X11 / xserver / XWIN gvim problems

GullCode

Case:

WARNING**: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files

Solved by adding NO_AT_BRIDGE=1 before launching gvim ( i.e [user@server]$ NO_AT_BRIDGE=1 gvim myfile.txt) source: https://github.com/NixOS/nixpkgs/issues/16327

Case:

connect /tmp/.X11-unix/X0: Permission denied
E233: cannot open display
Press ENTER or type command to continue

Solved by using correct DISPLAY informations before connecting (DISPLAY=localhost:0.0) source: https://unix.stackexchange.com/a/220234

execve: no such file or directory

GullCode

If one day when using execve you encounter the “no such file or directory” problem, and that the file you tried to launch is really existing and with the good rights, then the problem is coming from the shebang not pointing to a valid interpreter.

In example: #!/bin/ksh and ksh is not installed

New to GDB or in need of good ressources about it ?

Here you go:
https://www.st.com/resource/en/user_manual/usermanual_debugging_with_gdb-user-manual–debugging-with-gdb-for-stm32cubeide-stmicroelectronics.pdf

That manual I stumbled upon while searching for some informations on how to configure gdb is THE thing.

From starting to crashing, each possible good analysis is covered in that manual.

Good reading !
