On some laptops, the NVIDIA card may not correctly initialize during boot if the card was powered off when the system was last shutdown. Therefore the Bumblebee daemon will power on the GPU when stopping the daemon e.
Note that this setting does not influence power state while the daemon is running, so if all optirun or primusrun programs have exited, the GPU will still be powered off.
When you stop the daemon manually, you might want to keep the card powered off while still powering it on on shutdown. To achieve the latter, add the following systemd service if using bbswitch :. Then enable the nvidia-enable. The bumblebee daemon may fail to activate the graphics card after suspending.
One example configuration is below for two identical screens with p resolution and using the HDMI out. The BusID is Note that lspci outputs hexadecimal values, but Xorg expects decimal values. If you want to use all the displays on such a system simultaneously, the easiest solution is to use intel-virtual-output , a tool provided in the xfvideo-intel driver set, as of v2.
It will allow you to extend the existing X session onto other screens, leveraging virtual outputs to work with the discrete graphics card. Commandline usage is as follows:. If this command alone does not work, you can try running it with optirun to enable the discrete graphics and allow it to detect the outputs accordingly. This is known to be necessary on Lenovo's Legion Y If no target displays are parsed on the commandline, intel-virtual-output will attempt to connect to any local display.
The detected displays will be manageable via any desktop display manager such as xrandr or KDE Display. The tool will also start bumblebee which may be left as default install. See the Bumblebee wiki page for more information. When run in a terminal, intel-virtual-output will daemonize itself unless the -f switch is used. If intel-virtual-output does not detect displays, or if a no VIRTUAL outputs on ":0" message is obtained, then try editing the following two files as follows and rebooting :.
This article or section needs language, wiki syntax or style improvements. See Help:Style for reference. See [3] for further configurations to try. If the laptop screen is stretched and the cursor is misplaced while the external monitor shows only the cursor, try killing any running compositing managers.
If you do not want to use intel-virtual-output, another option is to configure Bumblebee to leave the discrete GPU on and directly configure X to use both the screens, as it will be able to detect them. As a last resort, you can run 2 X Servers. The first will be using the Intel driver for the notebook's screen.
Then, you can log in the integrated-graphics powered one. There is a known problem with some wine applications that fork and kill the parent process without keeping track of it for example the free to play online game "Runes of Magic".
This is a known problem with VirtualGL. As of bumblebee 3. If you are using the nouveau driver you could try switching to the nvidia driver.
Observe that the format of lspci output is in HEX, while in xorg it is in decimals. So if the output of lspci is, for example, 0a Add rcutree. You might encounter an issue when after resume from sleep, primusrun or optirun command does not work anymore.
For example, above command showed This could be because the nvidia driver is out of sync with the Linux kernel, for example if you installed the latest nvidia driver and have not updated the kernel in a while. A full system update , followed by a reboot into the updated kernel, might resolve the issue. If the problem persists you should try manually compiling the nvidia packages against your current kernel, for example with nvidia-dkms or by compiling nvidia from the ABS.
Consider switching to the official nvidia driver. As commented here , nouveau driver has some issues with some cards and bumblebee. You probably want to start a bit application with bumblebee on a bit system. See the "For bit If the problem persists or if it is a bit application, try using the primus bridge.
Your program forks into background and bumblebee do not know anything about it. Press F1 to open the options section, select Extended , and press F10 to apply this setting. The entire memory test can take a long time, so you can leave your PC unattended since your intervention will not be required. Once the test is complete, Windows 10 boots as usual and shows the test results in the notifications center.
But you can fix startup issues by running the Startup Repair tool from the Advanced Startup menu. Before doing so, you need an empty USB flash drive and Internet access to set up a system installation disk. Not only hard disk problems but also damaged, modified, or missing OS files can cause blue screen errors on your computer. Fast Startup is a Windows component that boots your operating system faster by pre-loading drivers.
If drivers are not properly shut down and restarted, it could trigger blue screen errors like nvlddmkm. Malware infections can be severe enough to corrupt critical system files and prevent you from running system tools like Task Manager or Command Prompt. If you suspect that your computer was recently infected with a virus, you should run a scan to eliminate any threats and regain the control of your PC. Missing, modified, corrupt, or incorrect registry settings can be devastating for your operating system and can even trigger blue screen errors like nvlddmkm.
But you can restore the original registry configuration from Command Prompt before system boot. You can easily test this by unplugging all external devices from your PC, except for your keyboard and mouse, in order to inspect results. If the keyboard and mouse are also brand new, try replacing them if you have others. System Restore allows you to revert Windows 10 to a checkpoint that was recorded before you started experiencing blue screen errors.
However, it means that System Restore must be enabled on your computer and at least one restore point must have been created prior to the BSOD event. If everything failed up until this point, you should prepare Windows 10 for factory reset in order to uninstall all programs and restore system settings to default. The good news is that your personal files will be left untouched.
But make sure to write down all applications you will have to install, save program preferences, and get hold of serial keys required for reactivation. Then, proceed to the following steps:.
To fix this problem, you can start Windows 10 in Safe Mode, run a clean system boot, check for system updates, disable overclocking software, reset and update BIOS, restore the nvlddmkm. In addition, you can disable Fast Startup and the PCI Express power option, run a computer malware scan, fix the system registry, unplug external devices, and use System Restore to roll back Windows 10 to a previous checkpoint.
If all these solutions fail, you can go to the last resort, which means resetting Windows 10 to factory settings. How did you manage to fix the nvlddmkm. View solution in original post. This package contains the driver that enables the Intel Dynamic Tuning firmware.
Intel Dynamic Tuning provides system temperature and power utilization information for the system thermal protection to function properly. This package is provided for supported computer models that are running a supported operating system.
The Intel Management Engine Interface enables communication between the host operating system and the Intel Management Engine firmware.
Please help to resolve the issue. Click on that device and click on the driver tab. Click on Update driver, select the Browse my computer for drivers option and browse to the driver folder that was created when you ran the file. Make sure the Include subfolders box is checked and see if the driver installs that way.
If that doesn't work either, please post the hardware ID's for the two devices needing drivers. This package contains the driver that enables the Intel Serial IO Drivers to be used with supported notebook models that are running a supported operation system.
I am going to have to download drivers and disassemble the file to see what driver has support for that specific hardware ID. Many thanks Paul, this time, it's a success. Installed all the drivers and no unknown devices in Device Manager. Didn't find what you were looking for?
