Hi All,
I'm facing a major issue as I'm not able to display x11 in full screen when connecting a FullHD (1920x1080) display panel on the HDMI port off the AVNET SmartEdge IIOT Gateway.
I'm using the latest runtime image from avnet generated on 2020 March 26 (from here).
I have run only those commands, to install X11 server and chromium.
sudo apt-mark hold raspberrypi-bootloader
sudo apt-mark hold raspberrypi-kernel
sudo apt-mark hold raspberrypi-sys-mods
# Get latest updates
sudo apt update
sudo apt upgrade -y
sudo apt dist-upgrade -y
apt-get remove -y --purge scratch squeak-plugins-scratch squeak-vm python-minecraftpi minecraft-pi sonic-pi oracle-java8-jdk bluej greenfoot libreoffice-common libreoffice-core freepats nodejs
apt-get autoremove -y
# install minimal set for x11 and chromium
apt-get --assume-yes install --no-install-recommends xserver-xorg x11-xserver-utils xinit openbox
apt-get --assume-yes install --no-install-recommends raspberrypi-ui-mods
apt-get --assume-yes install --no-install-recommends lightdm
apt-get --assume-yes install --no-install-recommends chromium-browser
I have set the screen resolution in the config.txt with :
hdmi_group=2
hdmi_mode=82
The display panel is reporting the right resolution, but the content (Xorg session) is not full screen.
The fbset command reports a strange resolution of 1824x984 instead of 1920x1080. So I have modified the /etc/fb.modes file and added :
mode "1920x1080-60"
# D: 148.500 MHz, H: 67.500 kHz, V: 60.000 Hz
geometry 1920 1080 1920 1080 32
timings 6734 148 88 36 4 44 5
hsync high
vsync high
accel true
rgba 8/0,8/8,8/16,8/24
endmode
But this does not help. So does someone have been able to run content in full screen on that platform ?
If yes, then what is the magic configuration !
