History question again. Does anybody know when .xsession-errors were started. The oldest I can find about from
/usr/share/doc/xserver-xorg/ is from 2005 which tells about the X11R7.0.0 release . Does anybody know what used to the state before that ?
In the old X Consortium upstream sources, it was added in 1991 to replace logging to a system-wide log file that users might not have access to:
but that had only been introduced a month before, and hadn't made it out into a release yet:
before that, it appears to be as @WumpusQ.Wumbley said in the comment above - it wasn't being captured by the Xsession and instead either lost or logged with the xdm stderr logs.
$XConsortium: Xsession,v 1.7 92/08/06 11:08:14 gildea Exp $. What preceded it was apparently the user session just inherited stderr from the
xdmdaemon, which caused error messages to get lost to /dev/null or in some system log file or on the console where the user couldn't see them.
.xsession-errorsfile lying around here in an archived home directory that was last written on 27 October 2000. I could probably find another one somewhere that is closer to the 1992 date but I'd have to dig in offline archives.
xconsoleso they could keep track of messages logged to the console. You could turn your comment into an answer, that's as good as it's going to get I think...
