[CONFIG] please enable highdpi font FONT_TER16x32

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1819881

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

Patch available in Disco.
Porting to T/X/B/C

Oops, mis-understand this.

Patch available in Disco, but the config needs to be enabled.

Test kernel for Disco with this config enabled:
  http://people.canonical.com/~phlin/kernel/lp-1819881-font/D/

I will just patch this for D, for T/X/B/C, it looks like the FONT_TER16x32 support (ac8b6f14) can be cherry-picked as well, please let me know if we want this for older releases.

Found a UHQ device for the test, it seems that even with
  CONFIG_FONT_TER16x32=y

and set it to y for all the arches in annotations, this is still not working.

Will keep checking what's missing here.

BTW, the way how I check this is to lookup FONTS in the config file:

$ grep FONT /boot/config-5.0.0.9-generic
CONFIG_FONT_SUPPORT=y
# CONFIG_FONTS is not set
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y

System was booted with kernel parameter fbcon=font:TER16x32

I am in ecstasy! this is so good! OMG! My eyes! I love this!

After installing your kernel, one needs to enable the font in console-setup too:

$ cat /etc/default/console-setup | grep '^FONT'
FONTFACE="TER"
FONTSIZE="16x32"

Then i did update-initramfs, and rebooted, and omg how nice my tty is now!

If you can, please cherrypick this patch into all the GA kernels as far back as possible, if it like applies cleanly without too much trouble.

Later, we will need to work on enabling console-setup (or maybe kernel?!) to autodetect and autopick TER 16x32.

Thanks for sharing the tips, it's a bit hard to find these steps on the Internet, perhaps because these is a new feature.

Will try to bring this to other kernels.

Hi Dimitri,

While trying to verify this on other kernels, I found that you can even enable this TER 16x32 font without this patch.

Just change what you mentioned in comment#7
FONTFACE="TER"
FONTSIZE="16x32"

Run "update-initramfs -u" and reboot (or one can use "dpkg-reconfigure console-setup" to choose with Terminus 16x32). I think maybe this is not using the kernel compiled-in fonts.
If that's the case, we need another way to verify this fix.

Can you confirm this fact?
Thanks

Indeed, i booted the stock kernel with my new console-setup settings... and i get readable ttys still.

And the config for your kernel did not appear to list 16x32 there either.

Can you please share the source for the kernel you have built?

Also I wonder where the TER 16x32 font is coming from, and how can we make it like the default on the Ubuntu Desktop.

Thanks for the feedback.

This is the old patch that I used to compile the test kernel in #4:
https://pastebin.ubuntu.com/p/dkGBkd2R85/

I think I have found the cause, the compiled-in option was not set.

If you run "make menuconfig" against a clean source to enable TER16x32 (Library routines >> Select compiled-in fonts, the interactive menu will tell you that you will need this. Although you can still unselect this compiled-in fonts after enabling TER16x32)

A v2 has been built successfully on the Disco test machine at hand:
u@ubuntu:~$ cat /boot/config-5.0.0-9-generic | grep FONT
CONFIG_FONT_SUPPORT=y
CONFIG_FONTS=y
CONFIG_FONT_8x8=y
CONFIG_FONT_8x16=y
# CONFIG_FONT_6x11 is not set
# CONFIG_FONT_7x14 is not set
# CONFIG_FONT_PEARL_8x8 is not set
CONFIG_FONT_ACORN_8x8=y
# CONFIG_FONT_MINI_4x6 is not set
CONFIG_FONT_6x10=y
# CONFIG_FONT_10x18 is not set
# CONFIG_FONT_SUN8x16 is not set
# CONFIG_FONT_SUN12x22 is not set
CONFIG_FONT_TER16x32=y

Will try again on our build server.

Attachment is a screencap before and after the patch, sorry for the motion-blur.
You can notice that the font is larger after the patch.

The verification of the Stable Release Update for linux-azure has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

For those who would like to benefit from this fix, please:
1. For fonts in early boot stage:
  Add "fbcon=font:TER16x32" to the GRUB_CMDLINE_LINUX in
  /etc/default/grub and run "sudo update-grub" and reboot
2. For fonts after boot (not related to this fix, but you might
need this as well):
  Run "sudo dpkg-reconfigure console-setup" to choose a bigger
  font. (if you need a non-interactive solution, please check
