I am a software/firmware developer, working in Dresden, Germany. In my free time, I spent some time on developing apps, presenting some interesting findings here in my blog.
Setting console font size on HiDPI screens in Fedora
I recently switched to another laptop which has a HiDPI screen. As usual, the thing is running Fedora (currently in version 25). Especially the KDE desktop was quite easy to configure to be usable; basically, it is a thing of starting System Settings, going to Display and Monitor and using the Scale Display button to bring up a neat configuration dialog which allows you to set a scaling factor for the monitor. For my particular setup, a factor of 2 works quite nice for the UI to be usable.
One open point was the font size in the Linux console as well as in GRUB2. However, some configuration changes later this was fixed as well ;-)
Increasing Font Size of GRUB2
First, I generated a custom font file from one of the TTF fonts installed on my system (in this case from Google Noto):
sudo mkdir /boot/grub2/fonts sudo grub2-mkfont -s 36 -o /boot/grub2/fonts/NotoSansRegular36.pf2 \ /usr/share/fonts/google-noto/NotoSans-Regular.ttf
This font can now be used in
GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="gfxterm"** GRUB_CMDLINE_LINUX="..." GRUB_DISABLE_RECOVERY="true" GRUB_FONT="/boot/grub2/fonts/NotoSansRegular36.pf2"
Basically, I added the
GRUB_FONT entry which points to the font to use. In addition, I had to change the
Note: The remaining entries must remain as they are! Only edit the two variables. Finally, the GRUB configuration can be regenerated. Depending on whether you have EFI or a BIOS, this can be done via:
# BIOS sudo grub2-mkconfig -o /boot/grub2/grub.cfg # EFI: sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Increasing the Console Font Size
To increase the font size for the Linux console (
Ctrl+Alt+F[2-8]), first install the
sudo dnf install terminus-fonts-console
Now, change to a TTY and use the
setfont command to load one of the fonts. You will find them in
/usr/lib/kbd/consolefonts/. For me, the
ter-m32n font works quite nicely:
sudo setfont ter-m32n
To make this font the default console font, edit
/etc/vconsole.conf and adjust the
