Public bug reported:
Jammy Jellyfish 22.04.1 LTS and others. There have been numerous bug
reports and failed fixes for this over several years and releases.
There are a couple of problems in /etc/X11/Xsessions where it fails to
handle options, causing bogus error messages and, doubtless, many
errors.
The first bug is that the entire options file, including comments, is
read into a variable.
Where the variable "OPTIONS" is assigned;
Replacing "cat" with "grep" strips out comments and blank lines;
$ diff Xsession Xsession.orig
65c65
< grep -v "^\s*\#\|^\s*$" "$OPTIONFILE"
---
> cat "$OPTIONFILE"
The second problem is that checking for a non-existent directory inside
a command substitution does not work. It just appends garbage onto the
output string.
That is probably a bug in BASH, but I defer to your opinion there.
The immediate work around is to create an empty directory so that the
test does not fail. Better still, force the creation of the directory
and remove the test.
eg. change this;
OPTIONS="$(
if [ -r "$OPTIONFILE" ]; then
cat "$OPTIONFILE"
fi
if [ -d /etc/X11/Xsession.options.d ]; then
run-parts --list --regex '\.conf$' /etc/X11/Xsession.options.d | xargs -d
'\n' cat
fi
)"
to this;
OPTIONSDIR=/etc/X11/Xsession.options.d
mkdir --parents ${OPTIONSDIR}
OPTIONS="$(
if [ -r "$OPTIONFILE" ]; then
grep -v "^\s*\#\|^\s*$" "$OPTIONFILE"
fi
run-parts --list --regex '\.conf$' /etc/X11/Xsession.options.d | xargs -d
'\n' cat
)"
