evdevtouch: Enable touch in multi-screen eglfs environments
Parse the touchDevice property from the KMS/DRM config file. When all outputs have an explicitly specified index in the virtual desktop, we can set up a mapping between the device node and the screen index. It is somewhat fragile (device nodes may change, requires explicit virtualIndex properties for all outputs, etc.) but better than nothing. For example, having the screen on DisplayPort as primary and the touchscreen on HDMI as the secondary screen breaks by default because touching the second screen generates touch (and synthesized mouse) events for the first screen. Assuming the touchscreen is /dev/input/event5, the issue can now be fixed by setting QT_QPA_EGLFS_KMS_CONFIG with a configuration like the following: { "device": "drm-nvdc", "outputs": [ { "name": "HDMI1", "touchDevice": "/dev/input/event5", "virtualIndex": 1 }, { "name": "DP1", "virtualIndex": 0 } ] } Task-number: QTBUG-54151 Change-Id: If97fa18a65599ccfe64ce408ea43086ec3863682 Reviewed-by: Andy Nichols <>
