Cannot switch back from dual-screen to single-screen 2:10.0.0-3000743-3ubuntu1

Hi Balint,

I have the same issue but then in reverse. I cannot swich from single monitor to dual or tripple "full screen" mode. The screen blinks but nothing happens :)

Looking in to it right now :)

Ok, its a know issue with vmware 12.1.1: http://pubs.vmware.com/Release_Notes/en/workstation/12player/player-1211-release-notes.html

> After you exit full screen mode on a multi-monitor system, an Ubuntu 16.04 virtual machine does not refresh properly
> On a system with more than one monitor connected, if an Ubuntu 16.04 virtual machine is in full screen mode, using all displays, the virtual machine does not refresh its display properly after you exit full screen mode.
> Workaround: If you experience this issue on an Ubuntu 16.04 virtual machine, restart the virtual machine. If you want to switch the virtual machine to full screen mode, use a single display only.

Status changed to 'Confirmed' because the bug affects multiple users.

Although listed in the 12.1.1 release notes I'm pretty certain I experienced this issue before upgrading also. It would be nice to hear if anyone using 12.1 experiences the same issue.

Also the version of open-vm-tools you list is unsupported, the version supported at release is 2:10.0.7-3227872-2ubuntu1.

I can confirm that I see this issue with 2:10.0.7-3227872-2ubuntu1

I downgraded my VMware player to 12.1.0 build-327244 i use the open-vm-tools package 2:10.0.7-2ubuntu1

I still cannot switch from single to dual or tripple. When i try this i get the following error in my kern.log:
###########
May 12 16:56:29 DEV08 kernel: [ 4968.928257] [drm:vmw_sou_crtc_set_config [vmwgfx]] *ERROR* Multiple framebuffers not supported
May 12 16:56:29 DEV08 kernel: [ 4969.247008] [drm:vmw_cmdbuf_work_func [vmwgfx]] *ERROR* Command buffer error.

The weird thing is, i could copy this from my ubuntu guest to my windows 7 host. The other thing that is weird, afther i try this, my mouse is 50% off, it seems that the mouse capture assumes dual screen instead of single screen. when i click the "single" screen button in vmware player everything goes back to normal.

I installed a second (clean) VM with ubuntu 16.04 for testing and it had exactly the same issue!

I just downgrade my vmware player to 7.1.4 build 3848939 and open-vm-tools 2:10.0.7-3227872-2ubuntu1 This doesn't solve the issue. i am getting exactly the same error messages.

I did some tests and have no idea of they have any relevance at this point but i thought i share them maybe they are useful for someone.

Since i guesse that there are more ppl out there with windows > vmware player > ubuntu 16.04 guest i would think that there would be more reports but there are not.

- Disabling 3d acceleration for the vm - no difference
- gnome / LXDE / openbox / ubuntu default (unity?)
-- When using unity? the screen stretches but same error no frame buffer.

I looked upstream on the freedesktop.org bug tracker and there doesn't seem to be a related bugs :(

this appears to be fixed for me now with a recent update. Not exactly sure which one but I believe I recently installed a Kernal update.

Yes, it seems to be fixed for me too.
