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.

If after installing the NVIDIA driver your system becomes stuck before reaching the display manager, try to disable kernel mode setting. Failure to start System will not boot after driver was installed
