+Recent machines (Fedora Core 22 and later) may use ''dnf'' instead of //yum//, and PackageKit. Use the following commands for cleaning the cache:
+  * **dnf** (/var/cache/dnf): ''dnf clean all''
+  * **PackageKit** (/var/cache/PackageKit): ''pkcon refresh force''
 It's also a good thing to clean the //journal// (note: limiting the journal size probably has to be done only once)

 If you want some details about how the graphics are handled by the current installation of you VB (i.e. **is your VM using the graphics card of the Windows host** or is it running is it use the sloooow software mode?), you can use the following commands
-  * **glxgears**: if things work correctly, you will get a window with smoothly rotating gears (you can make the window fullscreen and check that it is still working) and the terminal will display some frames per second statistics
+  * ''modinfo vboxvideo'' will give you some information about the video driver provided by VB. Theoretically, //vboxvideo// should also appear when you type ''lsmod''

     * You may get some warning and error messages, but you should be good if the gears are rotating smoothly
