<div dir="ltr">Hi,<br><br>My KDE desktop environment crashes or freezes roughly once per day or 2, even though I am using Debian 7.0 Stable with nearly all my software just from the Wheezy sources including the kernel, Intel driver, NVIDIA driver and CUDA Toolkit, except for Bumblebee and Skype and a few others.<br>
<br>I'm using a Lenovo ThinkPad W520 laptop that has a Quadro 1000M GPU with Optimus technology, so my desktop environment is actually using my Intel GPU and I use my NVIDIA GPU just for CUDA development through Bumblebee using "optirun ...".<br>
<br>Plasma suddenly died on me just now (or atleast that's what I thought happened, since my computer was still working but window decorations and KDE start menu and similar were not visible). After looking into Xorg.0.log I saw the error message:<br>
(EE) intel(0): Detected a hung GPU, disabling acceleration.<br> (EE) intel(0): When reporting this, please include i915_error_state from debugfs and the full dmesg.<br><br>At the time of this event, it happens that I was writing CUDA code and
had done my last CUDA test just 1 or 2 minutes before this crash. ie: my
NVIDIA GPU would have been off at the time of this crash, but it was on just minutes before the crash. I am using KDE with KDM & KWin and I am using "OpenGL" as the
renderer in KWin settings, with "mesa-diverted" as my GL library.<br>
<br>So where should I file my bug report, since it might be related to Bumblebee or Intel or NVIDIA or Debian packages?<br><br clear="all"><div><br>Cheers,<br>Shervin Emami.<a href="http://www.shervinemami.info/openCV.html" target="_blank"></a></div>
