** Description changed: + [Impact] + + This is the #1 crasher of gnome-shell in Ubuntu 20.04, though it's + duplicated across multiple problem reports according to locale: + https://errors.ubuntu.com/problem/4de3d315d9df1c9699bda54beafeeeea8d52053c https://errors.ubuntu.com/problem/2251b638f7a6167772f922dc5916740522c5c22b https://errors.ubuntu.com/problem/943838b8a80c1da4f8df584b7d2ad3a13361fdd7 https://errors.ubuntu.com/problem/4b78bc9730e8681f0c42fc2ecea14d03544394f0 - --- + [Test Case] - The Ubuntu Error Tracker has been receiving reports about a problem regarding gnome-shell. This problem was most recently seen with package version 3.36.1-5ubuntu2, the problem page at https://errors.ubuntu.com/problem/4de3d315d9df1c9699bda54beafeeeea8d52053c contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports. - If you do not have access to the Ubuntu Error Tracker and are a software developer, you can request it at http://forms.canonical.com/reports/. + None known. The plan is to just continue monitoring crash reports. + Still, we are confident this is the fix because: + + * The offending source code in libx11 tells us it is :) and + * The crash only started in Ubuntu with gnome-shell 3.34, which is the + exact release in which XInitThreads was removed from mutter. + + [Regression Potential] + + Low. We add a single function call that tells libX11 to enable thread + safety. This same function call is one we had in bionic, cosmic and + disco.
