X error when running synergy in client mode

[Václav Šmilauer]

This is a regression from 13.10. Whenever I run quicksynergy/use/start, I consistently get this in the terminal:

2014-04-24T15:40:17 INFO: Synergy 1.4.12 Client on Linux 3.14.0-031400-generic #201403310035 SMP Mon Mar 31 04:36:23 UTC 2014 x86_64

The synergy session does not work, no attempt to connect to the server is made.

Actually this bug is trivially reproducible here by saying

$ synergyc --name falx --no-daemon 192.168.1.12

Status changed to 'Confirmed' because the bug affects multiple users.

It looks like this bug affects me as well (this is my first bug report in launchpad, if I missed some information, please let me know). I would like to add that it used to work and then after one of ubuntu updates stopped with the following error.

$ uname -a

I should say that after the following update of my ubuntu 14.04 system, everything gets back to normal!

[Václav Šmilauer (eudoxos)]

I resolved the issue by installing all *mir* packages -- I noticed in ps -A that Xorg was run with some mir option. After uninstalling all libraries related to mir, everything works smoothly again. (Keyboard lag was also resolved by that, which is not a part of this bugreport).

This report should be kept open (perhaps re-assigned to mir) until it is resolved properly, though.

[Andrej Ricnik (a-ricnik)]

Same issue, but with the server process dying.

Thanks Václav for your work-around; that worked a treat (and fixed the keyboard lag, too ;}).
