It looks like as of libinput 1.6.0 the trackpoint and touchpad are recognized separately. Unfortunately, the trackpoint is nearly unusable due to sensitivity issues.
Enabling an external monitor causes trouble because Xorg can only handle one DPI, and right now that's set to work with the hiDPI internal screen.
Activate the external monitor with arandr, if the gui is too large:
xrandr --output eDP-1 --auto --output HDMI-2 --auto --panning 3840x2160+3840+0 --scale 1.5x1.5 --right-of eDP-1

With the intel video driver (bumblebee) the screen dpi is not automatically discovered, so I set it manually (by physically measuring the screen).
$ cat /etc/X11/xorg.conf.d/10-monitor.conf

Restart X, and then check the configuration:
screen #0: dimensions: 3840x2160 pixels (380x210 millimeters) resolution: 257x261 dots per inch
Once this is configured properly several programs (such as Chromium) will automatically begin resizing properly (or at least a little better).
Xft / Xresources
|Status: Holy Grail|
https://keithp.com/~keithp/talks/xtc2001/xft.pdf (page 8, table 3)
Even after making sure X knows what the screen DPI is, a lot of tertiary fonts still render too small. These are things like context menus on terminals, or menus on taskbar icons. Setting the Xft DPI appears to help with most of them.
$ cat ~/.Xresources
XTerm*renderFont: true XTerm*faceName: VeraMono XTerm*faceSize: 10 Xft.dpi: 261 # <-- Corrects font size Xft.autohint: 0 Xft.antialias: true Xft.rgba: rgb Xft.hinting: true Xft.hintstyle: hintslight Xft.lcdfilter: lcddefault
tty / console font
This affects TTY virtual terminal fonts, as well as a few GUI programs (XTerm).
KEYMAP=us FONT=ter-v32n FONT_MAP=8859-1
i3 window manager / i3wm
It looks like i3 properly handles the X server DPI, but you have to set a Pango font.
$ cat ~/.i3/config
[...] # font for window titles. ISO 10646 = Unicode #font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1 # <-- Old font font pango: Ubuntu Mono 10 # <-- HiDPI font [...]
[greeter] [...] xft-dpi=261 [...]
I followed the selected answer on the above link step by step.
Chromium actually works out of the box once the X server DPI is properly configured. But it actually appears to over-compensate in my case, and the UI is uncomfortably large. To fix this, follow the instructions below.
Edit the desktop file to include a parameter that isn't listed in the man page. The '2' in this case can be replaced with whatever real number suites your needs (e.g.
Exec=chromium --force-device-scale-factor=2 %U
|Status: works, but is a kludge|
Install the theme/plugin and it'll warp the window into looking OK.
Worked completely out of the box.
Dunst / Send-Notify
Dunst doesn't automatically respect DPI, but the config file can manually specify a larger font.
[global] #font = Monospace 10 font = Ubuntu Mono 16 [...]
As of version 1.8.0:
Go to File>Preferences>Interface Scale and set it to whatever you want.
|Status: mostly works|
I followed the wiki section step for step. It works well, except that text before the Grub menu (dm-crypt prompt) and early boot (before kms?) is still small. See: https://bbs.archlinux.org/viewtopic.php?id=219426
|Status: works (with Xft configured)|
With Xft (everything just works)
Without Xft (ui elements too small)
Change the font in Preferences>Profiles>General. Other UI elements are not properly resized.
|Status: partially works (in version 0.92)|
Go to Preferences>Interface and set the icons to 'Larger'. Only affects most icons, not all of them.
|Status: works, but looks awful|
The interface just looks bad, with some text resizing appropriately, and some buttons/ui elements not resizing. Also, the largest thumbnail setting is tiny.
Evince / Document Viewer
|Status: works (mostly)|
With the Xft DPI workaround, UI text is properly displayed. Buttons are still too small, but it's survivable.
|Status: almost works|
This icon theme works, but the next time gimp is run, it segfaults until the theme is removed from ~/.gimp-2.8/gimprc
|Status: somewhat works|
Eclipse Neon is touted as supporting hidpi, but it doesn't work on my system.
To fix icons
To fix fonts
Open Window>Preferences and edit the fonts in General>Appearance>Colors and Fonts.
Most UI fonts resize with the User:Ctag#Xft_.2F_Xresources workaround.
|Status: somewhat works|
with the User:Ctag#Xft_.2F_Xresources workaround, text is displayed well in most areas of the UI. Buttons are still too small.
I don't know if this helps, but here's my config:
$ cat ~/.config/fontconfig/fonts.conf
<?xml version="1.0"?> <!DOCTYPE fontconfig SYSTEM "fonts.dtd"> <fontconfig> <match target="pattern"> <edit name="dpi" mode="assign"> <double>261</double> </edit> </match> <match target="font"> <edit mode="assign" name="rgba"> <const>rgb</const> </edit> <edit mode="assign" name="hinting"> <bool>true</bool> </edit> <edit mode="assign" name="hintstyle"> <const>hintslight</const> </edit> <edit mode="assign" name="antialias"> <bool>true</bool> </edit> <edit mode="assign" name="lcdfilter"> <const>lcddefault</const> </edit> </match> </fontconfig>
|Status: not used|
It looks like there's no progress on either Infinality or the bohoomil patches.
Sometimes the sound card cuts out (usually after a suspend/resume cycle) and only a dummy device is listed in the pulseaudio mixer.
Here's one workaround: https://bbs.archlinux.org/viewtopic.php?pid=1201242#p1201242
