Correct Display configuration. Errors while trying to arrange displays
- by David Russell Parrish Bojrquez
I am trying to set up my tv with my laptop trough a VGA cable. The display application in Ubuntu throws a lot of errors to me and I have given up in trying to do it myself.
I try to apply the 1920 1080 display.
The selected configuration for displays could not be applied
Requested size (3200, 1080) exceeds 3D hardware limit (2048, 2048).
You must either rearrange the displays so that they fit within a
(2048, 2048) square or select the Ubuntu 2D session at login.
And Also this:
Failed to apply configuration: %s
GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._gnome_2drr_2derror_2dquark.Code3:
Requested size (3200, 1080) exceeds 3D hardware limit (2048, 2048).

Please Help.

No I don't see anything when connected to 1920 1080 because the setup fails before actually applying.
Yes there are other resolutions which do work. I believe the problem has something to do with the rotation it is set up. My Ubuntu Display application has only clockwise and counterclockwise options for the TV display. I really don't know why this is happening.
Basic procedure: Plug in cable, did not get the resolution I wanted. Changed settings, applied them. Re-peat until desired display is shown. I'm not a computer illiterate, really it baffles me that this is happening.

Note that VGA says left and indeed it is, but no other option was available in the display. Also, note the TV1 unknown connection which I have no idea what it is.
Note, also, that this has nothing to do with the display since W7 on the computer works fine and since while boot up, and also, before starting session in ubuntu the rotation is normal.
I'll also mention that I HAVE re-installed Ubuntu since I had posted this question from a Live CD of 12.04 LTS. And that before the posting of the question also using 12.04 before another backup that I had to do, the VGA setup was fine without any problems.
