From 2bc892cf56acbce5d76f3a0c50908b44f8dc49a6 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Tue, 1 Jan 2019 22:28:47 +0100 Subject: libgfxinit: Add options to limit framebuffer size Add maximum width and height options and set the default to 2560x1600 (WQXGA). The framebuffer will be scaled up to the displays' native resolutions. So this should help with tiny fonts on high-DPI displays. For laptops, reasonable defaults can be set at the mainboard level.
