i rencently installed Volumio on my RPI 3 with attached 10.1 inch Waveshare touchscreen. The installation worked fine, configuration via a second pc and network worked flawless. Now I was trying to install the touchscreen input plugin for which the installation worked also fine without errors. I activated the plugin but all I got now is a grey screen with a mouse pointer (which I can indeed move by touch input). No Volumio webinterface is visible. After looking in the menu of my Touchscreen I saw that it is displaying a resolution of 1920x1200x60Hz which seems to be wrong since it supports natively only 1024x600. I configured this properly in /boot/config.txt:
hdmi_cvt 1024 600 60 6 0 0 0
but I guess volumio is still setting a wrong resolution for the XServer? Is there any chance to correct this? Any help is appreciated!
