Ubuntu 20.04 Change Default Login Screen to Primary Monitor

With a multi-monitor Ubuntu setup, Login screen may not display on the primary monitor as defined under Settings > Screen Display.

In order to make the necessary change in Ubuntu 20.04 LTS, make sure ~/.config/monitors.xml file exists.  If not, go to Settings > Screen Display, make some dummy changes then change back to the desire settings.  For example, adjusting one of screen orientation.  This action would generate montors.xml file.

In the console, execute the following command.

sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config/

This would copy the file into gdm3 configuration folder.

Restart the machine and login screen would display on the primary monitor.

Ubuntu Chinese Input Method

Chinese input is non-existence out-of-box from Ubuntu (and up to 20.04 so far). More work is required to setup Chinese input support. While there are multiple variances out there, Chinese Intelligent Pinyin works best for me.

To install Chinese Intelligent Pinyin, search "ibus-libpinyin" online. Basically, update ibus then install ibus-pibpinyin.

sudo apt-get install -y ibus-libpinyin

Perform a reboot. Note, there is a way to refresh without a reboot but reboot is easier.

Then go to Settings > Language and Region, under Input Sources, click + then Other. Select "Chinese (Intelligent Pinyin)" from the list. Note, it is not "Chinese" in the list as it basically does nothing.

FAT32 Format for Size Over 32GB

FAT32 can search up to 32GB.  In order to format a disk larger than 32GB, it would be exFAT format.

Windows does not have a default utility to perform this task.  Instead, search for guiformat.exe online.  Ridgecrop Consultants Ltd has a good alternative.
