LibreOffice Version: 6.1.4.2 Build ID: 1:6.1.4-0ubuntu0.18.10.1~lo1CPU threads: 4; OS: Linux 4.18; UI render: GL; VCL: gtk3; Locale: en-US (en_IL.UTF-8); Calc: group threaded

I used to have great OpenGL transitions in impress, but since I upgraded to OOo 3.2 hardware acceleration does not work anymore. I cannot find any openoffice.org-ogltrans package for Ubuntu Karmic that works with OOo 3.2 and the option 'Use Hardware Acceleration' in OOo is greyed out. Upgrading is a little trickier though. Annoyingly, unless you have the very recent LibreOffice 3.4.5, you can't upgrade to LibreOffice 3.5: you have to uninstall the version you have and install.

Safe mode is a mode where LibreOffice temporarily starts with a fresh user profile and disables hardware acceleration. It helps to restore a non-working LibreOffice instance.

What can I do in safe mode?

Once in safe mode, you will be shown a dialog offering three user profile restoration options

Continue in Safe Mode

This option will let you work with LibreOffice as you are used to, but using a temporary user profile. It also means that all configuration changes made to the temporary user profile will be lost after restart.

Restart in Normal Mode

Choosing Restart in Normal Mode will discard all changes, terminate safe mode and start LibreOffice again in normal mode. Use this option if you got here by accident.

Apply Changes and Restart

The dialog offers multiple changes to the user profile that can be made to help restoring LibreOffice to working state. They get more radical from top down so you should try them successively one after another. Choosing this option applies selected changes

Restore from backup

LibreOffice keeps backups of previous configurations and activated extensions. Use this option to return to the previous state if your problems are likely to be caused by recent changes to configuration or extensions.

Configure

You can disable all extensions installed by the user. You can also disable hardware acceleration. Activate this option if you experience startup crashes or visual glitches, they are often related to hardware acceleration.

Uninstall extensions

Libreoffice Use Hardware Acceleration

Sometimes LibreOffice cannot be started due to extensions blocking or crashing. This option allows you to disable all extensions installed by the user as well as shared and bundled extensions. Uninstalling shared and bundled extensions should be used with caution. It will only work if you have the necessary system access rights.

Reset to factory settings

If all else fails, you can reset your user profile to the factory default. The first option Reset settings and user customizations resets all configuration and UI changes, but keeps things like your personal dictionary, templates etc. The second option will reset your entire profile to the state when you first installed LibreOffice.
