Ubuntu – Display Text Too large on startup – possible GUI driver issues


So, I had a few issues installing a fresh Ubuntu 20.04 with respect to the GPU driver. I was having issues with screen size, that were eventually fixed. Now, with a recent update, I have an initial start up and log on screen that is abnormally large. Once I am in the GUI I am faced with a screen with appropriately set sizes (as set in settings), except for text (as seen in the top ribbon in the image below):

The large text option in the universal access is not turned on and, strangely, when it is turned on the text resizes back to normal. This isn't a massive problem, as this fixes the issue, but it is a hassle as it has to be done each startup. I suspect it is a driver issue but I don't know where to start. I am new to these forums so, please be kind and let me know what information you need to answer the question. It will be provided promptly.

I did just want to add that it seems the update has affected the mouse as well. Transitions between windows seems to occasionally disable the mouse click momentarily. This is an issue in dragging and dropping, which will occasionally cut out or display unpredictable behaviour. I am fairly certain this isn't an issue with my mouse and the issue emerged just as this update occurred.

  • Second Edit:

    Quoting from Brian Murray on the launchpad forum for this bug:

    "The verification of the Stable Release Update for mutter has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions."

    First Edit:

    It seems that a fix has come out of the launchpad forums. It has worked for me. Unhold the original hold below, if you did indeed use the below original solution. If not, do not use this command...

    sudo apt-mark unhold libmutter-6-0

    and download/install the package from the PPA as follows...

    sudo add-apt-repository ppa:ci-train-ppa-service/4265.1 sudo apt-get update && sudo apt upgrade

    The original answer I gave shall be left here for reference, in case the above is not happy, Jan.


    So, for my machine, it seems that every startup script solution I have tried does not resize the text on the screen, on startup. The only solution that has worked for me has been taken from comment #17 at https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1892440 and involves downgrading the libmutter package to the state prior to the upgrade. The commands are as follows:

    sudo apt install libmutter-6-0=3.36.1-3ubuntu3 gir1.2-mutter-6=3.36.1-3ubuntu3 sudo apt-mark hold libmutter-6-0

    The first command reverts the package and the second command stops subsequent update events from updating the package. The second command is optional, but it means that you will manually either have to unselect this update or re-run the first command untill the problem is fixed with the package.
