I have Raspberry Pi 2B, touchscreen, Raspbian Jessie 2016-05-10 with default LXDE desktop environment, installed matchbox-keyboard.
When I run matchbox-keyboard it works correctly, but Raspbian GUI hangs (I can't open any folder in the file manager and if any folder is opened it also hangs and can't be closed).
After closing matchbox-keyboard there is an error in the terminal:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0" after 5077 requests (5077 known processed) with 0 events remaining.
Also Raspberry doesn't turn off, it hangs after shutdown.
This error appears both with touchscreen and simple LCD monitor.
Tell me please how to fix this error? Or how to restart graphical interface (if it will help)? Are there any analog of matchbox-keyboard?
