However we are unable to help in this case because you are using an unsupported PPA ("oibaf") for your graphics libraries, which is not from Ubuntu. We often find that's the cause of serious graphics bugs. So this bug will be marked as invalid. Please uninstall that PPA and then if you continue to have problems feel free to open a new bug. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1850551 Title: Xorg freeze Status in Ubuntu: Invalid Bug description: I recently upgraded to ubuntu-18.04 and the screen starts to freeze randomly.
