Disappearing of second screen on W7 guest (FS mode) => Fixed in SVN

[Evgeny]

In fullscreen mode (2 monitors on host WinXP & 2 monitors on guest Win7 with WDDM and Aero enabled) after number of idle (in guest) minutes second screen disappears. Mouse starts behave uncorrectly (look like X resolution for mouse is still like in dual screen mode but scaled to single). Sometimes Win+L(guest) and login after helps - second screen appears but some times not. Also topmost windows on host overlapped by guest in fullscreen (it was ok in one of prev versions).

Also appears in VB 4.2.4 And one more thing - second screen do not redraws after it was restored from minimized state.

Thanks for the report, and sorry for the delay. We've reproduced it here and will investigate it shortly.

[Frank Mehnert]

This problem will be fixed in the next major release.

[Frank Mehnert]

Fix should part of VBox 4.2.12.

[Frank Mehnert]

No, that's wrong, sorry.

[Evgeny]

So waiting for the next major release... :)

[Frank Mehnert]

The fix is contained in VBox 4.3 Beta 2, please give it a try.

[Evgeny]

Not sure that will be able to check it now... Will try in nearest time.

PS: By the way found that login to virtualbox.org over oracle access manager fails if using Opera (v.12.12) :) IE, FF looks well but Opera fails displaying "Oracle Access Manager system error. Contact to sys.adm."...

[Frank Mehnert]

Fixed in VBox 4.3.

It still happens, second screen disappears.

VirtualBox: 4.3.20-96996~Debian~wheezy

Host: uname -a Linux workstation.aulix.com 3.13-0.bpo.1-amd64 #1 SMP Debian 3.13.10-1~bpo70+1 (2014-04-23) x86_64 GNU/Linux

Guest: Windows 8.1

Workaround steps:

1) VirtualBox: choose "Switch to Full Screen"

2) Windows: reconfigure displays, say change to "duplicate" mode and then change back to "extend" mode.
