Linux Kernel

For those who want to test the latest Linux kernels, Ukuu (Ubuntu Kernel Upgrade Utility) offers a simple interface with list of the “mainline” Kernels and allow user to one-click download and install a selected kernel release.

The mainline kernels are provided by Ubuntu Kernel Team for testing and debugging purposes. They are not supported and are not appropriate for production use. You should only install these if they may fix a critical problem you’re having with the current kernel. Read more about mainline kernels.

  • Flow on Paint Dynamics editor dialog: the ‘y’ axis is indicating ‘Rate’ instead ‘Flow’
  • Vertical ruler shows artifacts if the status bar isn’t showing
  • Tablet stylus misbehaves when crossing the edge of a dock in multi-window-mode
  • Disable the new “automatic window tabbing” feature introduced on mac OS Sierra
  • Improve the visiblity of slider handles with dark themes
  • Make it harder to switch to renaming if selecting already selected items in resource lists
