I can see X.org server starting on tty1. It prints some info about itself, then I'm switched to another console to login window.
X server logs some info to /var/log/Xorg.0.log, but not all of it. Various x-programs log their warning and error messages only to tty1, not to /var/log/Xorg.0.log
So how can I make X server log ALL messages to log file?
