Using artful, I updated these packages (everything that used to have version "17.2.2-0ubuntu1" on my system) to version "17.2.4-0ubuntu1~17.10.1" from -proposed: libegl1-mesa:amd64 libgbm1:amd64 libgl1-mesa-dev:amd64 libgl1-mesa-dri:amd64 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64 libgl1-mesa-glx:i386 libglapi-mesa:amd64 libglapi-mesa:i386 libgles2-mesa:amd64 libwayland-egl1-mesa:amd64 libxatracker2:amd64 mesa-common-dev:amd64 mesa-vdpau-drivers:amd64 mesa-vulkan-drivers:amd64
After a reboot, I can confirm Lawrence's observation that vulkan- smoketest segfaulted on the old version, but seems to work fine using the version from -proposed. Since Lawrence forgot to remove the verification-needed-artful tag, I'm going to remove it now. ** Tags removed: verification-needed-artful -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1720890 Title: vulkan-smoketest segfaults steam vulkan games segfault Status in mesa package in Ubuntu: Fix Released Status in mesa source package in Xenial: Fix Committed Status in mesa source package in Artful: Fix Committed Bug description: $ lsb_release -rd Description: Ubuntu Artful Aardvark (development branch) Release: 17.10 $ apt-cache policy mesa-vulkan-drivers mesa-vulkan-drivers: Installed: 17.2.1-0ubuntu1 Candidate: 17.2.1-0ubuntu1 Version table: *** 17.2.1-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu artful/universe amd64 Packages 100 /var/lib/dpkg/status Easily reproducible : apt-get install mesa-vulkan-drivers apt-get install vulkan-utils Open a terminal type vulkan-smoketest instead of a glxgears type window it will segfault. message from kernel.log: Sep 29 16:23:53 Tardis-1 kernel: [17709.532915] vulkan-smoketes[11798]: segfault at 0 ip 00007fed61a17914 sp 00007ffedcb8f850 error 6 in libvulkan_radeon.so[7fed619ab000+18b000] syslog: Sep 28 10:38:13 Tardis-1 kernel: [18292.174313] vulkan-smoketes[13385]: segfault at 0 ip 00007f62705a7914 sp 00007ffd0edc6260 error 6 in libvulkan_radeon.so[7f627053b000+18b000] What should happen is a glxgears like window will open and render properly instead of segfaulting. It appears that the culprit is an old or broken libvulkan_radeon.so provided by mesa-vulkan-drivers. As a test I renamed the old lib and dropped in a newer version from oibaf's ppa. smoketest now passes steam's The Talos Princible and Mad Max now work properly in Vulkan mode as well instead of segfaulting. This issue is also present on Zesty and fixed in both Oibaf's and Padoka's ppa's since April back when they were rolling 17.2 mesa. I have no idea if libvulkan_intel.so also needs updating no hardware to check.
