Xorg Random Crashes by libinput

Mindstormscreator · 2018-09-20 18:17:25

I believe I'm seeing a very similar issue to the following threads where libinput < 1.10 crashes Xorg, although this looks slightly different and libinput is fully upgraded to the latest version (1.12.0-2).

I don't think the reported kernel bugs are coincidence. There have been a lot of touchpad/HID fixes in the 4.18.9 update. Do at least update to that and check if you can reproduce.

I tried just upgrading to that kernel today and upgraded back to latest libinput, unfortunately I still see crashes. Before upgrading to this kernel, downgrading from libinput 1.12.0-2 to libinput 1.12.0-1 seemed to have mitigated the crashes, so I think it's libinput still.

Update: it still appears to happen even with libinput 1.12.0-1.

So I've noticed in the xorg log that there are consistenly a bunch of messages about a "cursor jumping kernel bug" a few minutes before the crash.

I have a suspicion that I am suffering a similar fate with libinput. Here is the error log I saved from my first xorg crash (ever!) with arch linux so far. At line #444, you'll notice I get the same kernel bug about a jumping cursor.

My only variation on this error with libinput is that I have a bluetooth mouse and I am wondering if this could also cause xorg/libinput to be misbehaving. I just so happened to get this mouse at exactly the same time this started to occur (~week ago, only two times so far), and it aligns with the last event in the xorg log file before the stack trace.

I'll be updating the linux kernel tonight and will report back if I notice any new issues/lack of crashing. Luckily(?) the crashes are very sparse, but that makes figuring out why they are happening all the harder for me.

Very interesting, I also recently bought a bluetooth mouse also arguably around the time I've seen the crashes. The crashes happen when the mouse is disconnected and I'm just using the touchpad though.

I'm going through the same issue (exact same stacktrace on Xorg.log/journalctl). I tried to downgrade to libinput 1.11.903 but I still got the same crash. I've recorded a evemu recording which seemingly reproduces the crash 100% of the times (crash.evemu). Oh, and I don't have a bluetooth mouse at all, I only use the touchpad on my notebook.

There is an upstream bug report: https://gitlab.freedesktop.org/libinput … issues/150

Fix appears to have been merged into master: https://gitlab.freedesktop.org/libinput … quests/111
