Hildon
![]() Hildon running in QEMU | |
Name | Hildon |
---|---|
Graphics stack | X11 |
Toolkit | GTK+2, WIP: GTK+3 |
In postmarketOS | |
Package | postmarketos-ui-hildon |
Status | Available |
This is the desktop from Maemo, which is a Debian-based distribution, that originally ran on the N900.
We do not have a postmarketos-ui-hildon
yet (but that should be easy to make, look at postmarketos-ui-weston
for reference if you're interested, dear reader).
Installation instructions
In pmbootstrap init
, select hildon
as user interface, then do the installation as usually. When running postmarketOS, it should boot automatically into Hildon now!
Running
hildon-desktop can be run in a horizontal view only. To run programs from the terminal you need to export DISPLAY=:0
. To set it by default edit sudo nano /etc/profile
.
Rotate screen using fbdev driver
In order to rotate the screen using the framebuffer, you need to create this file:
/etc/X11/xorg.conf.d/1-fbdev.conf
Section "Device" Identifier "LCD" Driver "fbdev" Option "Rotate" "CW" EndSection
reference: https://www.x.org/archive//X11R6.8.0/doc/fbdev.4.html
Rotate screen using xrandr
In order to rotate the screen using xrandr, you need to edit a file and put xrandr -o right or xrandr -o left:
sudo nano /etc/postmarketos-ui/xinitrc_hildon.sh
xrandr -o right exec hildon-desktop
Calibrate the touchscreen
After rotating the screen change/add a value in this file:
sudo nano /etc/udev/rules.d/90-android-touch-dev.rules
ENV{ID_INPUT}="1", ENV{ID_INPUT_TOUCHSCREEN}="1", \ # default ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 1 0" # Left - 90 degree clockwise ENV{LIBINPUT_CALIBRATION_MATRIX}="0 -1 1 1 0 0" # 180 degree clockwise ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1" # Right - 270 degree clockwise ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1" # reflect along y axis ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 1 0 0"
Performance issues
Software rendering is slow. A possible fix is in the Software OpenGL article with TinyGLES and similar software.
