The same behavior observed with kernel v4.4 and v4.14.

This sounds like WAI:

In the moment you unplug the external display, all windows get moved to the internal display. After reconnecting the external display, the windows will stay on the internal display.
So if anything this should be a feature request and it should ask for saving and restoring window positions across screens (until explicitly moved by user) while window is open. 

Thanks for your reply.

But in R65 version, once i reconnect the external display, all window positions were restored. 

In all versions (R65, 67, 68), external display which is set to primary mode still restored. 

Thanks,
Kiran

Only the difference observed is window positions. In R65, all windows moved to HDMI. While in R67, all windows retained in internal display (extended mode).

This is WAI in new design.

Windows are moved to "primary" displays (not necessarily means internal) when external display is disconnected. If you're using external display as internal, windows on internal dislays are moved to "primary" display coordinates. When you replug the same display, these windows stays in
the primary display and that's what you've seeen until 66.


This has changed recently, and windows are moved back to the position when display was connected.
In above scenario, windows are moved back to secondary displays, which is internal display.


This is probably wontfix, assigning to oovanieva@ for triage juset in case.

This bug has an owner, thus, it's been triaged. Changing status to "assigned".
