Black screen problem
I installed my arch linux 2 days from now, i'm using gnome in my samsung expert x30. When i'm using my laptop sometimes i get a black screen from nowhere, somenthing is written(like when i turn on my arch) but i can't read because it's too fast, after this the gnome login screen appears but i can't login, the only way i can do it is rebooting. I can't see the pattern envolving this black screen, i can use my laptop for hours and this comes from nowhere, no pattern.

Re: Black screen problem
I don't now how i see
Edit:
I learned how to see it and i think is something related to crash dumped in things realated to gnome.

Re: Black screen problem
The idea is that you specify to us what is "crash dumped in things realated to gnome" and yes, it's very most likely a segfault of gnome-shell why you'll next learn about "cordumpctl" and share the coredump of such crash 
If it's in libgjs and your mozjs38 version is up-to-date, it's most likely a problem with some (non-stock?) extension, there're quite some recent threads on the matter.

Re: Black screen problem
You can either build the js38 package with debug en- and stripping disabled to gain more information on why it crashes, or try to identify the triggering extension by removing/disabling them all, see whether gnome-shell still crashes and (if not) enable them one-by-one until the crash re-occurs.

Re: Black screen problem
i have no idea how to debug the package. I'm going to try disable the extensions, but keeping in mind that the crash occurs maybe one/two times a day, this will require a lot of time.
