Code: Select all
$ sudo add-apt-repository ppa:voria/ppa
$ sudo apt-get update && sudo apt-get upgrade
$ sudo apt-get install samsung-tools
$ sudo apt-get install samsung-laptop
$ sudo reboot
The first time I did that, it messed up a bunch of stuff from doing apt-get upgrade. Based on the googling i did, I needed to re-install the OS so that's what i did. The second time i was more careful. First I did apt-get update, then I added the repo, then I did update again. I skipped the upgrade and then installed the two programs and rebooted. When it came back, my nice UI was gone and replaced with a traditional ubuntu one. How can I get the nice one back? The problem is mostly the start menu. Screenshot is here:
I want to know how to fix the menu, but also why update and upgrade is causing so many problems. I plan to use this as my main OS but if I cant do apt-get update without causing an issue, then maybe i need to move back to ubuntu. Can you guys help me fix the problem and explain what I need to do in the future for this not to happen?
