This question already has an answer here:

Yesterday my computer stayed open all night and then when battery was empty it turned off. Its normal for my computer. But when at morning I turned it on, there wasn't login screen. It crashed everytime. After reinstalling Xorg, lightdm, ubuntu-desktop and doing some other things login screen appeared. But after login I can see only my desktop and System crashed warnings that appears in ubuntu from times when unity came. In guest mode everything works well. I created new user and assigned him as admin (All privilages) and logged in to his account. Now I'm writing from that user account and everything works very well. So, How I can restore my main account?

Selecting Unity Plugin from ccsm not worked (login to user account, go to tty1 and entering export DISPLAY=:0 and then ccsm + switching to F7). + reinstalled ccsm Half of space in SSD is empty, so its not memory problem. Wallpaper in its place :D

install unity-tweak-tool terminal : sudo apt-get install unity-tweak-tool

reset unity by running this command : unity-tweak-tool --reset-unity


First of all needed to install graphic card driver for intel hd 4000 from different source:

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update && sudo apt-get upgrade

Then opening ccsm again and select unity plugin. Accepting and enabling all warnigns, there will be a lot than usual. After that unity menu will be shown. After reboot everything will work as before but there will be a lot warning messages. Another problem is to solve that errors.

I have no idea how after reboot unity can crash in such way.
