Mouse and keyboard input occasionally stops working

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!

Re: Mouse and keyboard input occasionally stops working

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...

Re: Mouse and keyboard input occasionally stops working

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 smile. Hopefully Mektub's suggestion will work.

Re: Mouse and keyboard input occasionally stops working

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