(sorry for my English)
I experience this issue on Ubuntu 12.04 and 14.04 with updated kernels
(3.2.0-67-generic and 3.13.0-30-generic) and different DE's.
I'm on a vCenter environment so I don't use vmPlayer. I use vSphere Client
5.5.0 build 1474107 on vCenter Server 5.5.0 build 1476327. My VM's
Upgrading the Virtual Machine Version from 7 to 10 fixes this for me on
all my VMs.

Chris,
Below, the download link of an Ubuntu 12.04 VM image with the split screen
issue.

I don't think this is an OS host issue because I reproduced this issue
on Windows and Ubuntu 14.04 hosts, and Rojer on a modified Ubuntu 12.04
I disabled the kernel option quiet.
After switching to tty console, dmesg | grep fb_fix returns :

Oh dear...
It seems like we're narrowing it down at least, but it definitely seems
to be limited to older VMWare versions and possibly only Windows hosts.
@cedricg91 would you be able to follow up with Thomas Hellstrom's
request for a VM image? In fact, would you be able to just put it up
Chris, as mentioned above, my host is a modified Ubuntu 12.04 (with a newer
3.13 kernel), amd64.
i'm afraid i cannot post exact build details because it's an internal corporate
build.
my player version is 6.0.2 build-1744117, guest os is a vanilla 12.04 amd64

Hi Chris.
my host is a custom distro derived from Ubuntu with custom 3.13 kernel, guest
is a plain 12.04 x64.
i have performed steps 1-6, this is how i isolated your patch:
1) sudo apt-get install linux-source-3.2.0=3.2.0-63.95
2) make -j3 deb-pkg, this produces
Hi chrisfriedt,
I have the same issue on Ubuntu 14.04 host.
I found this issue on VM created with an older version of vmware player
(version 5.0.x) that generate VMs in version Workstation 6.5-7.x
virtual machines. This issue is still present even if I use these VMs
with the lastest version of
removing (commenting out) vmw_write is not enough, the following patch
still produces split screen output. http://pastebin.com/FYJEULF3
and to confirm what cedrig91 is saying - yes, my VM is also quite old.

Chris, Rojer,
On my Ubuntu 12.04 VM (3.2.0-64-generic kernel) I deleted
/lib/modules/3.2.0-64-generic/kernel/drivers/gpu/drm/vmwgfx/vmgfx.ko and
display seems to work fine now. There is no split issue and the screen
resolution is dynamically configured (I have VMwareTools-9.2.2-893683
installed).
Hmm... I'm still skeptical that this code path is even touched.
Thomas Hellstrom is removing the write to BYTES_PER_LINE in any case,
because it is a read-only register.
The most decisive test would be to log entry into this function call,
like I said in my last message, but that would really
booting kernel with the following patch http://pastebin.com/NBeRfwYJ and
running dmesg | grep fb_fix comes back empty, so vmw_fb_check_var is
not invoked.
however, in my setup there is a reliably reproducible link between
changes to info-fix.line_length and the split screen issue: comment out
I added a logging statement in the kernel to function
vmwgfx_fb.c::vmw_fb_check_var() using the following patch :

Not sure atm, but you might need to remove quiet from the boot args to
see KERN_INFO messages.

Hi cedricg91,
While I don't have a Windows 7 PC handy, I have tested using the
following two host environments.
* ElementaryOS (VMWare Player 6.0.2 build-1744117 / 3D acceleration OFF)
* Mac OS X Mountain Lion (VMWare Fusion 5.0.4 1435862 / 3D acceleration ON)

The issue is with xorg-video-vmware, not vmwgfx.
