Thanks for your report. I can reproduce this sometimes on Unity with LightDM and the Fcitx packages for Simplified Chinese. When it happens, ~/.xsession-errors looks like the attached file.
The explanation is a temporary file in /etc/profile.d for configuring input methods (see bug #1720250). LightDM checks for errors when sourcing that file, and apparently the launch of Fcitx results in messages written to STDERR (sometimes...). I have submitted a LightDM merge proposal to disable that error check for now. @Iain: Can you please look at this. I suppose that there is no LightDM release planned before release, so we should probably make an Ubuntu only upload with this one change. ** Also affects: lightdm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722427 Title: [error-report]error occurs when reading /etc/profile To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntukylin/+bug/1722427/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
