Systems using switchable graphics require the usage of a special driver to use the Intel(R) video controller and the third party one you have in your system.
That special driver is provided only by your computer manufacturer, therefore you should contact your system manufacturer directly for assistance on this matter.
Please be specific with the "special driver" type we need to reach out to our manufacturers for. We are using after-market DisplayLink-powered docking stations to connect additional displays, e.g. Targus, so I doubt Samsung nor anyone else will offer something special.
Graphics drivers on Samsung's site just refer back to the out-of-box Intel driver. Please help.
In a nutshell,, Intel provides, inthis case, Nvidia the Intel HD Graphics driver to combine with the Nvidia Optimus driver for use on Switchable Graphics based systems.
Please see the following FAQ for additional information.
Hi Robert_U, and thanks for your response. I am having a similar issue (igfxext crashing with DisplayLink drivers installed), this time on a Lenovo machine.
However, I think there has been some confusion so far in this thread. The issue under discussion is NOT an issue with Switchable Graphics (for which I agree that the manufacturer needs to provide suitable drivers). My laptop does have switchable graphics, but that works just fine.
The incompatibility under discussion is instead seen when using an additional, *external* graphics card, connected via USB. This display should work at the same time as the Intel or discrete graphics adapter - on a separate monitor, of course - and mostly it does; the issue is that the "igfxext" process crashes repeatedly.
The support site for the USB graphics adapter has a page about this issue indicating that it is Intel that needs to provide an updated driver to fix this issue. Is that true? If so, what can we do to help this issue get resolved?
