I can reproduce the issue with: $ DISPLAY=:0 wine tversion.exe Invalid MIT-MAGIC-COOKIE-1 key[tversion] MPFR 4.1.0-dev [tversion] Compiler: GCC 7.3-win32 20180506 [...] while there is no corresponding X server associated with :0. FYI, this happens when the test is run in GNU screen and the X server has shut down in the meantime. Even though there is a workaround (unset DISPLAY), there are two issues that should be fixed: 1. When X11 is not used like here, there is no reason to try to use DISPLAY (or at least, error messages should be deferred). Note that "env -u DISPLAY wine tversion.exe" doesn't output any error message. 2. As seen above, the error message does not end with a newline character. This breaks the parsing of the output (at least when both the standard output and the standard error are redirected to the same file). This is confirmed with: $ DISPLAY=:0 wine tversion.exe > /dev/null Invalid MIT-MAGIC-COOKIE-1 key% under zsh, where the "%" output by zsh means that the newline character is missing. I get the same issue with: $ DISPLAY=:0 xterm Invalid MIT-MAGIC-COOKIE-1 key/usr/bin/xterm: Xt error: Can't open display: :0 and with gxmessage (which doesn't use Xt), so that I assume that this comes from libX11. Reassigning this one to libx11-6. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
