If you work on older Laptops and you use a Console only System Setup like on Debian there is a Bug on systemd and the console-setup package since years. After reboot all Font Settings seems gone. But the Settings are not real gone, cause systemd does not pull the settings on boot!
How to fix?
edit the crontab of root by
sudo su -
insert the /bin/setupcon command on „@reboot“ means on every boot!
@reboot /bin/setupcon > /dev/null 2>&1
save and exit, reboot now
now the PC should echo big Fonts for old eyes „Terminus 20×12 Frambuffermode“
If you use Ubuntu on your Systems, you perhaps read last weeks about a new Release Version.
I am often asked, must i upgrade now?
My answere at first is not really, cause the new Versions are not cleaned up by all bugs and the User or Admin must recheck against the new advantages of the new Releases for production usage. I prefer to wait 3 Month after a Release by Ubuntu is published. But if you setup a very new Hardware your are often forced to take the LAST Release Version, cause it supports newest Hardware Chips by the latest Kernel (for example Laptop mixed Chips Wifi/Bluetooth/USB3.0).
Remark: You should read the „release notes“ of the Versions, cause this can prevent you from running into trouble or „black screens“. DONT forget to Backup the old OS if you try to start the Upgrade. Fresh Setup’s are often smaller and more free of Bugs as „upgraded Systems“! Cause sometimes the old Configs are not all updated or replaced! (User-Homes). New Releases can allocate MORE Disk Space and offer new Call Home Sniffing Tools, RECHECK open Ports, running Processes and Privacy Settings!
On Companies you must always setup a „Lab PC“ for Testing the new Releases before rolling out the OS.

If you use Ubuntu Desktop 16.10 you will run sometimes into freezes of the Desktop with a Default Setup.
Background: Theres a known Bug of the Deja-Dup Backup Service which is started by Cron. The Service take 100% Ram and 100% CPU usage. This did my PC with 16GB Ram too! Only HARD RESET helps to get back Control!
Purge the deja-dup service with:
$sudo apt purge deja-dup
Use instead the „rsync“ tool by command line with users crontab to Backup your User Homes to external or 2nd. Disk.
