dmesg
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.
A summary of the test I performed.
- I tried several versions and distributions. They all result in the same
behavior. 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.
- When I disable the driver in grub or in the modprobe.d dir I do not have
experience any hangs.
- With Windows 10 the machine does not results in lockups (kept the machine on
for more than 24 hours).
I added drm.debug=14 module parameter, attach /var/log/messages file from boot
to desktop to the bug.
When the machines hangs, no ssh is possible. Copied the file afterwards.
The syslog is attached</pre>
