Also affected on a Hewlett-Packard HP Compaq dc7800p Convertible Minitower/0AACh, BIOS 786F1 v01.32 07/21/2011 with nvidia GeForce GT 520 board.
Workarounds by Rebecca Palmer at #5 (many thanks!) did not entirely suffice: Had to additionally add "blacklist nouveau" to /etc/modprobe.d/blacklist.conf even after sudo apt-get remove nouveau as well as de- and reselecting the proprietary one from System Settings / Software & Updates / Additional Drivers - which (even while the system was actually using nouveau) had been shown all the time as "Using NVIDIA binary driver - version 311.38 from nvidia-331 (proprietary, tested)" with a green light for "NVIDIA Corporation: GF119 [GeForce GT 520" and as "1 proprietary driver in use." Symptoms: nvidia-settings shows only minimal menu with no information on monitor(s) or GPU. prime-select query returns the string "unknown" rather than "nvidia". /var/log/syslog is flooded with lines (dozens per second) to the tune of "kernel: [ 1195.548660] nouveau W[ PFIFO][0000:01:00.0] INTR 0x01000000: 0x00000005". /var/log/syslog has these lines: kernel: [ 11.695523] NVRM: The NVIDIA probe routine was not called for 1 device(s). kernel: [ 11.695526] NVRM: This can occur when a driver such as: kernel: [ 11.695526] NVRM: nouveau, rivafb, nvidiafb or rivatv kernel: [ 11.695526] NVRM: was loaded and obtained ownership of the NVIDIA device(s). kernel: [ 11.695529] NVRM: Try unloading the conflicting kernel module (and/or kernel: [ 11.695529] NVRM: reconfigure your kernel without the conflicting kernel: [ 11.695529] NVRM: driver(s)), then try loading the NVIDIA kernel module kernel: [ 11.695529] NVRM: again. kernel: [ 11.695532] NVRM: No NVIDIA graphics adapter probed! kernel: [ 11.695850] NVRM: NVIDIA init module failed! nouveau (or possibly just some of the related mode-switching) is deprecated due to resume issues in Ubuntu 14.04 LTS (of which this is a fresh install) http://ubuntuforums.org/showthread.php?t=2217536&s=da1e9ef7ae0c51c40110e1b8e1347b47&p=12993037#post12993037 which are resolved only for a few in threads such as https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283938 (cf. #138 et seq. there) that like this one have been all too long-standing in an Unassigned state. Remaining issue now that the proprietary nvidia driver finally loads is that Systems Settings / Sound / Play sound through: "HDMI / DisplayPort2: <i>GF119 HDMI Audio Controller</i>" works only intermittently and for 2 rather than 5.1 channels. Any (auto-)tweak for the ELD (captured through the "Acquire EDID..." button from the DFP-1 menu of nvidia-settings) to be loaded from file (whichever comes in place of /etc/X11 these days) rather than by DDC would be very welcome. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1315156 Title: nvidia-331 selected but nouveau loads Status in “nvidia-graphics-drivers-331” package in Ubuntu: Confirmed Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: After upgrading to Trusty, I briefly used the nouveau driver to check whether bug 1243557 still existed; after finding that it did, I switched back to nvidia-331.
