This post describes how to adapt the size of the Grub splash screen and the virtual terminal on Debian.
In the following, I will set both to the size of 1280 x 1024 pixels. This may not suit your installation. To be sure, install the tool hwinfo and check the available configurations:
|
1 2 |
sudo apt-get install hwinfo sudo hwinfo --framebuffer |
Grub splash scren
Open /etc/default/grub (as root) and add/modify the following lines:
|
1 2 3 |
# in file /etc/default/grub GRUB_GFXMODE=1280x1024 GRUB_GFXPAYLOAD=1280x1024 |
Afterwards, update the grub configuration and reboot:
|
1 2 |
sudo update-grub2 sudo reboot |
Now, the Grub splash screen appears larger, but the virtual console of Debian is still quite tiny.

For increasing the size of Debian’s virtual terminal, open /etc/default/grub, again and add the following line:
|
1 2 |
# in file /etc/default/grub GRUB_GFXPAYLOAD_LINUX=1280x1024x16 |
