Unity Launcher and top panel overlays full screen mode

[EarlsFurniture]

When running a guest in full screen mode, the Ubuntu Unity launcher and top panel overlay the guest screen. This behavior was introduced immediately with the 4.3.16 update. I discovered this issue right after an update to 4.3.16, tested on another machine before and after the update and was able to repeat the issue. The issue did not exist in 4.3.14.

Marked as GUI/Compiz since Unity is a compiz plugin. Otherwise devs would know better where this issue lives.

Marked as major because the left and upper portions of the underlying guest window (usually containing icons, menus, tools in some apps) are inaccessible in this state.

I'm not sure any particular log is relevant, but I'll be happy to upload one if needed.

I can also assist with testing if need be.

[Michael Thayer]

Confirmed. For now disabling the mini-tool-bar works around the problem.

Some more relevant information: I too have this issue, but also the screen is misaligned in multi-monitor setup. (See the attached screenshots of a windowed and full-screen guest.)

The positioning is a bug in Compiz/Unity.

I am using Gnome Shell (Host = Fedora 20).

I seem to also have issues with full screen and seamless mode with the latest Vbox.

I have multi monitor setup, 1st monitor - 18" = 1360x768 ; 2nd monitor - 21" = 1920x1080.

If the guest starts in Windowed mode it works fine.

If I do CTRL+F I cannot use the guest. Getting back to windowed mode (after you try to put the vm in full screen or seamless mode) does not work as the guest goes outside the window area in the wrong monitor (primary) even though the window is in the secondary monitor.

Guest = Win 8.1.

Sorry for sounding dense, but could you please explain that again?

You cannot switch modes to full screen or seamless. It doesn't work.

[Michael Thayer]

Your comment sounded more to me like you could switch to that mode but couldn't get out of it again. It was the bit about the guest going into the wrong monitor that I did not get. Are you talking about the guest window moving? If so though what do you mean by the guest moving to the primary monitor while the window (the guest window?) is in the secondary?

I am attaching a screenshot.

This is after switching back to windowed mode.

Window (inside is black) is in Monitor 2. Guest is outside the Window in Monitor 1.

[Michael Thayer]

Thank you. Are the black bars something you edited into the image manually or something on your screen?

The black bars on the left came with the screen shot because the 1st monitor is smaller than the 2nd monitor.

1st monitor - 18" (or 19") = 1360x768 ; Left side ;

2nd monitor - 21" = 1920x1080 ; Right side ;

By the way, anyone affected by the shifted-screen-position-under-Unity problem should feel free to add a "me too" to the Launchpad bug report I linked to above, or (better) select "this affects me too" on the bug report page.

[Michael Thayer]

quickbooks: I tried running a single-screen Fedora 21 guest under GNOME Shell started as "gnome-shell --replace" on a dual-screen Ubuntu 14.04 host with screen set-up as below. I was able to enter and exit full-screen with the mini-toolbar enabled or disabled without any problems. Admittedly this was with a development build and development Additions. Any thought about other potential relevant differences in your set-up?

[Jeffska]

I can confirm similar issues in a vanilla Gnome 3/Mutter environment (Arch Linux) as well. Whatever full-screen related changes that were made as part of 4.3.16 are causing all kinds of havoc.

[Michael Thayer]

Jeffska: similar to what quickbooks describes? And both, does disabling the mini-toolbar make any difference?

Mini-toolbar was already disabled.

Can you try running Windows 8.1 guest?

Here is the ISO for F20 with updates to around September 2nd: ​https://dl.fedoraproject.org/pub/alt/live-respins/F20-x86_64-LIVE-DESK-20140902.iso

I have now downgraded to VBox 4.3.14.

If you want I can test a development build if it fixes this annoying issue: https://www.virtualbox.org/ticket/12610

Confirmed. For now disabling the mini-tool-bar works around the problem.

It seems while this does work to enter full-screen mode, there is then no way out. The Host+F or any other Host+ combo to enter any other mode does not work. As well, and this may be of course another issue, the Host toggle to capture/release the keyboard does not work at all. (which may be why I can't switch modes) The keyboard is permanently captured by the VM, but does not function within the VM either - effectively a dead keyboard.

I tried Seamless and Scaled mode and had the same problems. Scaled has no menu, and Seamless won't work with the mini-toolbar. So I can enter the VM in any mode, I just can't switch back to my host after that, and no matter what, I don't get any keyboard functionality.

So this work-around is a no-go.

I've downgraded to 4.3.14 via debs from the virtualbox.org site, but can test other builds if need be.

[Michael Thayer]

I would also be interested to know whether disabling 3D, if it is enabled, makes a difference for anyone who commented here. EarlsFurniture: is the failure of host key combinations something reproducible? I am asking because I use Ubuntu with Unity on my development system and do not see this.

The Latest test build - 64-bit Linux, r96212 - still has the multiple monitor issue.

Including with 3D disabled?

[Frank Mehnert]

Still an issue with VBox 4.3.18? Actually VBox 4.3.18 contains a possible extradata setting which allow to change the behavior for Unity, please check the user manual.

[NSky]

how do I turn on "extradata setting which allow to change the behavior for Unity"?? Was googling for 30 minutes but found nothing.

Thanks, it works!

[Frank Mehnert]

There is a workaround in VBox and in the meantime, Unity is also fixed. Closing this ticket.

[Michael Thayer]

Ubuntu now have a fix available for testing for Ubuntu 14.04. Could someone using that test their package and update the Launchpad ticket? Thanks!

[Justice]

Regression perhaps? With Ubuntu 15.04, I can still interact with the (initially hidden) launcher buttons at the extreme left edge of the screen.

To be clear, the buttons aren't visible, but a click there brings them to the foreground.

This happens for me whether or not the VB mini-toolbar is enabled.

[Justice]

I am still seeing a variant of this issue with Virtualbox 5.0.6 on my asymmetric multimonitor setup on Ubuntu 15.04. The Unity launcher and menubar are hidden behind the fullscreen Guest screens, but accept clicks after working outside of VB for a few minutes and then returning.

I have filed launchpad bug 1503767 against Unity. If you observe similar issues, please indicate so on the Launchpad bug.
