I have Xubuntu 18.04 on a little HP laptop which is very similar to the 14 inch HP Stream 64 gb eMmc, n4000 cpu, except that it has a RJ 45 port.   It came with Windows 10S which I converted to Windows 10 Home.  This is my first ever laptop and so far it is going very well and totally silently.  It is so low powered there is no risk of coil hum/whine!   Its UHD 600 graphics are roughly the same as the Pentium G3240 HD graphics so it plays hd youtubes just fine.

Anyway, I now have it running Xubuntu 18.04 and have also bought an ex lease Dell 22 inch monitor as the laptop screen was just about satisfactory.   Before updating a full install of Xubuntu took only 5 gb of disk space which is good when you only have 57 gb to use.  It gets to the login screen in under 20 seconds and shuts down in less than three seconds.

I have changed from light-locker to gnome-screen saver as light locker caused a bad screen freeze.   Gnome-screen saver has worked flawlessly for over 3 weeks.   I had problems with VLC freezing just like it did on my old PC running 18.04, so I mostly use smplayer for watching dvds.   Smplayer works perfectly but the developers removed support for menus as it had been very difficult for them to get it working properly.   From experimenting with different dvds this means that smplayer will start the dvd immediately, or sit at the menu for about three minutes and then play the dvd perfectly, or sit at the menu forever and not play at all.  Smplayer is very nice especially for hd video from Youtube.

So far the only dvd player that I have found having working menus is VLC so I am giving it another try.   So far it has worked perfectly but it is too soon to cheer because I installed it only few hours ago.   I am hoping that some update may have fixed the freezing issue because VLC worked perfectly in 16.04.3

Although gnome-screen saver is working perfectly for me there are plenty of posts on forums saying the opposite!  Although I have the laptop on Xubuntu I made two restore images using Clonezilla in case I want to go back to W10 - which actually runs very nicely.

I forgot to mention that the Dell monitor comes with 4 usb 2 powered ports which is very useful as the laptop has only 3 usb ports.   The Dell monitor usb ports might be in near new condition as they felt quite tight the first few times I used them.  This would make sense if the previous user had a Dell business pc on their desk with plenty of ports at the front.
