I then used this to create a patched runtime version of NVIDIA-Linux-x86_64-384.111.run, and used this on Kernel 4.16-rc4, and it compiled\/loaded OK, and – so far – is running without any problems..\u00a0 <\/span><\/p>\n

Tested with Kernel 4.16-rc4 (nopti), patched driver 384.111, on Fedora 27 with KDE\/Plasma, and VMware 4.1.1- running Win7 guest, with Photoshop CS6..

I should mention that I use VMware\/Win7\/Photoshop as a sort-of-benchmark-test for video drivers..\u00a0\u00a0 I have regularly tried using nouveau<\/strong>, but – although this runs OK in most cases – it causes all sorts of problems with Photoshop CS6 on a VMware 4.1.1 Win7 guest..\u00a0\u00a0 So.. I am staying with the proprietary NVIDIA drivers for the time being, on my main system..<\/em><\/p>\n
