If ~/.xsession exists (my normal case) then the standard system /etc/X11/Xsession script will handle it one of two ways in 50x11-common_determine-startup. 1. If the file is executable then Xsession will exec it. This is normally what you want. 2. If the file is not executable then Xsession will run 'sh' on it. This sometimes confuses people who put bash specific syntax in the file but have it run by a POSIX compatible shell. Two questions: 1. Is your ~/.xsession executable? If not then it will be run by /bin/sh instead of by your choice in the #! line. 2. What are the contents of your ~/.xsession? It must be a complete session startup. It must at the least start a window manager. This would be a reasonable minimum size, minimum functionality file that sources your /etc/profile, ~/.profile (or ~/.bash_profile) files. The inclusion of '#!/bin/bash --login' places a login shell in the execution path and therefore loads up your login environment. #!/bin/bash --login exec x-session-manager Ensure that it is executable or the '#!/bin/bash --login' part will have no effect. This is a very important and often missed part! chmod a+x ~/.xsession Because this starts x-session-manager it will respect the Debian alternative settings for x-session-manager. update-alternatives --display x-session-manager But it is okay to hard code your own window manager choice there too. For example by using something very simple such as fvwm, just to furnish a hard example. #!/bin/bash --login exec fvwm Bob
