Previously when I needed to automate an X app I configured the machine to login automatically, exported the DISPLAY variable in the test script and used wmctrl to detect if an application had a window displayed yet. -- Mel Gorman SUSE Labs -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
