I have tried to install unity 8 on my ubuntu 16.04 following this link

after installing I tried to use unity 8 and it ended in a black screen, nothing was being displayed, so that I have restart my Ubuntu and logged in on default unity (7.4) so my wifi is not working anymore, I have changed to my windows 10 on dual boot and the wifi on windows is not working too... I am googling a lot and I can't find a fix for that, anyone could help?

I have already tried sudo systemctl restart network-manager but it doesn't work

  • If it doesn't work in both OSes, it is not a Ubuntu issue and certainly not related with the attempt to use another desktop environment. It's either a coincidence that the hardware became defective (or in need of reseating) when you were experimenting or something else happened and you're not telling us... Perhaps you inadvertently switched off the WiFi? –  Aug 09 '17 at 15:54
  • my wifi is enabled on bios, I am a programmer so I know at least the basics xD the only thing I did was installing unity 8, its very odd... – Wagner Moreira Aug 09 '17 at 16:42
  • Please [edit] and include the hardware information. Check with lspci(for internal WiFi cards). If you can't see it there then it's defective or dislodged (yes, it happens). In that case remove and reinsert it and it should work right away in both. And it can be enabled in BIOS/UEFI and yet switched off by a special key or some FN+Fx. –  Aug 09 '17 at 16:47
  • @MichaelBay thanks, I added the hardware information, there is a ethernet controller but no wireless controller... is that the point? I'm on a notebook it can be fried? I bought this notebook 6 months ago and the wifi stopped working when I installed unity 8, it's odd... :// – Wagner Moreira Aug 09 '17 at 17:28
  • Yes, it should be there regardless of blocks. Really not good but the first thing to try is re-seat the card (you may want to check a couple of videos if you haven't done that before). –  Aug 09 '17 at 17:40
  • Unity 8 is at best an alpha quality piece of software. It's no longer developed or supported. Don't bother installing it... too late I guess. I'd troubleshoot the wireless problem from Windows first. Once you get it working there it may very well work in Ubuntu. – heynnema Aug 09 '17 at 18:16
  • @heynnema do you know any other interface that is beautiful as unity 8 and don't broke my ubuntu? – Wagner Moreira Aug 09 '17 at 18:44
  • @WagnerMoreira since GNOME is Ubuntu's future, starting in October, I'd install ubuntu-gnome-desktopand that will give you a head start. You might try uninstalling/purging Unity 8 first and see what's left. – heynnema Aug 09 '17 at 18:53
  • @heynnema by installing gnome desktop there is any chance of broke my unity? – Wagner Moreira Aug 09 '17 at 19:56
  • If you're primarily going to use GNOME, no problem. If you're primarily going to stick with Unity, you should read my question/answer at https://askubuntu.com/questions/903373/unity-problems-after-installing-gnome-desktop-ubuntu-gnome-desktop for some good information. – heynnema Aug 09 '17 at 19:59
  • @heynnema I'm with gnome shell now and I liked it, thanks! – Wagner Moreira Aug 09 '17 at 21:00
