Help, im lost, cant run installed packages

post #1 of 4
Thread Starter 
So I finally installed linux on my netbook, been meaning to do it forever. I installed Peppermint LInux on my Asus eee 1005HAB. Finally figured out getting the wireless working and now I am just poking around, learning the in's and out's. I went into the software manager, took a brief look through, installed some packages that looked interesting, went to look at what I downloaded and only a few programs show up in the software menu. I managed to locate where they were installed /usr/bin...but even tracking them down there it asks me if I am sure I would like to run the executable, but once I say yes, still doesnt run.

Sorry for the rambling, feelin pretty dumb...just trying to remember, not dumb...ignorant:thumb:

Try opening up the terminal and typing "/usr/bin/[the-name-of-the-program]" or just "[the-name-of-the-program]"

does it work then? if not what does it say?

/usr/bin/compiz
/usr/bin/compiz (core) - Error: Screen 0 on display ":0" already has a window manager; try using the --replace option to replace the current window manager.

Thanks for the help, not looking forward to looking back on these posts in a few months thinking "my god what a stupid question"

The first thing you need to learn with Linux is not to care about where programs install themselves. If you're using a package manager (rather than downloading and compiling / installing stuff manually - which is a big no-no unless you really know what you're doing!) then all of this will be managed for you and all you need to do is click menu items or, absolute worse case scenario, just type the app name (without any path) into the terminal.

The reason for this is because everything will be in big generic folders like /usr/bin and those folders will all be mapped to something called a $PATH environment variable. Don't worry if this is all double dutch to you; it really doesn't matter if you understand it or not - as it will all just work behind the scenes and thus you shouldn't need to fiddle with any of these things.

So, going back to your original question: you just need to find the appropriate icon in your desktops menu or type, compiz in the terminal (no path). However installing the rest of Compiz's applications (plus Emerald), if you haven't already, then run the Compiz Manager which will put an icon in your sys tray. From there you switch your "Window Manager" over to Compiz.

Compiz can be a little bit fiddly to set up at first (you're essentially hacking a different rendering engine into the back end of your desktop), but once you understand the following, it's pretty easy to work around:

On a Linux desktop you have the following: Xorg->Window Manager (WM)->Desktop Environment (DE).
In laymans terms, Xorg is the "kernel" of your desktop. Then you have the window manager and desktop environment which, essentially do as they say on the tin. The WM processes all your windows, mouse movements, etc. The desktop environment is your icons, menus etc. It's a bit like on Windows 7 where the WM would be Aero and the desktop environment would be Explorer.exe as that's the desktop shell.
