Public bug reported:
The default version of the xserver-xorg-input-vmmouse package in Ubuntu
12.04 is 1:12.8.0-1. When Ubuntu 12.04 is installed as a guest in VMware
Workstation (tested on 8.0.3) or VMware Player (tested on 4.0.3), the
mouse behaves rather erratically. For example, if you *slowly* move the
mouse down 1 pixel, the mouse will actually move several pixels down,
then sometimes a pixel or two to the right, then sometimes back up. The
end result is a very un-smooth user experience. This is very visible by
opening a new un-maximized window and dragging it slowly across the
screen. Rather than it being a smooth movement, the window will jerk
around slightly. This causes huge issues when navigating menus.
Sometimes the guest will think the mouse has moved off a menu.
I am running VMware Workstation 8.0.3 on a Windows 7 x64 host,
installing the standard Ubuntu 12.04 amd64 desktop version.
-------------------------------
Steps to reproduce:
1. Install Ubuntu 12.04 as a new guest operating system inside either VMware
Workstation 8 or VMware Player.
2. Once installed and logged in, run xev in a terminal.
3. Move the mouse slowly but smoothly downward along the Event Tester window
while monitoring the console output.
What should happen:
1. The x,y coordinates reported after the "time" field should increment /
decrement smoothly. For example, is moving the mouse downward in the Event
Tester, the x coordinate should stay relatively stable (a change +- 1 is
acceptable), while the y coordinate should increase proportional to the speed
that the mouse is moving.
What actually happens:
1. The x coordinate will change +- 3 or so pixels, even though no horizontal
movement is occuring.
2. The y coordinate will not increase linearly. For example, if moving the
mouse downward starting with a y coordinate of 60, the next few events might
show the y coordinate as 61, 62, 63, 64, 60, 63, 67, etc...
----------------------------
I have confirmed this is an issue with vmmouse 12.8 by rebuilding the
12.7 package from the Ubuntu 11.10 source repo, removing the 12.8
package, and installing the newly build 12.7 package. After this has
occured, the mouse moves smoothly, and the events reported by xev make
much more sense. The x coordinate does not change while moving the mouse
straight down, and the y coordinate increases linearly without skipping
back up.
