TV Display is corrupt after switching resolutions

This information applies to the following system configurations:

  • ATI Proprietary Linux Driver 3.7.1 and later
  • TV Out enabled in fglrxconfig
  • Big Desktop or Dual Head monitor layout is used

This issue does not occur in Clone Mode or when the TV is the only connected display.

Upon using the resolution keyboard shortcuts (ctrl-alt-+) or (ctrl-alt--) to switch resolution of the XFree86 Desktop, the display will be off center or completely corrupt.

The TV display is not usable in this state and it is not possible to get back to a stable resolution once this has happened. A restart is required.

ATI Engineering is aware of this issue and is investigating. Updates will appear on this page when they become available.
