http://bugzilla.suse.com/show_bug.cgi?id=1158470 Bug ID: 1158470 Summary: synergy: Mouse pointer can't be moved back to server after switching to neighbor Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: Other OS: Other Status: NEW Severity: Major Priority: P5 - None Component: X11 Applications Assignee: bnc-team-screening@forge.provo.novell.com Reporter: martin.wilck@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I'm observing erratic behavior of synergy in my setup under Leap. TL;DR: It's fixed by upgrading to synergy-1.9.1-lp151.61.3 from X11:Utilities. Setup: server "artemis", left:

eDP-1 connected primary 1368x768+0+1152 (normal left inverted right x axis y axis) 294mm x 165mm DP-1-1 connected 1200x1920+1368+0 left (normal left inverted right x axis y axis) 518mm x 324mm

This is the laptop screen plus one monitor in "portrait" orientation. client "apollon", right:

DP1-1 connected primary 1080x1920+1200+0 left (normal left inverted right x axis y axis) 530mm x 300mm eDP1 connected 1368x768+2280+1016 (normal left inverted right x axis y axis) 310mm x 170mm

Another vertical monitor plus the screen of the 2nd laptop.

From left to right, I have "artemis" laptop screen, portrait monitor of "artemis", portrait monitor of "apollon", "apollon" laptop screen.

The links section in synergy.conf looks like this:

section: links artemis: right = apollon down = zeus apollon: left = artemis down = zeus zeus: up = artemis left = artemis right = apollon end

(computer "zeus" is switched off). Now I start synergys on artemis, synergyc is running on apollon. I slowly move the pointer on artemis from left to right until it reaches the right edge of the portrait monitor. I'd expect the cursor to move on "apollon" now, but this does not happen. It vanishes on "artemis", but it's not visible on "apollon". When I move the mouse back left, still nothing happens. I can't get the mouse pointer to move back to "artemis" screen. I have to ssh to artemis and kill synergys to get a working mouse pointer back. Here's what happens in the synergys debug log when moving the mouse from left to right:

[2019-12-04T22:54:18] DEBUG2: event: MotionNotify 2563,1158 [2019-12-04T22:54:18] DEBUG2: event: MotionNotify 2565,1158 [2019-12-04T22:54:18] DEBUG2: event: MotionNotify 2566,1158 [2019-12-04T22:54:18] DEBUG2: event: MotionNotify 2567,1158

at this point the right screen border of "artemis" is reached, now we start generating events for "apollon":

"onMouseMoveSecondary" gets basically the same relative step over and over again, causing the pointer to move monotonically to the right (I made but minimal movements with the mouse at this point), until...

Here, the *right* edge of apollon's monitor is reached although I sure as hell didn't move the mouse there. Comparing the same log for synergy 1.9.1:

Here it seems that right after entering "apollon"'s screen, a number of MotionNotify events is discarded, and later on, onMouseMoveSecondary() calls seem to "correct" previous movements. For the user, this feels correct. Also, the mouse pointer is well visible in on "apollon", moves as expeted, and can be moved back to the "artemis" screen just fine. I've been trying to figure out which commits changed this behavior between v1.8.8-stable and v1.9.1-stable, but nothing caught my eye. The 1.9.1 version has already been submitted and accepted to Leap 15.2. I'd like to suggest to submit it to 15.1, too. -- You are receiving this mail because: You are on the CC list for the bug.
