My PC is running slow after changing the driver












0















I have a Dell inspiron-15-3552 which comes pre-installed with Ubuntu 14.04 LTS. It has Intel hd 400 Brasswell graphics. From the system setting >software and updates> additional drivers I clicked the the other one from available options. and applied changes.
After the loading it was still showing applying changes but I closed the tab. When I restarted my laptop ubuntu detected an internal problem. and it is now running slow and animations are not smooth. Now I can't revert the changes cause those options that are available before are not available now. I am new to Ubuntu. Please help me to fix it. Thanks.
