[gentoo-user] thunderbird small fonts on hidpi

[Valmor de Almeida]

Hello,
Does anyone know how to fix Thunderbird UI fonts on a HiDPI
Gentoo/OpenBox system with no desktop?
A similar problem exists with Firefox but it can be fixed using a CSS
file (userChrome.css). However I can't get Thunderbird to work using a
similar fix. The UI fonts are so small that the app is useless.
Thanks,

Hi Valmor, I'd think TB also uses CSS to modify the look of the GUI - but I 
don't have it installed on this PC to check its file structure.  This post 
suggests so:

I also found this Addon which claims to do just what you're after, but I have 
not tried it out:

Thanks Michael.
The CSS info is more detailed than what I had. Initially it did not
help but I noticed the cyan color appeared on the menu bar. Hence I
increased font sizes to 25 and 30 and it made a difference.
However various places still have the small fonts; e.g. dialog windows
for say, configuring an email account, etc. This will require some
fine tuning...
Later,

Do you have an ~/.Xresources file? It can have something like:

Xft.dpi: 144

Which is also passed to Xorg for me: -dpi 144 (Plasma does this by
modifying SDDM service file(s) to systemd).

No I don't have it. I thought the line

xrandr --dpi 192 &
or
xrandr --output eDP-1 --mode "3840x2160" --scale "0.75x0.75"

in ~/.xinitrc was sufficient to fix Firefox; it doesn't fix TB.

I just added
Xft.dpi: 192
to ~/.Xresources and not only TB works but LibreOffice works too.
Of course all of this defies the purpose of having an HiDPI laptop but
it is either that or no use at all.

Thank you Andrew.

For Qt apps you might want these environment variables in .xinitrc:

QT_SCREEN_SCALE_FACTORS=DVI-I-0=1.5;DVI-I-1=1.5;HDMI-0=1.5;DP-0=1.5;DP-1=1.5;DP-2=1.5;DP-3=1.5;DP-4=1.5;DP-5=1.5;

(These device names are the same as what xrandr shows.)

QT_AUTO_SCREEN_SCALE_FACTOR=0

Currently I have an issue where opening Qt apps from certain contexts results in resetting the DPI scale to 2 instead of 1.5. Primarily this happens when Chrome launches a Qt-based viewer such as Kate, and sometimes it happens from Konsole. Have yet to file bugs.

Thank you. Got those in too. Helpful when I start looking at other X apps.
