Re: Can't open display issue from CMD
OK I figured out the issue. Inside .bashrc (in the Linux remote machine), I was executing xrdb every time I was logging in, but I only meant it to execute it when requesting xterm. So, I included the following lines in .bashrc, and everything works. Thank you berndbausch! You were spot on! I didn't realize that xrdb was the cause of my issue, and I solved the problem as you suggested. if [[ -n $DISPLAY ]] then /usr/bin/xrdb -load ~/.Xdefaults fi On Sat, Jan 16, 2021 at 4:23 PM Hans-Bernhard Bröker wrote: > Am 16.01.2021 um 05:40 schrieb Marco Atzeri via Cygwin: > > > > > It seems the remote machine is expecting to run a X interface > > by default. > > Or could it be that the local machine has ssh X11 forwarding turned on > (for this remote machine)?

Or could it be that the local machine has ssh X11 forwarding turned on (for this remote machine)? Turning it off explicitly (-x flag) would turn it off, so if that changes the outcome, you know what happened. Running ssh in -v (verbose) may also help with telling what's going on. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

please reply to the mailing list On 16.01.2021 06:36, Sal Bellofiore wrote: Hi Marco, Thanks for the prompt response. The reason why I don't get asked for a password is because I have setup the RSA public key, and that works fine. When you say to check the remote scripts, what scripts are you referring to? I am not running any remote (Linux) scripts, I am only sending commands like pwd, ls -la, etc. Thanks Sal as also Achim reported the login scripts on the Linux server. https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html#Bash-Startup-Files When you open a remote shell, it runs its login script: "When Bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable" -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

You need to sanitize your login scripts on the Linux machine to only run X11 commands when it actually is available, for instance by conditionalizing on the presence of the DISPLAY environment variable.
