Subject: Re: [PATCH 1/1] drm/vmwgfx: correct fb_fix_screeninfo.line_length

At least one source has reported that vmwgfx_fb.c::vmw_fb_check_var()
is not even a code path that is traversed when the bug occurs (i.e.
inserted unique log message -> never seen in logs).

Also, everyone encountering the bug seems to be on a slightly older
version of VMWare Player. It does not seem to occur with "modern"
versions of VMWare Player, and might even be limited to Windows hosts.

So I think at this point, I can conclusively say It Wasn't Me™.
However, I am a bit concerned with this bug, so I'm going to follow up
on it within the Ubuntu community and help out in any way that I can.

In any case... I do have a pretty cool patch that enables (something
like) double-buffering on vmwgfx_fb - care to see it!!??

Hehehe... I'm serious! :-)

Cheers,

C
