sudo takes a long time (when network having issues) #
Reason: distros should have added new host name to /etc/hosts, if the name is changed/added during installation ref.
echo -n '127.0.0.1 ' >> /etc/hosts && cat /proc/sys/kernel/hostname >> /etc/hosts

update-grub && reboot.
- If the oficial solution does not work, try edit
/etc/grub.d/10_linux, comment out the usage of
if ... then), and run
- Although renaming defination of
function gfxmodedirectly is easier and can work, (can be done automatically by simple
sed/py regular expression), this will raise an error and pause for 3s during boot.
