Thank you for reporting this bug to Ubuntu. Ubuntu 17.10 (artful) reached end-of-life on July 19, 2018.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete ** Changed in: mesa (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1727365 Title: gnome-shell crashed with SIGSEGV in glsl_type::_vec4_type() from intel_update_image_buffers() from intel_update_renderbuffers() Status in gnome-shell package in Ubuntu: Incomplete Status in mesa package in Ubuntu: Incomplete Bug description: This bug is triggered for me by leaving the system inactive for a time and it happens whether the system settings is set to lock the screen or not, but I can be provoked by locking the screen. At the time when I want to reactivate the system (as I can see on the time stamp on the crash report), something happens and I loose the entire login session and am dropped at the login screen to login anew. This has lead me to believe that this has to do with re-enabling the display. The effect of this bug is that I loose *all* running programs in my session and has to start everything up again, which means that Ubuntu 17.10 is basically unusable for me. For this reason, of course depending on how many people are affected, I think this should be considered a high priority bug. This is a fresh install with no shenanigans except installing a few programs that I needed. I happy to provide any extra information is required and to any kind of testing that might be required as long as I can return to a non- modified system after test.
