2015-02-17 01:44:59 Erick Brunzell description I've been testing the Ubuntu GNOME Vivid daily images in anticipation of Alpha 2 and I noticed that with this specific hardware I get no graphics at all other than a blank screen (see attached photo): AMD Sempron Processor LE-1250 @ 2.2 GHz nVidia C61 [GeForce 7025 / nForce 630a] (rev a2) nVidia MCP61 High Definition Audio (rev a2) nVidia MCP61 Ethernet (rev a2) 2GB DDR2 RAM In fact I never even get as far as the screen offering to Try or Install, but I can enter the Advanced Boot Options screen and select either Try or Install from there, but with both options I still get the same blank screen. Further testing reveals the same results with Ubuntu and Ubuntu GNOME but I found that both the Xubuntu and Lubuntu images will boot properly on this box so I installed Lubuntu and then installed the ubuntu-desktop, ubuntu-gnome-desktop, and gnome-session-flashback meta-packages just to try some things. After doing so I found that the Unity, GNOME Shell, Gnome Classic, and Flashback w/Compiz sessions produce broken graphics just as the Ubuntu GNOME and Ubuntu live images do. So basically Compiz and Mutter both fail to display any usable UI. OTOH both the Lubuntu and Flashback w/Metacity sessions work just fine. I next opened the Additional drivers UI and chose nvidia-304.125 (current) and all DE's perform quite well with the proprietary drivers so I deduced that nouveau might be the culprit. The last known working Ubuntu and Ubuntu GNOME live images are 14.04.1. I hadn't tried Utopic on this box yet but it's also a fail. I'll try the proposed 14.04.2 images ASAP (probably after Vivid Alpha 2 is released). But I see no point in trying to fix this for Utopic (or even 14.04.2 if it's effected) because of the 9 month life-cycle for Utopic and the continued availability of the 14.04.1 images. In fact I'd be cool with this not being fixed until 16.04 as long as it's documented so people know what versions will and will not work. I'm probably forgetting something but that's all I can think of ATM. Sorry in advance if I did this totally wrong.

There are almost certainly other instances of screen corruption and hard (or soft) lockups that may also be related to the nouveau driver but those are beyond the scope of this specific bug report. To workaround this bug, or to see if you're affected by it you can boot using this boot parameter: nouveau.config=NvMSI=0 You'll find general instructions for using custom boot parameters at these links: https://help.ubuntu.com/community/BootOptions https://wiki.ubuntu.com/Kernel/KernelBootParameters In addition to what's said at the latter link about temporarily adding a kernel boot parameter to an installed system; after using the arrow keys to navigate to the line beginning with "linux /boot" you'll notice that line ends with "quiet splash $vt_handoff".

There are almost certainly other instances of screen corruption and hard (or soft) lockups that may also be related to the nouveau driver but those are beyond the scope of this specific bug report. To workaround this bug, or to see if you're affected by it you can boot using this boot parameter: nouveau.config=NvMSI=0 You'll find general instructions for using custom boot parameters at these links: https://help.ubuntu.com/community/BootOptions https://wiki.ubuntu.com/Kernel/KernelBootParameters In addition to what's said at the latter link about temporarily adding a kernel boot parameter to an installed system; after using the arrow keys to navigate to the line beginning with "linux /boot" you'll notice that line ends with "quiet splash $vt_handoff". The boot parameter belongs between the "quiet splash" and "$vt_handoff" like this: quiet splash nouveau.config=NvMSI=0 $vt_handoff ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2 ProcVersionSignature: Ubuntu 3.18.0-9.10-generic 3.18.2 Uname: Linux 3.18.0-9-generic i686 .tmp.unity.support.test.0: ApportVersion: 2.15.1-0ubuntu2 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: GNOME-Flashback:Unity Date: Mon Jan 19 17:41:32 2015 DistUpgraded: Fresh install DistroCodename: vivid DistroVariant: ubuntu ExtraDebuggingInterest: Yes, if not too technical GraphicsCard:  NVIDIA Corporation C61 [GeForce 7025 / nForce 630a] [10de:03d6] (rev a2) (prog-if 00 [VGA controller])    Subsystem: Biostar Microtech Int'l Corp Device [1565:1405] InstallationDate: Installed on 2015-01-19 (0 days ago) InstallationMedia: Lubuntu 15.04 "Vivid Vervet" - Alpha i386 (20150118) Lsusb:  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub  Bus 002 Device 002: ID 046d:c52e Logitech, Inc.  Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub MachineType: BIOSTAR Group N68SB-M2S ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.18.0-9-generic root=UUID=acf0fd65-0d6d-4da6-9532-2adc558bc0a7 ro quiet splash init=/lib/systemd/systemd SourcePackage: xserver-xorg-video-nouveau UdevLog: UpgradeStatus: No upgrade log present (probably fresh install) XorgLogOld: dmi.bios.date: 06/24/2010 dmi.bios.vendor: Phoenix Technologies, LTD dmi.bios.version: 6.00 PG dmi.board.name: N68SB-M2S dmi.board.vendor: BIOSTAR Group dmi.chassis.type: 3 dmi.chassis.vendor: BIOSTAR Group dmi.chassis.version: N68SB-M2S dmi.modalias: dmi:bvnPhoenixTechnologies,LTD:bvr6.00PG:bd06/24/2010:svnBIOSTARGroup:pnN68SB-M2S:pvr:rvnBIOSTARGroup:rnN68SB-M2S:rvr:cvnBIOSTARGroup:ct3:cvrN68SB-M2S: dmi.product.name: N68SB-M2S dmi.sys.vendor: BIOSTAR Group version.compiz: compiz 1:0.9.12.0+15.04.20141219-0ubuntu1 version.libdrm2: libdrm2 2.4.58-2 version.libgl1-mesa-dri: libgl1-mesa-dri 10.3.2-0ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.3.2-0ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.16.2.901-1ubuntu3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.0-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.4.0-2ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917-1~exp1ubuntu2 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2 xserver.bootTime: Mon Jan 19 17:37:11 2015 xserver.configfile: default xserver.devices:  input Power Button KEYBOARD, id 6  input Power Button KEYBOARD, id 7  input Logitech USB Receiver KEYBOARD, id 8  input Logitech USB Receiver KEYBOARD, id 9 xserver.errors:  Failed to load module "nvidia" (module does not exist, 0)  Failed to load module "nvidia" (module does not exist, 0) xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.16.2.901-1ubuntu3 xserver.video_driver: nouveau
