GRUB Screen Size in a Thinkpad T580
Not quite the curious incident of the dog in the nighttime, but after installing Slackware 15.0 in the Thinkpad T580, the GRUB boot menu filled the entire screen — with unfriendly tiny fonts. The screen resolution is 1920x1080.
Fiddling with different GRUB resolutions proved futile.
Reading around the web indicated the problem might be related to the UEFI BIOS. Some people recommended dropping into the GRUB command line and running the
videoinfo command. No results.
The fix was ensuring some
pf2fonts were installed in
/boot/grub/fonts. The default font is
dejavusansmono.pf2, which can be found in
After copying the fonts the GRUB font sizes were larger, the menu size was smaller, and the
videoinfo command succeeded.
