** Description changed:
+ trusty and utopic SRU requests
+ ==============================
+
+ [Impact]
+
+ In case of a syntax error in either of ~/.profile or a few other similar
+ files, the Xorg login is interrupted, and the user is taken back to the
+ login screen without an explanation. Debugging this problem may be a
+ time consuming exercise, especially for non-experienced users.
+
+ With the proposed change, lightdm/gdm does not try to load such a file,
+ but shows a warning dialog instead. (A warning dialog is also shown in
+ case of some other type of error, which would not have caused the login
+ to fail.)
+
+ [Test Case]
+
+ To reproduce:
+
+ * Edit ~/.profile and add something bad, e.g. a non-closed parenthesis.
+ * Log out and find that you can't log in to a graphical session.
+
+ After installing the proposed lightdm/gdm version, you'll instead see
+ the dialog and can log in.
+
+ [Regression Potential]
+
+ Since this is only about improved exception handling, it does not at all
+ affect users with correct configuration files. The regression risk ought
+ to be minimal.
+
+ [Original description]
+
Binary package hint: gdm
After adding "function AddPath { PATH="$1:$PATH" }" to $HOME/.profile
made the Xorg startup fail. (At that moment I had already forgotten the
changes made to the .profile). As I had autologin that meant it kept
trying to login and finally showed me the graphics reconfiguration
screen. That sent me to a huge hunt for xorg conf and setup problems.
Anyway finally tracked this down. I had used bash syntax in .profile
file whereas it was run with sh.
This is not a bug per se but I think a user mistake in ".profile"
shouldn't bring the whole xorg startup to a halt as it does with
autologin. I propose running user ".profile" and ".xprofile" scripts so
that Xsession script continues running even if they have errors. I'm not
sure whether this change would have some negative effects as well.
