This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release.
Again, you're testing with the i810 driver. This functionality is not expected to work with the i810 driver. Are you sure you're testing what you mean to be testing?
I will retest with intel driver.
With intel driver, I now get the wrong resolution on both screens (1680x1680 according to xrandr). It does not cycle through the states but just turns on the external display and primary display with the wrong resolution. When trying to get back to a good resolution, I unplugged the external display and hit fn-f7 again with not effect. I then switched to vc1 and back to vc7 (where X was) and X crashed. I will attach the log.

This request was previously evaluated by Red Hat Product Management for inclusion in the current Red Hat Enterprise Linux release, but Red Hat was unable to resolve it in time. This request will be reviewed for a future Red Hat Enterprise Linux release.
Apparently the expected results when hitting Fn+F7 has changed. From what was explained to me by an X developer, Fn+F7 does not cycle through the displays. Now it triggers X to rescan the display ports. Then X configures the resolution for the larger of the two displays. Thus resulting in the display with the smaller max resolution to only show part of the desktop. This resolves all issues in this bug except for the crash. I will file a different bug for that when I see it again.
