Public bug reported: == Justification == After bug 1819881 - [CONFIG] please enable highdpi font FONT_TER16x32, our kernels now support TER16x32 font for high resolution screen.
With Takashi's patch: dfd19a50 (fonts: Prefer a bigger font for high resolution screens) The framebuffer can now decide which font to use base on the screen resolution. It will be great to have this feature in older kernels as well. == Fixes == * aa1d19f1 (fonts: Fix coding style) * dfd19a50 (fonts: Prefer a bigger font for high resolution screens) First patch just changes the coding style, no actual changes were made. The second patch added an extra check to see if we can use highDPI font. These two patches can be cherry-picked into X/B/D For Eoan and onward, they already have these patches. == Test == Test kernels can be found here: https://people.canonical.com/~phlin/kernel/lp-1851623-fb-font-detect/ Patch tested on a Dell UHD laptop and it works as expected, the font displayed in the early boot stage has been set to a more readable one. == Regression Potential == Low, this only affects the frame buffer, changing the way to decide which font to use. ** Affects: linux (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: linux (Ubuntu Xenial) Importance: Undecided Assignee: Po-Hsu Lin (cypressyew) Status: In Progress ** Affects: linux (Ubuntu Bionic) Importance: Undecided Assignee: Po-Hsu Lin (cypressyew) Status: In Progress ** Affects: linux (Ubuntu Disco) Importance: Undecided Assignee: Po-Hsu Lin (cypressyew) Status: In Progress ** Affects: linux (Ubuntu Eoan) Importance: Undecided Status: Fix Released ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Fix Released ** Tags: bionic disco ** Also affects: linux (Ubuntu Disco) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Disco) Assignee: (unassigned) => Po-Hsu Lin (cypressyew) ** Changed in: linux (Ubuntu Disco) Status: New => Incomplete ** Changed in: linux (Ubuntu Disco) Status: Incomplete => In Progress ** Also affects: linux (Ubuntu Eoan) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Eoan) Status: New => Fix Released ** Tags added: disco ** Changed in: linux (Ubuntu Focal) Status: New => Fix Released ** Also affects: linux (Ubuntu Bionic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Bionic) Status: New => In Progress ** Changed in: linux (Ubuntu Bionic) Assignee: (unassigned) => Po-Hsu Lin (cypressyew) ** Tags added: bionic ** Also affects: linux (Ubuntu Xenial) Importance: Undecided Status: New ** Description changed: == Justification == After bug 1819881 - [CONFIG] please enable highdpi font FONT_TER16x32, our kernels now support TER16x32 font for high resolution screen.
