The new boot option allows changing the display console mode to some new display resolution. Usage: in systemd-boot configuration file loader/loader.conf add one of: console-mode <number> console-mode auto console-mode max console-mode keep Where number can be: 1) 0: UEFI standard 80x25 mode 2) 1: 80x50 mode, if supported by device 3) 2 or greater: some non-standard device mode, if supported When using the auto mode, systemd-boot will try to find a reasonable mode automatically using some heuristic. Current implementation tries to switch console mode to mode 2 if it exists, mode 1 if it exists, else mode 0. Mode 2 is the first non standard mode provided by the firmware developer and it's assumed to be a reasonable mode. The max mode adds support for switching to the highest numbered console mode, whatever mode that would be in the system. The maximum mode being the last one implemented by the firmware provider should be a reasonable mode. The keep mode is the default and is only included for completeness. With this parameter, the user explicitly states and can be assured that systemd-boot will not change console mode. Note: patch includes a workaround for mode 1, that may not exist in EDK2 OVFM and results in a buggy text mode when requested.
