dual monitor: won't restore resolution after suspend/resume

[Alexander Sychkov]

Binary package hint: xorg

I have a laptop with 2nd monitor connected to VGA port.

Steps:
1. Close the laptop, Ubuntu suspends.
2. Open the laptop. Unbutu successfully resumes.
3. Input password

Result:
resolution is 1024x768 on both monitors. Same image on both monitors.

Expected:
1600x900 on external monitor, 1366x768 on laptop monitor, as I set before suspend+resume. Layout is the same as before suspend+resume.

Note:
When I boot the laptop with monitor connected, at login screen resolution and layout is wrong, but as I log in, it sets automatically according to my settings. I think the same must happen after suspend/resume. For now, I have to maually set resolution every time, it's very bothering.

[Pavan PT (pavan-tekur-gmail)]

I have the same issue as observed above. The monitors are set to clone display overriding my original configuration. My laptop is a Thinkpad X200 and monitor is a Dell U2311.

My Ubuntu setup is updated to all the current patches and upgrades till 11 March 2011.

Hey Alexander,

Hi, have you had a chance to test if this bug is still present in natty?

If it does (and if you're the original reporter), please boot into natty
and run the command:

  apport-collect <bug-number>

which will update the bug with fresh logs and tag the bug as affecting
natty. (It is best to run this right after reproducing the problem.)

[bugbot (bugbot)]

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.

I'd like to reopen the bug. I have two laptops, both running Ubuntu 10.4. On the Asus eeepc the resolution is reset correctly after sleep, but not on the Dell Inspiron. On the Inspiron, the laptop resumes from sleep in 'mirrored' mode.
