Apparently it's one of those things that GCC permits whereas Clang does not: I had my default compiler set to Clang, and setting it back to GCC allowed the compilation to proceed without problems.
I thus backported the 0.4.9.2+git20140410-0ubuntu2 version from Utopic to Trusty and now my new color settings are preserved, but I have to ensure that the iGtk line mentioned above is removed. (It is not regenerated at next login/reboot). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1316384 Title: After upgrade from Lubuntu 13.10 to 14.04, color customization is ignored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxsession/+bug/1316384/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
