Seems like you're using the i915g driver - updating the component accordingly. As a temporary workaround, you can try the classic i915 driver? You're right, sorry. I'm not entirely clear on the difference. I switched to the classic driver, and with that both glxgears and KDE Plasma works. Same in NixOS https://github.com/NixOS/nixpkgs/issues/30758 (In reply to Karl-Johan Karlsson from comment #2) > You're right, sorry. I'm not entirely clear on the difference. I switched to > the classic driver, and with that both glxgears and KDE Plasma works. Clear can get called now with less state set in the driver. Many drivers weren't ready for this and had to be fixed. Looks like no one has fixed up i915g for a super-early clear call. I think this may relate to the problem described in this bug: https://bugs.freedesktop.org/show_bug.cgi?id=100189. It states there that the i915 Gallium driver is unmaintained, and may be removed from a future version of Mesa. In any case, I am running into exactly the same problem, which exposes itself by sddm-greeter crashing on startup, after a recent upgrade to Mesa 17.1.10. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

I'm trying to reinstall an old laptop (Lenovo Thinkpad X60, with a Core 2 Duo CPU) with a modern Gentoo Linux, but have run into a problem where every program trying to use OpenGL segfaults immediately. This makes running e.g. KDE 5 a bit difficult. TWM works, though, so I can get X, just not OpenGL. Here's what GDB thinks of glxgears, but every other program I've managed to debug crashes in the same way: (gdb) run Starting program: /usr/bin/glxgears [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate.
