What does this WebKit problem indicate? How do I fix it on Ubuntu 22.04.3 LTS?

  • 772

I'm having a webkit issue on Ubuntu 22.04.3 LTS.

I get the following errors when running a Photino app (dotnet dev framework which implements webkit).

KMS: DRM_IOCTL_MODE_CREATE_DUMB failed: Permission denied
Failed to create GBM buffer of size 600x400: Permission denied

Failed to create EGL images for DMABufs with file descriptors -1, -1 and -1

I searched and found Ubuntu official docs about WebKit.

From there I tried the test and I see the following results (anything less than 100 indicates a problem).

webkit test & error

The docs mention that you should have a 100, but it doesn't mention:

  1. What a 97 means
  2. Any extra docs to check and see what a less-than 100 means
  3. any indication of anything else

Does anyone know what that means or how to get more information?

How can I determine which version of WebKit I'm running?

    I'm still having this issue, but I've discovered a few things:

    1. The Version of WebKit I'm running

    Running the following command helped me discover which version of webkit is installed and running:

    $ apt list --installed | grep -i "webkit"

    I see the following after running that:

    libwebkit2gtk-4.0-37/jammy-updates,jammy-security,now 2.42.3-0ubuntu0.22.04.1 amd64 [installed] libwebkit2gtk-4.1-0/jammy-updates,jammy-security,now 2.42.3-0ubuntu0.22.04.1 amd64 [installed]

    I then discovered there is a bug in the version that is running on ubuntu 22.04.3 LTS / Gnome.

    There are details about it here.

    There is also a bug filed for it in bugzilla here.

    However, I cannot seem to fix the issue on my machine since it is going to require that the OS and/or Gnome update to the latest fix.

    What I Tried

    Yesterday, I tried removing the older version of webkitgtk and I lost my entire desktop. Luckily I was able to follow the instructions here to get my desktop going again.

    Updated NVidia Driver: Problem Solved

    I updated to a newer version of the nvidia driver and the problem was resolved.
