- mention what actual resolutions work

- F11 up2date

- card (lspci), and driver is in use ?

- resolution you are trying ?

- does the system you are plugging into feed EDID back to your PC ?
(most installed projection systems don't, only RGBHV are sent to proj, 
no returns).

- are you on the VGA connector / input

- if it's no EDID
   (try plugging cable straight into projector), it might be recognised
   System Admin Display|Hardware|Monitor Type = ?
   select either the matching display, or generic display of resolution 
the projector is capable of.
Logout, ie make X restart, and then in System Preferences Display set up 
your monitor.
