DMTCP doesn't support checkpointing of GUI-based applications by default. Please see http://dmtcp.sourceforge.net/FAQ.html#xwindowsSupport for a workaround.
You can also try starting your application under XPRA server, which is supported. Example: # Run the xpra server and an instance of the dbus server under DMTCP $ dmtcp_launch /usr/bin/dbus-launch /usr/bin/xpra --no-daemon --no-mdns --no-pulseaudio start :100 --start-child=xclock # Run the following command from a separate terminal to connect with your application $ xpra attach :100 # Detach from xpra server before checkpointing; re-attach after checkpointing if needed $ dmtcp_command --checkpoint # Try restarting after killing the xpra session $ ./dmtcp_restart_script.sh On Fri, Apr 22, 2016 at 10:11:06PM +0000, Ashutosh Varma wrote: > If an application needs DISPLAY to launch some GUI, it seems that DISPLAY env > from the shell from which dmtcp_launch is invoked is not passed to the > application. > > For e.g.: > > dmtcp_launch xclock > > fails with error: > > Error: Can't open display: > > While xclock directly works on the shell using DISPLAY env set. > > Am I missing something here?
