Package: synergy
Version: 1.8.8-stable+dfsg.1-1
Severity: important
Dear Maintainer,
Issuing the following command either before or after starting synergys:
xinput --set-prop <mouse id> "Coordinate Transformation Matrix" 3 0 0 0 3 0
0 0 1
Where <mouse id> is the ID given by "xinput --list" for my trackpoint
mouse device.
Results in the following problem(s):
With the synergy client computer configured on the left side of my synergy
server, synergy does one of the two following behaviors when sliding the mouse
off the left side of the server screen:
1 - The mouse immediately wraps around to the right side of my server display
rather than showing up on the client.
2 - The mouse is captured by the client display, but cannot be moved on the
client, however, when in this state, keyboard input from the server is
correctly routed to the client machine.
Restoring the matrix to its default values on the server:
xinput --set-prop <mouse id> "Coordinate Transformation Matrix" 1 0 0 0 1 0 0
0 1
fixes the problem.
I also tested this with version 1.4.18 of synergy installed on both computers
and experienced the same results.
I flagged this as important since I am left with a choice of usable mouse
performance (xinput scaling for proper acceleration on my trackpoint can
only be achieved by use of the transform matrix) or working synergy.
Additionally, the transform matrix is modified by some systems in order to get
proper orientation of mouse output when using rotated screens. I tested
a 90 degree rotation using the following matrix values:
0 -1 1 1 0 0 0 0 1
and synergy again broke. This problem makes synergy completely unusable in
some working environments.
Client machine used for this is running Ubuntu 16.04.4 LTS, xenial, with the
Synergy 1.8.8 package installed from the Ubuntu "artful" archive.
