I have a Dell Inspiron XPS 15 7559 Laptop which has very high resolution 3840x2160 graphics for it's dual nVidia/Intel Optimus graphics, and so by default the characters on the boot screen are very very small and difficult to read. Win/10 would boot just fine, but living with it is another thing, and that's why I've installed Linux and Grub. It was tricky to get Linux to load with a dual boot to Win/10 due to the EFI setup, as well, but Debian 9.0 to both runs well and install GRUB 2, and it is controlling the boot to Debian, other linux distros, and Win/10, but I would really like to make the boot screen readable without a magnifier if I could. I have tried editing /etc/default/grub to try various combinations of parameters to try to change the font or video mode but none seem to have any effect, and the best result I get is an error before the boot menu. I can tell my changes are taking effect after I run update-grub and reboot because I have changed it to play an unusual tune at boot. I ran the videoinfo command from the grub command prompt to list the video modes available and it says 800x600x32 is valid. I tried creating a large unicode font, but it didn't do anythingI tried changing to 800x600x32 resolution, but it didn't do anythingI tried changing to auto resolution, but it won't accept that when I try to run update-grub Can someone suggest a way to make the characters on the screen larger and more readable, please? Maybe I'm doing something wrong? Any help would be appreciated. If you could suggest things I could try or where to find and example that might work, that would be great.
