Smile how do I stop evdev events being repoted in dmesg, and being logged to syslog


Hi, how do I stop these events being repoted in dmesg, and being logged to syslog?

I think it is logging events from mouse, keyboard and joystick actions.

Code:
evbug.c: Event. Dev: input1, Type: 1, Code: 31, Value: 0
evbug.c: Event. Dev: input1, Type: 0, Code: 0, Value: 0
evbug.c: Event. Dev: input1, Type: 4, Code: 4, Value: 34
evbug.c: Event. Dev: input1, Type: 1, Code: 34, Value: 1
evbug.c: Event. Dev: input1, Type: 0, Code: 0, Value: 0
evbug.c: Event. Dev: input1, Type: 4, Code: 4, Value: 34
evbug.c: Event. Dev: input1, Type: 1, Code: 34, Value: 0
evbug.c: Event. Dev: input1, Type: 0, Code: 0, Value: 0
evbug.c: Event. Dev: input1, Type: 4, Code: 4, Value: 28
evbug.c: Event. Dev: input1, Type: 1, Code: 28, Value: 1
evbug.c: Event. Dev: input1, Type: 0, Code: 0, Value: 0
as mentioned in another thread, my logs are full of this and I can't see the real info.

<edit>
upon reading the man page, there is no mention of logging.
The manpage supposes the evdev module is loaded from/listed in xorg.conf.
On my Mandriva system 2010.1 (cooker) evdev is loaded via the /etc/modprobe.preload

My keyboard, joystick and mouse are Logitech, EX110, and JS, extream 3d pro.
</edit>

I've just edited that file and commented evdev from being loaded.
dmesg still states it is loaded

The mouse and kb are using the ps2 inputs, the js is usb.
Any tips appreciated

Thank you, Glenn

Cool Solved

Hi, I found a solution.

After posting this thread, i did a google search, yeah, I know! should'a done that first.

I found 2 instances that were helpful, one LFS and another sidux.

Both mentioned evbug being set in the kernel as a module (In my case) or set statically in the kernel debugging section.

I didn't realise I had this set, Must be a default.

So, I blacklisted the module evbug, and the messages are gone!

ref:http://sidux.com/PNphpBB2-viewtopic-t-3168.html
http://linuxfromscratch.org/pipermai...ry/032401.html


Thank you to all (28) who had a look.

When I next configure and compile a kernel, I'll fix it properly then.

Thank you, Regards Glenn
