![]() (EE) NVIDIA(0): system's kernel log for additional error messages and var/log/Xorg.0.log (EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module. You will see a message like the following in your logs only when Xorg runs during boot. On very fast booting systems, systemd may attempt to start the display manager before the NVIDIA driver has fully initialized. Xorg fails during boot, but otherwise starts fine The solution is at first reinstall latest nvidia-utils, and then copy /usr/share/X11//nf to /etc/X11//nf, and then edit /etc/X11//nf and add the line Option "PrimaryGPU" "yes". (EE) NVIDIA(G0): Failing initialization of X screenĪnd nvidia-smi says No running processes found (EE) NVIDIA(G0): GPU screens are not yet supported by the NVIDIA driver If /var/log/Xorg.0.log says X server fails to initialize screen X fails with "Failing initialization of X screen" Nvidia-xconfig -query-gpu-info could be helpful. To force Xorg throws error and shows you how correct it.Īfter re-run X see Xorg.0.log to get valid CRT-x,DFP-x,TV-x values. Xorg.0.log will provide more info.Īnother thing to try is adding invalid "ConnectedMonitor" Option to Section "Device" On a laptop it may be because your graphics card has VGA/TV out. If your graphics card has multiple outputs try plugging your monitor into the other ones. Sometimes NVIDIA and X have trouble finding the active screen. Screen(s) found, but none have a usable configuration See your bootloader Wiki page for more information. Note: The kernel parameters can be passed either through the kernel command line or the bootloader configuration file. Some hardware are easily damaged by overheating. The noacpi kernel parameter has also been suggested as a solution but since it disables ACPI completely it should be used with caution. The first one can be passed as a kernel parameter: User:Clickthem#nvidia moduleĪnother thing to try is to change your BIOS IRQ routing from Operating system controlled to BIOS controlled or the other way around. Turning it off in the BIOS has been confirmed to work for some users. If running a 64bit kernel, a driver defect can cause the NVIDIA module to fail initializing when IOMMU is on. with lspci -v) and pass allocation parameters to the kernel, e.g. In such case you should find out the amount of your system's video memory (e.g. In particular on systems with low video memory this can occur even if there is only one video processor. ![]() If there are too many video processors on the same system it can lead into the kernel being unable to start them because of memory allocation problems with the video controller. The problem can be a IRQ conflict with another device or bad routing by either the kernel or your BIOS.įirst thing to try is to remove other video devices such as video capture cards and see if the problem goes away. The NVIDIA documentation does not talk in detail on what you shouldĭo to correct this problem but there are a few things that have worked for some people. This error can occur for several different reasons, and the most common solution given for this error is to check for group/file permissions, which in almost every case is not the problem. (Discuss in Talk:NVIDIA/Troubleshooting#'/dev/nvidia0' Input/Output error. Reason: Verify that the BIOS related suggestions work and are not coincidentally set while troubleshooting.
