See http://askubuntu.com/questions/480758/ubuntu-12-04-screen-issue-after-updating/480939#480939 and https://communities.vmware.com/message/2388970#2388970.

More users are reporting the same problem with VMware virtual machines after the update.

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 !!)
