Ubuntu 14.04 (Trusty Tahr) is very slow after install Or Upgrade from 12.04
So the other day, I downloaded Ubuntu 14.04 LTS Trusty Tahr and installed it in my dual boot box. I was using earlier release Ubuntu 12.04 LTS and it was fine after installation. But this time there was a surprise.
Just after installation, when I logged on, the system was horribly slow. The graphics responses was so slow that minimizing one window Or opening the terminal takes like forever to load. I was wondering what would be the problem, because earlier 12.04 was just fine and I just did a fresh install so disk space also sufficient. At this point let me tell you that, my system configuration is pretty old – its having AMD chipset and 2 GB of ram.
After couple of frustrating tries, I figured the problem. Its the Unity desktop effects rendering problem with my Graphics card nVidia GeForce 6150se nForce 430.
During installation, Ubuntu installer assigned the graphics driver ‘Nouveau display driver from xserver..’ and my nVidia Graphics card have no clue about it. Thus creating this horrible effect.
Installing correct nVidia Driver solved the problem. If you are facing the same problem, follow these steps:
1. Open Terminal.
2. Run these commands in sequence.
sudo apt-add-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install nvidia-current nvidia-settings
3. After above 3 commands completed, open software & Updates window.
4. Go to additional Drivers tab.
5. You should be seeing just installed Driver.
6. Choose the driver and click apply changes.
I hope this should solve this slow response problem with Ubuntu 14.04.
