'^@' characters constantly "typed" on VTs with kernel 4.13


Recent kernel upgrade (4.13) is disrupting VTs usage. The characters ^@ are constantly been typed son I can’t login (I doesn’t happen on X session). It stops when I press Shift-Lock key. Also, scrolling and tap clicking is really buggy on X. All of this goes away when booting 4.12 kernel. Default tumbleweed install; not even a month old one. The computer it’s a cheap laptop.

Anyone with the same issues?

Ok, I should have dug more deeply into the issue before posting. The peaq_wmi module is being loaded automatically and that’s what is causing all the weirdness. Anyhow, should it be reported? To whom?

Well, the module’s not loaded on my TW.
How do you update your TW ?

As recommended:

sudo zypper dup --no-allow-vendor-change

The strange thing is that the module doesn’t get automatically loaded with kernel 4.12, so I think it’s new (at least I saw some kernel work related to it here: https://github.com/torvalds/linux/blob/master/drivers/platform/x86/peaq-wmi.c)
It seems that my laptop has some ‘Cinema Mode’ or ‘Dolby Audio’ hardware keys, which I’ve never used before. Hell, I hadn’t even remembered them, being next to the power button.

The real question is: Should I report a bug in the opensuse tracker or should it be directly reported to the kernel one? Thanks.

As an interim measure, if you don’t need that module (and I confess I’ve no idea what it is) I guess you could blacklist it so it’s not loaded.

Create a file called, for example, “50-blacklist-peaq_wmi.conf” in /etc/modprobe.d

which contains the single line:

blacklist peaq_wmi

Already done that. Thanks for your suggestion nevertheless.:slight_smile:

It’s fixed now (sorry for the late replay).
