If this server is no longer running, remove /tmp/.X1019-lockĪ sample shell script is attached, which demonstrates starting and stopping Xvfb for command-line execution. Server is already active for display 1019 If another application is using the same DISPLAY value, a useful message is displayed: To stop Xvfb cleanly, use the kill command to send the SIGTERM signal. Test execution completed in 113.448 seconds. It provides a fake display buffer for graphical programs to write to, thus allowing any program to run headlessly. Parameters accepted, starting the test run. Xvfb is a virtual display framebuffer for X - the display system used by Linux. During execution, the same font warning messages are displayed: You can now run RPT/RTW from the command line. On SUSE Linux Enterprise 10 or Red Hat Enterprise Linux 4, you might see the following messages:Ĭould not init font path element /usr/X11R6/lib/X11/fonts/TTF/, removing from list!Ĭould not init font path element /usr/X11R6/lib/X11/fonts/CID/, removing from list! These warning messages can be ignored.įreeFontPath: FPE 'unix/:7100' refcount is 2, should be 1 fixing. This same warning is reported when RPT/RTW accesses the X Server. A warning might be displayed when you run the xlsclients utility. The xlsclients utility lists client applications that are running on a display. RPT/RTW does not require specific values for the display number, screen, resolution, or depth. The values for display number, screen, resolution and depth are arbitrary. On any of the supported distributions of Linux, as a non-root user, launch Xvfb: See the documentation for your Linux distribution to find out how to install and use Xvfb. The Xvfb package is bundled with most Linux distributions. Use the X virtual framebuffer (Xvfb) to provide the necessary components to run tests from the command line on Linux on computers with no physical display device.
