this is the system I am using. I have hard time with the drivers, currently I am using the nvidia 415 with the latest kernel. Problem is that it randomly freezes from time to time and I have not found how to fix that and also that the intel GPU is not recognized at all.

Any ideas?


mhwd seems to think you only have 1 gpu (nvidia) and didn’t install bumblebee stuff

so either try to install bumblebee (with that mhwd thingy) or configure manually (or try other distributions which don’t rely on mwhd)


already attempted to install bumblebee with mhwd, but it results in a blank screen.
Tried also ubuntu where there it installs nouveau driver initially and I have no control over brightness of the screen, and then later i installn nvidia drivers which again resulted in the system crashing from time to time(similar to what i have now)


brightness: “only” keys not working or in general not working?
(e.g. on my laptop keys only work if I use acpi_backlight=vendor in cmdline)

regarding of the crashing issue:
can you check if journalctl logged something which might help?
else you can try acpi_osi values,
(check output of sudo strings /sys/firmware/acpi/tables/DSDT | grep -E ‘Windows|Linux’ and try one of these) maybe it helps for your system crashing issue (probably wont).

sorry cant help with bumblebee issues (no clue about that)


Does this model have some BIOS options to turn off one of the GPU’s ? If so, then that might be the “issue”


@vetzki it is a problem with brightness in general, meaning I can not change it at all. (i have also attempted to install some apps that might help but they did not).

I have tried some of the flags for the acpi but could not find something working. Currently I have the following acpi_osi=! acpi_osi=\"Windows 2015\" but I dont know if it helps any, since the system crashed with and without it.

@bogdancovaciu yes there is a feature to turn off one of the GPUs but i do not want to do that, i am in dual boot with windows and I need both gpus in windows.


this is from the journalctl, after a crash just now

backlight, maybe try
acpi_osi=“Linux” acpi_backlight=vendor

(also check arch wiki backlight stuff
(but again this helps on my laptop, maybe also on yours. probably not.)

(you can edit cmdline when grub menu shows up after reboot so you dont have update-grub each time you test different values)

the crash log is useful (but unfortunately I’ve no clue how you can fix this error. Maybe wait for module update/try older nvidia kernel module[390xx not recommended] or if available test beta drivers)

you can also check nvidia forums if you find help for that issue:

according to this site
xid 79 can have lots of causes (hardware error, driver error, system memory corruption, …)
