I saw in my Ubuntu 14.04 installation that there is a process called wineserver.
Is that a default process/program when you install Ubuntu? I have another machine running the same OS (14.04) and don't have this process running.
PS.: I don't have wine (run win apps) installed in both machines.
wineserver is a component of wine. It shouldn't be present in a default clean Ubuntu installation. Someone either manually installed it or it was installed as a dependency of another package.
Please try the following:
Where is wineserver?
Use which to find out:
$ which wineserver
/usr/bin/wineserver
winserver's full path is /usr/bin/wineserver.
What package "owns" that file?
Use dpkg -S:
$ dpkg -S /usr/bin/wineserver
winehq-devel: /usr/bin/wineserver
/usr/bin/wineserver is there because it is part of package winehq-devel.
Why is that package installed? (You'll need aptitude for this, or you can also use apt-cache --installed rdepends <package>)
Run aptitude why:
$ aptitude why winehq-devel
i playonlinux Depends wine | wine-development
i winehq-devel Provides wine
winehq-devel was manually installed (the line starts with i A for automatically installed packages). It's also a dependency of package playonlinux, so if I uninstall winehq-devel I have to uninstall playonlinux, too.
If you don't need it, remove it.
sudo apt-get purge winehq-devel
When was it installed?
dpkg maintains a log in the files /var/log/dpkg.log*
$ grep "install winehq-devel" /var/log/dpkg.log*
/var/log/dpkg.log.1:2016-04-04 14:01:31 install winehq-devel:amd64 <none> 1.9.7~ubuntu16.04.1
Of course, replace winehq-devel with the actual name of the wine package installed in your system. As you can see, winehq-devel was installed on 2016-04-04 14:01:31.
There's also the apt logs located at /var/log/apt/history.log*. I found this in file /var/log/apt/history.log.1.gz:
Start-Date: 2016-04-04 14:01:00
Requested-By: carvalho (1000)
Install: ..., winehq-devel:amd64 (1.9.7~ubuntu16.04.1), ...
No surprise, I intentionally installed winehq-devel.
Good luck!
