Boot menu uses a tiny font (GRUB menu).
|
|
||||||
|
You can add this in your auto-start application list:
|
||||||
Best way to address this would be to have GRUB automatically select the right font, but GRUB is kept small on purpose, or to install a larger GRUB font when installing Ubuntu.
|
|
||||||
|
~~~
|
||||||
Workaround: let the default GRUB terminal driver, gfxterm, switch to a supported mode such as 1600x1200 (NB to list video modes, disable secure mode in the BIOS and run the videoinfo command in the GRUB shell accessed by pressing "c" from the GRUB menu):

/usr/bin/xrdb -merge /home/nomad/.Xresources

Splash screen uses too small logo and somewhat too small fonts (Plymouth).

Plymouth has logic to detect the proper scaling to apply, but it's still too small; workaround by forcing the scale on the kernel cmdline:
|
GRUB_GFXMODE=1280x1024
|
||||||
|
~~~
|
||||||
Add to GRUB_CMDLINE_LINUX in /etc/default/grub.

Console terminal uses too small fonts.

Note that the package shipping the Ubuntu Monospace font for the terminal, fonts-ubuntu-console, is not installed by default and only ships 8x16 fonts.

Change the font by running :

update-grub

dpkg-reconfigure console-setup

|

select a font face that supports a larger font size, for instance the Terminus font, and select a large font size such as 16x32; you need to reboot for the new font to be set.
