Hello all,
First of all happy new year. Based on advice of Greg K-H herewith a mail
about my continuous (frustrating) issue with my laptop.
I installed various Kali linux versions up to Linux 4.20.0-rc7
(downloaded, compiled and installed) on a Samsung NP900X5N laptop and
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
saver) and stays black. I tried to fix it myself.and 'studied' the
behaviour for about 20 hours, I think it is a bug in the i915 module
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
in the same behaviour. Screen goes black.I do not see any logging in
the logs. I enabled ssh and the machine is unresponsive after the
screen going black. The more tests I do (rebooting via holding power
key) the sooner the screen goes black. I wonder if the gpu gets too hot
locally. Btw, the processor is not hot as the fan stays off.
- I tried changing various parameters in the i915 module. No luck. For
example, no compression, no power reduction.
- Guc/huc setting to 0x03 seems to delay the black screens but the black
screens continue.
- When I disable the driver in grub or in the modprobe.d dir I do not
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
machine on for more than 24 hours).
I would really appreciate some help here because the machine is unusable
with Linux. Furthermore my older NP900X4D is working with Linux for
almost 5 years now. I love linux and rather throw the machine away than
using Windows 10 :-)
ps: my Nouveau gives MMIO Faults so is not usable as well.
