I have a cronjob that didn't work this morning. The line in crontab -e looks like this:

20 9 * * 1-5 export DISPLAY=:0 && /bin/bash /opt/ibc/twsstart.sh

I couldn't find any errors in /var/log/syslog, but when I try to run that command in my terminal, I get the following error:

taylor@mean-machine:~$ export DISPLAY=:0 && /bin/bash /opt/ibc/twsstart.sh
taylor@mean-machine:~$ xterm: Xt error: Can't open display: :0

Would this have anything to do with me trying to install Nvidia drivers and Cuda last night? That installation gave me trouble and I remember fiddling a lot with adding and removing libraries. I think I remember seeing something about xserver in there.

  • Might want to see: askubuntu.com/a/1334403/231142 as depending on what DM you are using and how you login can determine if DISPLAY is :0 or :1.

Reset to default

Per @Terrance's suggestion, somewhere in me messing with things, DISPLAY got changed to :1 from :0.
