is this, but it also fails:
$ xrandr --addmode DVI1 2560x1600 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 (RANDR) Minor opcode of failed request: 18 () Serial number of failed request: 27 Current serial number in output stream: 28 Any hints would be greatly appreciated. tia, Robby On Tue, Jun 2, 2009 at 3:39 PM, Robby Findler <[email protected]> wrote: > Hi all: I'm having some trouble getting my apple cinema displays to > run properly.
