Seemingly random X server freezes/crashes - "EQ overflowing"

tlater · 2014-11-01 00:14:35

I assume not knowing where a question belongs screams "Newbie Corner", doesn't it?

I am running a relatively fresh Arch setup with Awesome wm, and recently my X-server has started freezing up completely randomly. The only pattern I have been able to see is that I usually have Google+ opened in the active Firefox tab, but considering that I find myself there comparably often and I can see no way in which a specific page on a specific browser could crash the X server (although, when I once had the wm survive through one of the freezes a pop-up informed me that a script on the Google+ page had caused problems, I unfortunately could not take any notes in time though since another freeze occured immediately after and actually crashed this time), it could just be a coincidence.

I have had the problem for a while now, but after a recent upgrade it seems to have become more frequent. Due to this install only being about a month old I've installed quite a lot and I have upgraded twice since the initial "problematic" upgrade, so I don't believe I could find a culprit very easily.

I do have an Xorg log with the error that seems to cause it ("(EE) [mi] EQ overflowing. Additional events will be discarded until existing events are processed"), but Google results don't match my problem and I don't know much about the X server so I will not be able to come up with a solution myself. This is my error log.

Interestingly, mpd seems to get stuck in a loop as well when this happens, which to my understanding it should not since the two are not related. Do correct me if they are, of course.

At this point I really don't know what else to do, the only hints I have left is that according to my log I replugged my mouse just before it happened the last time, but I don't believe it's the problem since that did definitely not cause it before, and the fact that I have a faulty driver for my touchpad, which has been a problem since the beginning I've been too lazy to fix so far (so much more exciting stuff to play with!).

So, if you've read this far I'd really like to thank you for taking the time to do so and I hope you can tell me what the hell is making my Arch Linux look like Windows... This better not happen when I'm trying to show off, seriously.

Is this ATI graphics, or what video card/driver? If this is ati/radeon, it looks a lot like this other thread with a solution:

I've already seen that thread, no, I run a laptop with Intel integrated graphics. The display also doesn't flash, the whole environment seems to slow down at first and then just brings me back to the tty I started x from (with a bunch of error messages, of course).

What errors, if any, get printed to the journal?

pulseaudio and alsa seem to have problems, 5 minutes before the latest crash I have 3 sections looking like this:
