I recently installed Ubuntu 18.04 in a Dell inspiron 7559. I had a lot of trouble with the installation of almost any distro but this time it seemed that everything worked just fine. The first couple of times that I closed the lid and re-opened it, everything seemed to work fine, but now it doesn't. Namely, after it resumes, opening apps by clicking them is not a posibility any more. Do you have any ideas of how I can fix this bug? Note that the laptop bares a NVIDIA card and I have installed the proprietary drivers.

Note that sometimes it freezes, sometimes it does not...which I find it even more weird..

  • The developers should fix the bug, not you. (unless you're an ubuntu developer). The most useful thing you can do is filling a bugreport. – Ipor Sircer Nov 18 '18 at 21:27
  • Yeah, but it might be something that justs needs a fine tuning and not an actual bug..... – hal Nov 18 '18 at 21:33
  • Something's needed a fine tuning is also a bug. Developers should do the fine tunings - this is the meaning and the goal of a distribution. – Ipor Sircer Nov 18 '18 at 21:39
  • Please post the output of lspci Let's make sure this isn't a hybrid laptop before we file a bug. – eyoung100 Nov 18 '18 at 21:50
