After some search I come to know about the existing issue between graphics driver for AMD/ATI graphics cards and Ubuntu 16.04 LTS here Unfortunately, I am using Ubuntu 16.04 LTS on laptop with AMD/ATI graphics cards.

Now, I decided to upgrade to Ubuntu 18.04 LTS, (please comment on this) hoping that the problem will go. So, I need to backup important folders. The new problem I'm facing is that external hard drive cannot be detected by the computer, which make backup impossible. Any help is appreciated.

Regards.

Thank you.

Yes, I checked the /media, used lsusb, remove and re-insert and also use different drivers. But I couldn't see it.

Regards
