Screen output on node_manager not working #117

Closed weixuanzhang closed 4 years ago

weixuanzhang commented 4 years ago

Hi, I recently updated the node_manager, I am not able to output node to the terminal anymore. A snippet from /var/log/dpkg.log 2019-12-02 17:14:24 upgrade ros-kinetic-node-manager-fkie:amd64 0.8.11-0xenial-20190227-103017-0800 0.8.12-0xenial-20191029-002604+0000

When I click the output button on node_manager, the terminal that runs node_manager outputs: [INFO] [1576578161.392919]: Open screen terminal: /usr/bin/x-terminal-emulator -T "SCREEN /omav/omav_allocation_node on weixuan-blade" -e /usr/bin/screen -x 6913._omav_omav_allocation_node

But no external screen is spawn. My system setup: System: Ubuntu 16.04, ROS: kinetic Terminal: terminator 1.91

When I run "sudo update-alternatives --config x-terminal-emulator" I choose

Any help much appreciated! Thanks!

Hi,

can you please check two things (in separate terminal):

  1. Is the screen running: screen -ls
  2. Does screen open if you run: /usr/bin/x-terminal-emulator -T "SCREEN /omav/omav_allocation_node on weixuan-blade" -e /usr/bin/screen -x 6913._omav_omav_allocation_node <-- This is the line which node_manager prints and executes to open screen terminal

Thank you very much for your quick response!

  1. When I run screen -ls: There are screens on: 7369._omav_spawn_omav (17.12.2019 11:22:36) (Detached) 7081._omav_omav_controller_node (17.12.2019 11:22:36) (Detached) 6913._omav_omav_allocation_node (17.12.2019 11:22:35) (Detached) 6832._omav_local_planner (17.12.2019 11:22:35) (Detached) 6727._omav_full_pose_waypoint_node (17.12.2019 11:22:35) (Detached) 3654._roscore--11311 (17.12.2019 11:14:50) (Detached) They are the running nodes in the node manager. 6 Sockets in /var/run/screen/S-weixuan.

2.When I run /usr/bin/x-terminal-emulator -T "SCREEN /omav/omav_allocation_node on weixuan-blade" -e /usr/bin/screen -x 6913._omav_omav_allocation_node I get terminator: error: Additional unexpected arguments found: ['/omav/omav_allocation_node', 'on', 'weixuan-blade']

I also upgraded the terminator. Could it be that it does not recognize this command anymore?

Thanks!

I tested it with terminator v1.91 on Ubuntu 18.04 and the command line works.

I think it is something with selected alternatives for x-terminal-emulator. Can you change it to terminator?

weixuanzhang commented 4 years ago

Thank you very much for your input! Indeed it has something to do with the selected alternatives for x-terminal-emulator. The catch is that I installed the terminator 1.91 from ppa:gnome-terminator/nightly-gtk3. When setting default terminal, I have to switch from /usr/bin/terminator.wrapper to /usr/bin/gnome-terminal.wrapper. Now it works again.I will close this issue.
