Hi, I started using Kubuntu 15.04 around five months back and recently I encountered a problem when I updated my graphics driver[1]. Currently I’ve Nvidia 860M Graphics driver in my Lenovo Y50-70 laptop. I tried [2] and even tried updating and upgrading the whole system by logging in through tty1 using ' sudo apt-get update/upgrade' using the LAN cable but then it didn’t work. The screen says blank for a long time and after that I've to forcefully turn it off. I then tried the following commands in tty1- rm -r ~/.kde rm -r ~/.cache rm -r ~/.config/plasmarc and then kbuildsycoca5
Then I tried editing the boot up option as in one of the links which was editing the ‘/etc/default/grub’ file and changed the GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash nomodeset” and then saved the file and the ran ’sudo update-grub’ but still it turned out to be unsuccessful. So the next option which I found was reinstalling the whole version but then it’d cost me a lot since I’m working on it.
