Manjaro Gnome random freeze

Hi guys!
I recently installed manjaro gnome on an old windows tablet I have.
Despite the low ram and generally low power of this machine, almost everything worked very well out of the box.
I’m experiencing random freezes though: it doesn’t seem to be a specific application or process that causes the system to freeze and it doesn’t happen very often either. The tablet still suspend and wakes up if I press the power button but I can’t login or even safely reboot, the only option I have is an hard reboot. Another curious thing is that even though I can’t interact with the desktop at all, the clock and battery indicator still work fine, as if they’re not affected by it.
I’ve looked up other threads in the forum but they focus on other desktops or are related to nvidia drivers so they don’t apply to me and I don’t have the necessary troubleshooting skill to figure it out myself.
Wat can be the problem here?

here’s my inxi -Fazy, tell me if you need anything else

ps: I know 2 gigs of ram it’s not the best for gnome, but I intend to use this pc for manly reading documents, pdf and light browsing so I didn’t want to go through the pain of configuring KDE to work well with the touchscreen (still my favourite DE nonetheless XD)

2Gb can be enough for gnome if you configure it right and do only light tasks as you planned.

Do you have swap configured? If not, I recommend using a swapfile, as running out of ram is one possible cause for system freezes.

I also recommend using as few shell extensions as possible for maximum stability. Shell and gtk theme adwaita-maia can also be good for tablets, bacause of the larger titlebars.

To reduce ram usage, avoid using gnome-online-accounts and uninstall evolution-data-server. This will take gnome-calendar and geary with it, but it can about halve the idle ram usage of the desktop. Also make sure you are not using dynamic wallpaper, because it consumes about 300-400Mb ram for very little benefit.

I would start with those, and move to the actual troubleshooting of the freezes then, if the issue persists. In gnome, the solution to most problems is usually “go as vanilla as possible”.

Hi!
Thank you for your attention and sorry for the late reply…
I’ll sure try out what you told me, but this afternoon I was able to track down whats causing the freeze, although I really don’t know why.
This afternoon it happened 4 times that the system froze up when I opened the default file manager… a couple of times I just downloaded some files and I wanted to open them, the other times it froze just by clicking on the icon…
This is very strange, any ideas?XD

Also, I swap configured, 4 gigs in total and the I noticed that the system use it regularly, so no problem with that!

Little update:
this afternoon I tried to track down what was causing the freezing issue on this tablet and I think I found a solution.
I witched from Wayland to Xorg at login and it all seems fine now, the system feels snappier and it hasn’t froze for a while. I tried changing kernel but that didn’t help, in fact every Kernel except 5.4 LTS froze as soon as I clicked an icon!
So yeah, if anyone has this problem, unless you really wanna use wayland, this might be a solution for you!

If you are on a tablet like me and you installed iio-sensor-proxy for screen rotation, switching to xorg killed it for me. The solution is to install screenrotator package and screen rotation will work again!
