[reply] [−] Description t...@tim-richardson.net [reporter] 2017-09-03 10:46:21 UTC Created attachment 359016 [details] syslog reproduced on two Thinkpad laptops with bios set to Discrete graphics. In this mode, the integrated Intel graphics is bypassed by a hardware mux and the machines appears to have only Nvidia graphics. Environment is Ubuntu 17.10 development version, pre-release packages One laptop has Quadro 1000M, the other Quadro M1000M. Both cards are supported by the latest Nvidia drivers. Nvidia driver 375 or 384 (as packaged by Ubuntu) /etc/modprobe.d/zz-nvidia.conf has options nvidia_384_drm modeset=1 and after that setting sudo update-initramfs -u This problem does not occur when lightdm is used in instead of gdm3 or modeset=1 is not deployed. The session attempted to launch is either gnome or the new "ubuntu" desktop session, which is gnome The boot process fails.Sometimes there is just black screen (and high CPU activity driving the fans) and sometimes there is a message about NVIDIA persistence daemon starting and stopping, as well as gdm messages. I mounted the filesystem after a crash, and I attach syslog. In the attached syslog, search for persistenced to see messages like this Sep 2 12:42:15 tim-ThinkPad-W520 org.gnome.Shell.desktop[1206]: Window manager warning: Failed to create renderer: Failed to initialize renderer: Missing extension for GBM renderer: EGL_KHR_platform_gbm, Failed to find matching EGLDeviceEXT Sep 2 12:42:15 tim-ThinkPad-W520 gnome-shell[1206]: Failed to create backend: Failed to create MetaRenderer Sep 2 12:42:15 tim-ThinkPad-W520 systemd[1]: Starting NVIDIA Persistence Daemon...
