Ive installed Ubuntu 15.10 on a Dell Inspiron 13-7353.  Things work okay overall, but two critical problems have appeared.First, occasionally, when the laptop wakes up from sleep the screen will come on and I can see the desktop, but things are frozen.  No keyboard entry or mouse cursor movement. Even the caps lock LED wont toggle.A second problem has popped up after the last few updates.  After waking from sleep, and using for a minute or so, the trackpad cursor freezes.  If I have a terminal window up and in focus, I can still type in commands.Would anyone happen to have some experience or advice to resolve these issues?  Ive tried to do an upgrade from 15.10 to 16.04, and my attempts have been unsuccessful.  The upgrade seems to make it through, but on reboot things never make it to the login screen.  I have to fire up Clonezilla and restore my 15.10 backup.  I keep the 15.10 install updated with the latest stable kernels and updates.Are there any Dell device drivers available to try?Is there a better/tested distribution and version of Linux to use?  Id actually probably prefer Debian, but when I tried that disto I couldnt get the wireless to work.
