3 | # This is SORT OF LIKE an X session, but not quite. You get a command as the |

4 | # first argument (it could be multiple words, so run it with "eval"). As a |
---|
5 | # special case, the command can be: |
---|
6 | # default - Run the appropriate Xclients startup (see the code below) |
---|
7 | # custom - Run ~/.xsession and if that's not available run 'default' |
---|
8 | # |

---|
10 | # right now relevant and supported) |

12 | # The output is ALREADY redirected to .xsession-errors in GDM. This way |
---|
13 | # .xsession-errors actually gets more output such as if the PreSession script |
---|
14 | # is failing. This also prevents DoS attacks if some app in the users session |
---|
15 | # can be prodded to dump lots of stuff on the stdout/stderr. We wish to be |
---|
16 | # robust don't we? In case you wish to use an existing script for other DM's, |
---|
