 "Hello, I'm new to Xubuntu and..." <- Your release details is always helpful.  You can use `dpkg -i <package>` to install a *deb* package... but that will require all *depends* requirements for thee package to be already installed OR you adjust the command to install them as well.  You can also use `apt` to install a already downloaded package (*give a filepath instead of simple package name*) which has the capacity to attempt to

[08:31] <nikolam> I have a mousepad process, using 100% of one core and not visible anywhere on Xfce desktop. 
[08:31] <nikolam> I have put machine into standby and back before and it resumed from suspend this morning.
[08:32] <nikolam> What would be the best way of debugging that 'undead' mousepad and ret it's debug information? 
[08:37] <anonymous> hi
[11:45] <nikolam> I attached with gdb on 'mousepad' process that was left on, after standby/resume with large cpu usage, now doesn't use large cpu time anymore but is still alive and can't see it in X session 
[11:45] <nikolam> Any suggestion how to debug it, catch info, before killing it, to get debug data why it is still on ? 
[11:53] <nikolam> Ok, I just killed it, maybe another time.
