In case you need to revert back to your original Ubuntu AMD Radeon drivers you can remove the PPA driver installation using the below commands:
$ sudo apt install ppa-purge
$ sudo ppa-purge ppa:oibaf/graphics-drivers
Linux uses this mechanism to throttle the spamming of log events, decreasing the likelihood of a denial-of-service attack.

good guess its a driver problem, the drivers for your card is not included in Ubuntu, see this from AMD/ATI it includes the software you need
