[Bug 577640] Re: nVidia TwinView resolution not supported by X

 

Btw, I expect this still affects Precise, but if someone would like to
verify that, it would boost the priority of this bug for our development
work.

If you don't want to install Ubuntu Precise, it should be sufficient to
boot a Live USB session, configure the monitors, and see if it is
working properly now.    You can get the current Live USB desktop image
at http://cdimage.ubuntu.com/daily-live/current/ and create a USB boot
drive using usb-creator.

Title:
  nVidia TwinView resolution not supported by X

Status in “gnome-desktop” package in Ubuntu:
  Triaged
Status in “gnome-desktop” source package in Lucid:
  Confirmed

Bug description:
  [Problem]
  The proprietary nVidia driver seems to be treating the two 1920x1200 monitors as one 3840x1200 monitor. This resolution is then not supported by the X Server, causing the error message on login: 

  'Could not apply the stored configuration for monitors
  X Server does not support size requested'

  However, the display still works as expected.

  
  [Original]
  Since upgrading to Lucid, I am getting the following dialog warning on login:

  'Could not apply the stored configuration for monitors
  X Server does not support size requested'

  I think this is related to the reported dimensions when using the
  NVIDIA proprietary driver with dual heads in twin view. See
  http://ubuntuforums.org/showthread.php?t=1477254 for details.
