Contents
1 WiFi Connection
1.1 Gui
Click on the icon on the top right in the FriendlyDesktop's main window, select your wanted WiFi hotspot and proceed with prompts
1.2 Console
Please visit: Use NetworkManager to configure network settings
2 Test OpenGL ES
You can test it by clicking on the Terminator icon to start a commandline utility in the System Tools and run the following commands:
glmark2-es2
3 HDMI/DP LCD Resolution
Open the system's menu and go to Perferences -> Monitor Settings to customize your settings.
Recommended resolution: 1920x1080@60Hz
4 Adjust HDMI overscan
Open the command line terminal and enter the command to operate, Note:
1) You need to login to the desktop;
2) If you are using ssh terminal, please use the same username as the desktop login. The default is pi. You cannot use the root user. you also need to assign the DISPLAY variable:
export DISPLAY=:0.0
4.1 Query which resolutions the display supports
xrandr -q4.2 Set resolution
For example set to 1920X1080@60Hz:
xrandr --output HDMI-1 --mode 1920x1080 --refresh 60
4.3 Adjust the HDMI overscan
For example, the transformation scaling horizontal coordinates by 0.8, vertical coordinates by 1.04 and moving the screen by 35 pixels right and 19 pixels down:
xrandr --output HDMI-1 --transform 0.80,0,-35,0,1.04,-19,0,0,1
4.4 Automatic adjustment at boot
Edit ~/.config/autostart/lxrandr-autostart.desktop，Write the full xrandr command to the key at the beginning of "Exec= as shown below：
[Desktop Entry] Type=Application Name=LXRandR autostart Comment=Start xrandr with settings done in LXRandR Exec=sh -c 'xrandr --output HDMI-1 --mode 1920x1080 --refresh 50 --transform 1.04,0,-35,0,1.05,-30,0,0,1' OnlyShowIn=LXDE
