Ubuntu is great, but here are some tips to fix some issues that I regularly encounter.
If its a logitech mouse, install solaar
with Unity/gnome extensions, sudo apt-get install solaar-gnome3
.
Then unplug the mouse and restart the system.
Or try lomoco
to manually configure.
This is an odd bug that has effected people for a long time, but hasn't been fixed.
If you notice your machine heating up, check you system monitor and stop
gvsd-smb-browse process, don't kill it.
There is 100 fixes available online, but all are sort of sketchy and odd.
The best option: install samaba, sudo apt-get install samba
.
It seems Ubuntu doesn't have the full package, and once you install it, the bug seems to go away.
