xrandr state with two displays fails to resume when waking from suspend

[Christopher Barrington-Leigh]

On latest karmic, I use an external monitor in an extended desktop cnfiguration.
This used to work nicely and resume the confguration when waking from suspend.
But recently (ie after updates), the two monitors (laptop LCD and external monitor) appear in a strange mirrored state when waking from suspend.

xrandr command reports the correct state, even though that is not what is visibly in effect (both the external and the LCD monitors are showing the wrong thing).

Running the xrandr command to reconfigure to the correct state has no effect. Instead, I must switch to some other state using xrandr (or the gui for it) and then return to the correct (extended) desktop for it to actually have an effect.

You wrote about updates, so I add the regression tag.

Sorry, I won't add the regression tag since this package hasn't been updated since 51 weeks.

Hi,
  I don't think you have the logs to show what graphics card you have; however if it is an i945GM then I think you might have
this bug:

https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/404509

if it is a 945gm please mark it as a dupe.

Yes, the graphics circuit is a GMA950. I am tentatively marking this as a duplicate of 404509, but that means reopening that bug.

[Christopher Barrington-Leigh (cpbl)]

Whoops! The title of this bug is wrong. I was running the latest 10.04 update, not "karmic". I just got the name wrong.

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
