Based on advice of Greg K-H herewith a mail=20 about my continuous (frustrating) issue with my laptop. I installed various Kali linux versions up to Linux 4.20.0-rc7=20 (downloaded, compiled and installed) on a Samsung NP900X5N laptop and=20 have an issue with the driver after loading. My configuration: - i7 7500 - 16 gb / 256 gb ssd - nvidia 940MX (for 3D graphics) Shortly after loading the module the screen goes black (af if screen=20 saver) and stays black. I tried to fix it myself.and 'studied' the=20 behaviour for about 20 hours, I think it is a bug in the i915 module=20 itself. I consider it much more efficient to ask you guys for some help. A summary of the test I performed. - I tried several versions and distributions (about 7). They all result=20 in the same behaviour. Screen goes black.I do not see any logging in=20 the=C2=A0 logs. I enabled ssh and the machine is unresponsive after the=20 screen going black. The more tests I do (rebooting via holding power=20 key) the sooner the screen goes black. I wonder if the gpu gets too hot=20 locally. Btw, the processor is not hot as the fan stays off. - I tried changing various parameters in the i915 module. No luck. For=20 example, no compression, no power reduction. - Guc/huc setting to 0x03 seems to delay the black screens but the black=20 screens continue. - When I disable the driver in grub or in the modprobe.d dir I do not=20 have any black screens. - After closing and opening the lid the machine does not wake up. - With Windows 10 the machine does not results in lockups (kept the=20 machine on for more than 24 hours). I would really appreciate some help here because the machine is unusable=20 with Linux. Furthermore my older NP900X4D is working with Linux for=20 almost 5 years now. I love linux and rather throw the machine away than=20 using Windows 10 :-) ps: my Nouveau gives MMIO Faults so is not usable as well. --=20 Met vriendelijke groet, *dr.
