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 share your Systems and you want to disable USB Drive connects there is a small solution. By default the gvfs Service handle all automounts and drive scans. On old Linux Systems you could purge the complete gvfsd “Backend” but Ubuntu-Desktop forces some pakets to the default Desktop Package! If you purge it the working Desktop can be destroyed!
It’s easier to disable the “USB Drivers” called Modules from load on Start! Cause Rules are “Software” and can FAIL unknown!!
Howto? Edit the /etc/modprobe.d/blacklist.conf and add:
Update initramfs (Kernel Image)
update-initramfs -u -k all
Now try to plugin USB Sticks , they should now be ignored!
To enable USB Drives temporaily do:
$sudo modprobe uas
Now the USB Stick should be able to mount for root!
Advantage? No gvfs, org.freedesktop rules or package deps are touched!
Remark: On Laptops DISABLE all USB Devices for Security Reasons! There should now “Fake Keyboard” or “Fake Mouse” be able to enter the Systems!!! (USB Kill Sticks)
