After installing Freya I noticed that my laptop hangs very often. I can however do Alt + Ctrl + F1 and back Alt + Ctrl + F7 to get it working again. Could someone tell me how can I find out what is causing that and how to fix it?

  • You could try to run the top command in the terminal 1 (Alt+Ctrl+F1) and see wich process is consuming too many resources (if there is one) – ikaro Sep 8 '15 at 6:03

    @ikaro if switching TTYs is a solution, then it is likely not a problem with a runaway process. I had a similar issue with gala at one point which was later fixed by updates. This sounds more like a bug in the Window manager to me. – RolandiXor Sep 9 '15 at 22:11
  • Most resource consuming processes are chrome, gala and Xorg. – turntable Sep 9 '15 at 22:23

    Without further information, the question is too broad. For good reference, it's worth giving a look at the system logs help.ubuntu.com/community/LinuxLogFiles – Giulio Sant Sep 13 '15 at 9:54
  • did you got any solution? try open tty1 using.Ctrl+Alt+F1and run sudo service lightdm restart please comment if solved – Ravan Oct 10 '15 at 12:47
