Hi --
I'm kind of new to Arch & having this strange issue that I could use some help debugging. I'm running Arch with Xorg & Gnome on my laptop, and occasionally my mouse and keyboard abruptly stop responding to input. I can't move the cursor, use keyboard shortcuts, or even CTRL+ALT+F1 etc to get to a virtual console. My music player continues to play music and if I have a chat window open I keep getting messages from the person I'm talking with. Also, when I hit the power button on my laptop the gnome "shutdown/restart/logout" dialog pops up as normal, but I can't interact with it. My only option seems to be to hold the power button down until the machine shuts off & I can start it back up again.
I'm not sure what log files I'd look in to begin to troubleshoot this issue. I can't yet tell what's triggering the issue since it just pops up during normal use, and happens about once every two days or so. Any advice? Thanks!

USB devices can sometimes disconnect themselves for no apparent reason (not enough voltage?). Are your keyboard and mouse USB? Plugged into a hub? If yes, try plugging them directly on the motherboard...

Thanks for the tip. This is actually my built-in keyboard+trackpad on my laptop that are abruptly failing, not USB devices. I do use a USB mouse, but the machine doesn't respond to either the trackpad or the external mouse when this happens.

Sounds like a system lockup to me.

As llawwehttam says, this seems a system lockup.
I had the same symptoms a week ago. The machine would lockup any time between 10 and 60 minutes.

Solved by downgrading xorg-xinit to 1.3.0-1

Ooops, I somehow missed the "laptop" part... Laptop components can be "plugged" internally via USB though . Hopefully Mektub's suggestion will work.

Thanks, the issue in that other thread sounds exactly like what I'm experiencing. I'll try downgrading xorg-init.
