![]() ![]() ![]() All of them suffer from usability issues. Valiant efforts such as Bumblebee, Nouveau and nvidia-xrun are in various states of disrepair - whether it is a performance issue or lacking support for modern graphics libraries such as Vulkan. In fact, the historical and current state (as at the year 2018) of using various proprietary and community-hacked open-source drivers on Linux is quite simply abysmal and confusing as hell. The proprietary Nvidia drivers for Linux however do NOT provide the same switching capability. But when that second monitor is unplugged, Windows can immediately and seamlessly shut off the Nvidia GPU and save power. On this laptop, the display ports are wired directly into the Nvidia card, so all operating systems are forced to turn on the Nvidia GPU in order to extend the display to another monitor. ![]() It can do this because the Nvidia drivers for Windows support this on-the-fly muxless switching functionality.īeing able to dynamically shut off the Nvidia GPU saves the battery considerably! However, when necessary (for example, when doing anything graphically intensive such as gaming), Windows will dynamically and seamlessly switch to using the Nvidia GPU for rendering. Windows has the ability to fully utilise Nvidia Optimus technology, use the Integrated Intel Graphics for rendering and completely shut off the Nvidia GPU. Windows has Full Control of the Nvidia GPU With a desire to run Linux (which regardless of this GPU discussion is known to be challenged regarding its power saving) I don’t expect this 4-cell battery to last all day… or even half a day while running a minimal load! However, I know from experience that I can squeeze at least a couple of hours of battery life out of the laptop when running a minimal load on Windows. My laptop is marketed as a ‘gaming laptop’ with a relatively power efficient 15.6” Sharp IGZO 4K display, an Intel 7th Gen Kabylake i7-7820HK, 32GB RAM (expandable to 64GB) and an embedded 4-cell 60Wh battery. for Data Science) without being forced to reboot or log off/on. ability to use the high performance of the Nvidia GPU (e.g.a good balance of display performance for normal daily work activities when the laptop is plugged-in – without excessive heat and the CPU or GPU fan spinning on high making a lot of noise when the simplest action of moving the mouse is performed.a couple of hours of battery life when unplugged.I have some fairly common and reasonable goals for the use of my laptop: What is PowerMizerDefault and PowerMizerDefaultAC ?.Configure an X11 configuration file for Nvidia driver How to Configure the Power Savings Modes?.Linux - Display Extended to External Monitor (Nvidia driver - Max Battery Savings).Linux - Display Extended to External Monitor (intel-virtual-output).Windows - Display Extended to External Monitor.Linux - Baseline - Integrated Intel Graphics Only.Windows - Baseline - Integrated Intel Graphics Only.Windows has Full Control of the Nvidia GPU.With adaptive VRAM clock control and integrated GPU performance state monitor, this application might come in handy for NVIDIA-equipped computers users. It can configure profiles per application can automatically apply power limits after booting the system. Setting GPU profiles for NVIDIA graphics cards is possible with this lightweight application. Manage and create custom profiles for NVIDIA GPUs It can reveal the state count and the GPU power draw, the average and the maximum power, and the GPU utilization rate, in percentages.Ī few other commands can be executed with NVIDIA GPU Power Management, which can display the current GPU clock speed and the performance state, lock and reset GPU or VRAM clocks, and print the SMI information. Not only that it can create GPU custom profiles, but NVIDIA GPU Power Management can also be used for monitoring GPU usage and power. The application allows adaptive VRAM clock when running applications that might require more graphics resources, such as popular web browsers (Chrome, Edge, Firefox) to play video content, Adobe CC applications or even custom apps of your choice. NVIDIA GPU Power Management allows you to set GPU power limits, both default, minimum and maximum values, but deeper control can be obtained in the “Control” tab, which makes it possible to configure power limit profiles for individual apps. The list of detected GPUs is displayed in a drop-down menu, allowing you to quickly select the one you need to tweak. The application is easily installed and once launched, it displays its intuitive, tab-based GUI. Set GPU power limits and define GPU custom profiles Creating custom GPU power profiles is possible due to the NVIDIA GPU Power Management application, which enables you to define power limits and configure profiles per application. Setting the correct power plan to match your activity and running tasks for your GPU can save power and make your system run smoother. ![]()
