The traditional kernel categories are monolithic kernels and microkernels with nanokernels and exokernels seen as more extreme versions of microkernels.
The "hybrid" category is controversial, due to the similarity of hybrid kernels and ordinary monolithic kernels; the term has been dismissed by Linus Torvalds as simple marketing. The idea behind a hybrid kernel is to have a kernel structure similar to that of a microkernel, but to implement that structure in the manner of a monolithic kernel.
In contrast to a microkernel, all or nearly all operating system services in a hybrid kernel are still in kernel space. There are none of the reliability benefits of having services in user spaceas with a microkernel. However, just as with an ordinary monolithic kernelthere is none of the performance overhead for message passing and context switching between kernel and user mode that normally comes with a microkernel. NT-based Windows is classified as a hybrid kernel or a macrokernel  rather than a monolithic kernel because the emulation subsystems run in user-mode server processes, rather than in kernel mode as on a monolithic kernel, and further because of the large number of design goals which resemble design goals of Mach in particular the separation of OS personalities from a general kernel design.
Conversely, the reason NT is not a microkernel system is because most of the system components run in the same address space as the kernel, as would be the case with a monolithic design in a traditional monolithic design, there would not be a microkernel per se, but the kernel would implement broadly similar functionality to NT's microkernel and kernel-mode subsystems. The Windows NT design includes many of the same objectives as Machthe archetypal microkernel system, one of the most important being its structure as a collection of modules that communicate via well-known interfaces, with a small microkernel limited to core functions such as first-level interrupt handling, thread scheduling and synchronization primitives.
This allows for the possibility of using either direct procedure calls or interprocess communication IPC to communicate between modules, and hence for the potential location of modules in different address spaces for example in either kernel space or server processes. Other design goals shared with Mach included support for diverse architectures, a kernel with abstractions general enough to allow multiple operating system personalities to be implemented on top of it and an object-oriented organisation.
On versions of NT prior to 4. For performance reasons, however, in version 4. Applications that run on NT are written to one of the OS personalities usually the Windows APIand not to the native NT API for which documentation is not publicly available with the exception of routines used in device driver development. An OS personality is implemented via a set of user-mode DLLs see Dynamic-link librarywhich are mapped into application processes' address spaces as required, together with an emulation subsystem server process as described previously.
Applications access system services by calling into the OS personality DLLs mapped into their address spaces, which in turn call into the NT run-time library ntdll. The NT run-time library services these requests by trapping into kernel mode to either call kernel-mode Executive routines or make Local Procedure Calls LPCs to the appropriate user-mode subsystem server processes, which in turn use the NT API to communicate with application processes, the kernel-mode subsystems and each other.

No frame, nothing, just a black rectangle. If I guess and click the right part of the window, the More menu will pop up and is readable, but choosing Settings just returns me to a black window. I have tried reinstalling.
I have tried launching with --disable-gpu command line option. My vintage HP Z workstation does not have this problem. None of my other programs, including Office, is showing any changed behavior.

I was able to resolve this by booting in Windows safe mode, where I could see the browser window. There, I set all Chrome settings to default and removed the theme.Hybrid-graphics is a concept involving two graphics cards on same computer.
Laptop manufacturers have developed new technologies involving two graphic cards with different abilities and power consumptions on a single computer. Hybrid-graphics has been developed to support both high performance and power saving use cases. There are a variety of technologies and each manufacturer developed its own solution to this problem. This technology is well supported on Windows but it's still quite experimental with Linux distributions.
The first generation of notebooks with hybrid graphics follow an approach that involves a two graphic card setup with a hardware multiplexer MUX. The switch is done in a workflow similar to the following:.
This switch is somewhat rough and adds some blinks and black screens in laptops that could do it "on the fly". Later approaches made the transition a little more user-friendly. Most of the new Hybrid-graphics technologies involve two graphic cards as the basic switching but now the DGP and IGP are plugged to a framebuffer and there is no hardware multiplexer.
In most cases there is no way to use only the DGP and all the switching and rendering is controlled by software. At startup, the Linux kernel starts using a video mode and setting up low-level graphic drivers which will be used by the applications. Most of the Linux distributions then use X. Finally, a few other softwares are launched, first a login manager and then a window manager, and so on.
This hierarchical system has been designed to be used in most of cases on a single graphic card. With a NVidia GPU, this can be more safely done using bbswitchwhich consists of a kernel package that automatically issues the correct ACPI calls to disable the discrete GPU when not needed, or automatically at boot.
The script will go through all the known data buses and attempt to turn them off. You will get an output similar to the following:. See the "works"? This means the script found a bus which your GPU sits on and it has now turned off the chip.
To confirm this, your battery time remaining should have increased. Currently, the chip will turn back on with the next reboot. To get around this, add the kernel module to the array of modules to load at boot:. To turn off the GPU at boot it is possible to use systemd-tmpfiles.
The above config will be loaded at boot by systemd. On some systems, turning off the discrete GPU before the X server is initialized may hang the system.
In such cases, it may be better to disable the GPU after X server initialization, which is possible with some display managers.
In LightDMfor instance, the display-setup-script seat configuration parameter could be used to execute a script as root that disables the GPU. Note: This model is utilized by most manufacturers as of See also DKMS. Category : Graphics.

You can reach us at For background, some Dell laptops have a feature where they use a low-powered intel graphics card when undemanding applications are running, but they switch to a high-power, high-wattage graphics card AMD Radeon series when demanding games are running.
Dell engineers have to specificaly craft a version of the intell driver installers that is compatible with this configuration. If you just use the vanilla Intel video drivers, they won't respect the AMD wish to take control of graphics and the AMD video card will sit unused in your laptop. There are three parts to getting Windows to use your preferred driver for the hardware, one is removing any installed software that provides drivers.
This is done by uninstalling all software that puts drivers on the hard drive. The second step is to delete any drivers that windows is pegged against because Windows will not allow drivers it is using to be fully uninstalled. This is done by putting Windows into "safe mode" where it does not use most drivers and then uninstalling and deleting the driver files themselves.
I think I've heard that switchable graphics can change if on battery power, not sure. Skyrim worked fine after doing this, and l4d2's intros ran very smoothly they're incredibly choppy when they run on the intel graphicsbut the app itself crashed without warning to the desktop just as it finished loading a single-player campaign for me.
I suspect that this is probably more a windows 10 thing than an graphics thing and I hope reinstalling the game will fix it. Go to Solution. Well, my case is very simple. I just install the newest driver from Intel. View solution in original post. Wow, it would be great if switchable graphics no longer required a specialized Intel driver. I'd like to think Windows 10 made drivers better, but the pessimist in me has some doubts.
I've definitely been in a state where the switchable graphics option is on the desktop right-click menu and the AMD drivers appear to be working, but when I run games, the Intel drivers don't cede control to the AMD display adapter. It will be extremely choppy on Intel graphics at p. Have you done this? Huh, maybe things have actually gotten better. However, it means we aren't at the mercy of Dell for driver updates, which would be awesome. Also, things that are built into the intel chipset that were unusable for me at least due to the weird driver configuration may work now, such as WiDi.
Previously Dell didn't build an Intel driver that supported WiDi, and when I tried to install a vanilla Intel driver that did, I would break switchable graphics. I'll have to give WiDi a try. I've been using Photoshop, Solidworks, and the switchable graphics can switch automatically. I played Dota 2 in my pervious Win 8.
