Display Drivers and copy-paste Issue Ubuntu 17.10

Hi Team,

Recently i had upgraded my motherboard and processor to AMD 3.5 GHz AM3+ FX-6300 Processor
Gigabyte GA-78LMT-S2PT Motherboard.

1.After the re-installation Ubuntu 17.10 i am not able to copy paste or create a new folder in any of my drives.
2.After the installation i have observed the display is incorrect as per this resolution 1600x900 , let me know how to get the compatible display drivers of above mentioned board processor. ( I have already checked in ‘software update tool’ for ‘additional drivers’ and it is not showing any drivers )

If anyone has the solution PLEASE do let me know, i am having a lot of problems.
