QXcbConnection: Failed to initialize XRandr
Qt: XKEYBOARD extension not present on the X server.
Qt: Could not determine keyboard configuration data from X server, will use hard-coded keymap configuration.
Qt: Failed to compile a keymap!
Current XKB configuration data search paths are:
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ':' as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see http://cgit.freedesktop.org/xkeyboard-config/ .
