My Hardware: * HP EliteBook 8440p * VGA compatible controller: NVIDIA Corporation GT218M [NVS 3100M] Installed software: * ArchLinux with all available updates * Kernel 3.15.1-1-ARCH * nouveau-dri 10.2.1-2 * xf86-video-nouveau 1.0.10-2 * lib32-nouveau-dri 10.2.1-3 My Log shows the following for nouveau when I suspend/resume the system: nouveau [ DRM] suspending display... nouveau [ DRM] unpinning framebuffer(s)... nouveau [ DRM] evicting buffers... nouveau [ DRM] waiting for kernel channels to go idle... nouveau [ DRM] suspending client object trees... nouveau [ DRM] suspending kernel object tree... nouveau [ DRM] re-enabling device... nouveau [ DRM] resuming kernel object tree... nouveau [ VBIOS][0000:01:00.0] running init tables nouveau [ VOLT][0000:01:00.0] GPU voltage: 850000uv nouveau [ PTHERM][0000:01:00.0] fan management: automatic nouveau [ CLK][0000:01:00.0] --: core 405 MHz shader 810 MHz memory 405 MHz nouveau [ DRM] resuming client object trees... nouveau [ DRM] resuming display... nouveau E[ PDISP][0000:01:00.0] DP:0006:0344: failed to read DPCD nouveau E[ PDISP][0000:01:00.0] DP:0006:0344: link training failed In my case there is NO external display and also NO docking station. It's the display of the laptop that remains black. For me, long-pressing the power button is the only way out of this situation.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
