Hello,

I have a laptop on which I have installed Alpine.  So far, seems like a great OS and has the features I need.  I am not using a GUI just command line.  The laptop screen is a 13" 1K (1920x1080) screen.  Alpine recognizes the native resolution and adjust the display to 1K.   However, at this resolution the text is way too small.  How can I adjust the post boot up resolution to something more useful such as 1280x720?   I have searched the internet and discussion boards but have not been successful in a solution that works.   Thanks for any help you can provide.

Best regards,

I didn't try this myself, but AFAIK you have to set the framebuffer resolution
in the bootloader. First, check out the supported resolutions using hwinfo:

```
$ apk add hwinfo
$ hwinfo --framebuffer
```

Then you can set the desired resolution in the bootloader. If you use syslinux,
you achieve that by editing the bootloader configuration (/boot/extlinux.conf):

```
MENU RESOLUTION <width> <height>
```

HEY! there's two behaviour here!

one its made the fonts more bigger at the framebuffer console and other are
made the resolution without space!

1) with max resolution but fonts bigger will consume more because it will
need more RAM for the video buffer and cpu processing, but will be more
controlled
2) with a specific lower resolution (pass MENU RESOLUTION <width> <height>
at extlinux.conf) will run more optimized due less consuption
