The BIOS unfortunately does not offer the option to switch from GUI to Simple Text mode, as it did in previous generations of the X13.
Hardware

Brightness control
As of kernel 5.9 use the native brightness controller, use the acpi_backlight=native kernel parameter.
Wireless
The wireless card is sometimes significantly slower than usual after waking up from standby. This might be related to a known issue on the Lenovo forum that Lenovo is currently investigating as of December 2023. Toggling the card with rfkill (or Fn+F8) seems to solve the problem when it occurs.
Another option is to disable power save for the card
# iw dev wlp1s0 set power_save off
A more permanent solution can be found at Power management#Network interfaces - replace on with off.
Firmware
fwupd does support this device.
