Hi everyone,
Scenario:
HOST: VMware Workstation 10.0.2 build-1744117 on a physical host running Kubuntu Linux 12.04.4 LTS, Precise Pangolin, completely updated to this date (June 07th), kernel 3.2.0-64-generic #97-Ubuntu SMP Wed Jun 4 22:04:21 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux. Host was rebooted after last update; operating fully, no problems.
VIRTUAL MACHINE: VM runs Kubuntu 12.04.4 LTS, Precise Pangolin. Desktop: KDE. It was working normally until this morning; previous update a few days ago.
VMware-tools updated to the latest version.
This morning, I updated this VM; previous kernel was 3.2.0-63; after update it became 3.2.0-64. The only updates available today were: the kernel, and OpenSSL. Nothing else was updated.
After the update, I rebooted and ran vmware-tools-config.pl.
WHAT HAPPENS AFTER THE KERNEL UPDATE?:
Now, the VM screen is split in two halves. Whatever I open on the left-hand side (say, a console) is mirrored on the right-hand side as a "phantom" image. If I move the cursor over the right side, icons that were hidden by the phantom-copy will show through. This makes using the VM almost impossible, with several windows and applications.
1. I ran vmware-tools-config and rebooted the VM: no effect.
2. I resized the VM window; maximized and clicked back to normal size; changed wallpapers and themes; to no avail.
3. I did the same steps on another host with VMware Workstation, and exactly the same problem happened to the VM there. Same mirrored / split screen.
4. Updates applied to several physical hosts (with reboots) caused no problems to them. Only VMs are affected.
Is this a problem with the virtual graphics controller in the VMware Workstation?
For now, I switched back to the previous snapshot and it is working normally. I cannot update the kernel, though.
Any help will be appreciated.
PT.
This problem is being reported by other users at the askubuntu forum as well:
vmware - Ubuntu 12.04 screen issue after updating - Ask Ubuntu
There is another thread here, under the Player forum:

The other users are also running VMware.
PT.
I used my VM previous snapshot to reproduce the problem.
Previous kernel: 3.2.0-63. VM running ok.
1) I applied all updates (including openssl) but NOT the kernel. After rebooting, the VM screen is OK.
2) I updated again (only the kernel packages, version 3.2.0-64 were pending: complete kernel, headers and kernel image) and rebooted: split / doubled screen shows up!
3) I ran vmware-config-tools.pl in other to generate modules for the new kernel and rebooted: the split screen persists. Not solved.
4) also tried a full power off / power on: the problem persists.
It seems to be definitely a kernel 3.2.0-64 - related issue.
Suggestion: apply all updates (the openssl update is critical), but skip the kernel packages for now, until we get a fix from VMware or the Ubuntu team.
(AND: ALWAYS create a snapshot before you update anything !!)
Hi
Welcome to communities.
then its related to kernel package or kernel does not support his hardware .
Please try to upgrade videos driver too if available .
Hi,
have the same problem, have tried much but always the same problem
I have enabled the grub menu at startup and then select the previous kernel (3.2.0-63-generic), screen is ok.
There is no video driver that has to be updated.
Just confirming that I too have the same problem. 3.2.0-64 causes the screen mirroring, but 3.2.0-63 does not.
3.2.0-65 is also problematic.
For remedies, please see the thread "Guest display split into identical panes"
