Changing tty Console's Screen Resolution on Ubuntu  

Note: these notes apply to Ubuntu 24.04 LTS.

1. Reboot to get to the GRUB screen.
2. At the GRUB screen, type c to enter the grub > shell.
3. Run videoinfo, and identify the particular screen resolution you would like to use.
   • In this case, say we want to use 2560x1440
4. Reboot into Linux.
5. Edit /etc/default/grub to add / update the following lines
   • GRUB_CMDLINE_LINUX_DEFAULT='quiet nosplash nomodeset'
     • in my case, I appended 'nomodeset'¹ to 'quiet splash' which was already present on this line; ensure the content is inside a single quote).
   • GRUB_GFXPAYLOAD=2560x1440
   • GRUB_GFXPLAYLOAD_LINUX=keep (note: no quotes around ‘keep’ here)
6. Run 'sudo update-grub'
7. Run 'sudo reboot now'
