Some of the commands that I have in Startup Applications do not start properly when I login. (In particular I am having trouble with gtk-redshift.) In order to debug, I would like to be able to view stdout/stderr. I haven't found a log file for Startup Applications. I have tried redirecting to a file using ">> log.txt" with no success.
How can I see stdout/stderr for a Startup Application? Better yet, is there a log file for Startup Applications?
