MATE is a desktop environment forked from the maintained code base of GNOME 2. It is installable on postmarketOS.

Status

It works on most devices with a working display, works fine without hardware acceleration.

After the postmarketOS loading splashscreen you will get a black screen for 20-30 seconds before the desktop appears. This seems due to an issue with marco (MATE window manager):

mate-session[1377]: WARNING: Application 'marco.desktop' failed to register before timeout

Install MATE Desktop

Run pmbootstrap init and choose mate in the interface section. The Alpine repository already contains all the packages for x86_64, armhf and aarch64 architectures. Nothing has to be done to enable it.

After installation, the shell will automatically launch upon boot. If it doesn't, have a look at /etc/profile.d/start_mate.sh script.

For the official MATE instructions, see their website.

Troubleshooting

Check the logs with logread -f | grep x11

Landscape mode

Rotate the screen

You can rotate adding the following configuration file: /etc/X11/xorg.conf.d/00-fbdev-rotate.conf

Section "Device"
  Identifier "LCD"
  Driver "fbdev"
  Option "Rotate" "CW"
EndSection

Rotate the touchscreen

In order to also rotate the touchscreen you need to change the udev rule: /etc/udev/rules.d/90-device-samsung-i9070.rules And add one of the following line:

# 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"

and reboot udev or the device.
