Thank you for taking the time to report this bug and helping to make Ubuntu better.

Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709

Thanks for the bug report. The first problem I can see here is that you are using graphics packages from the 'oibaf' PPA which are unsupported and often buggy.

Please remove that PPA using 'ppa-purge', reboot, and then if the problem continues please open a new bug.
