Output of dmesg on HP ZBook 15 G2
Just for the record: - Setting Hybrid Graphic to Disabled doesn't work around this problem. - The native nvidia driver 364.19 works fine for me. The bug discussed here still happens with kernel 4.6.0 but very rarely, while in 4.5.4 it happened reliably after a few minutes of using Chromium. Just an update: The total desktop freeze happens in kernel 4.6.2, but very frequently, after a few seconds/minutes of playing in Chromium or System Settings / Compositor Settings. OpenSUSE Tumbleweed 20160626, the same hardware: HP ZBook G2. Sounds like issue with multi-threading OpenGL support in nouveau, see #98039 -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

I upgraded from KDE 4 to KDE 5/Plasma. Since the nouveau driver keeps crashing and freezes everything. If I use the proprietary nvidia firmware (NvGrUseFw=1) together with the nouveau driver everything works fine. Normally, the crash heralds itself by some disrupted graphics (black boxes on the desktop) some seconds before everything freezes totally. The crash is usually triggered by some desktop effect if some item (menu/dialog/window) fades in or out ("transparency" effect). The crash usually occurs within the first five minutes after the login. Sometimes even the login crashes (sddm window manager) because the window manager uses the same fading effect and triggers the bug, too. My kernel version is 4.4.7. Graphic card: "ASUS GeForce GTX 660 PCI 3.0 2GB DDR5" uname: "Linux 4.4.7-gentoo #2 SMP Thu Apr 21 13:34:23 CEST 2016 x86_64 Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz GenuineIntel GNU/Linux" I also still suffer from bug #93629 and 93630 that also vanish if the proprietary firmware is used. But I decided to open a new bug, because the dmesg messages are different.
