Hi nthebay,

Thx for using Fusion.

Do you use Fusion 7 Tech Preview build or Fusion 7 GA build? Pls let me know the Fusion build number.

And what kind of OS do you use? How many external monitors do you connect? For now, we just can support three displays including main display.

Pls also attach the display topology, it can be got from Apple -> System Preference -> Display -> Arrangement.

Hi nthebay,

There is some code change in this area after Fusion 7 Tech Preview, one big difference is that now we require the guest topology to be correct. So pls let me know your display topology as my above comments, let me check whether we support the guest topology. Thx a lot.

Yes, Thx a lot. I think the topology should be supported....

Pls let me know your display information, by running below cmd at the terminal of the host, then attach the output here:

system_profiler SPDisplaysDataType

And pls try to reproduce the problem(enter unity, and get the topology not support msg), and then attach below two logs here?

1. /Users/<your user name>/Library/Logs/VMware Fusion/vmware-fusion.log

2. Right click your VM, and choose "Show Package Content", then find vmware.log

I'll use above information to open a internal bug to get dev's help, Thx a lot for your effort in advance.

Hi!

Jumping in on an existing discussion here instead of creating a new one; I updated to VMWare Fusion 7 yesterday, and are having this exact same issue getting Unity mode to work. Checking my logs, I see this:

2014-10-21T08:45:51.143+01:00| VMware Fusion| I120: IsTopologySupported: Guest screen size limit: 8192x8192, 2 displays max, bounding box memory limit: 67108864 bytes.

2014-10-21T08:45:51.143+01:00| VMware Fusion| I120: IsTopologySupported: The topology has 4 monitors, which exceeds the current limit of 2 monitors.  Returning false and setting powerOffNeeded = true

When attempting to go into fullscreen, I get a mirrored configuration on all my displays - and Windows only sees one screen. In addition the resolution is way off, so in addition everything looks horrendous.

My topology consists of the laptop screen (MBP Retina), two 24" screens and one 21" screen in non-mirrored mode. This used to work just fine in VMWare Fusion 6, and after updating I'm forced into doing my Windows-work (which is a big chunk of my workday) inside a single window on a single desktop. Having a limit of two monitors supported in a topology seems mindblowing, I hope there are imminent plans to increase this? Having two external monitors hooked up to a laptop cannot be a weird use-case, there are three display ports on a MBP. I really hope there is a quick solution to this, because at the moment I'm regretting the upgrade.

The solution outlined at http://www.jonathanmedd.net/2014/03/using-more-than-one-external-monitor-in-vmware-fusion-6.html allows me to use all 4 displays in proper fullscreen at least, so it's possible to make this work until a better solution is in place by VMWare.

Similar situation here.  I use Windows 8.1 Pro for development, running within VMWare Professional Version 7.0.0 (2103067) on a Macbook Pro Retina 15-inch, Late 2013 with 2 external monitors connected via min-display adapters through Thunderbolt ports.  I updated from Mavericks 10.9.5 to Yosemite and at the same time updated to the latest VMWare Professional.   I the View menu item for VMware used to say, "Use multiple displays for Full Screen" and now says "Use Single Display in FullScreen".  Checking it causes Windows to mirror across monitors instead of extending like the previous behavior.    Unity also fails as others noted.  A quick fix for this would be greatly appreciated.

Hi nthebay,

Have you ever try plug external monitors out, power off the VM (not suspend, but a full shutdown), restart Fusion, then plug external monitors, enter into unity again? Will that work?

And I've open an internal bug for this, fyi.

Thx a lot & Nice day.

I attempted this now (same issue as nthebay), and it seems to allow Unity mode - and seems to be a good workaround for now.

Thanks.

Great to know! Thx a lot for your trying.

I also tried that last recommendation.  Neither multiple displays nor Unity work on my system.

Here's a shot of my VM and host configuration/layout:

Oh, and I received an update for VMware Fusion, so I'm now at 7.0.1 (2235595)

Nothing new to add, just digging.  This bug has ruined my productivity by constraining me to a single display.  Does anyone know if there are beta versions of Fusion, which have a fix?
