Bug Description

Binary package hint: xserver-xorg-input-evdev

When I am using evdev to control my (abnt2) keyboard (see the xorg.conf section in the end), X crashes randomly while I am typing (usually when I am typing fast). I have no problem with the traditional kbd driver.

I am using feity upgraded fro edgy a week ago and updated today. The version of xserver-xorg-input-evdev is 1:1.1.5-0ubuntu1

If I start X from the console I get the following error on the screen (I am copying by hand):

X: symbol lookup error: /usr/lib/xorg/modules/input/evdev_drv.so: undefined symbol: xf86OSRingBell

Let me know if you need any further information.

Paulo

I found an additional info on the net. It seems that upstream evdev driver do not call xf86OSRingBell anymore, see

I have the same problem with xserver-xorg-input-evdev 1.1.5-0ubuntu1 using feisty.

Xorg crashes when I run xkbbell. I get the same output:

Xorg: symbol lookup error: /usr/lib/xorg/modules/input//evdev_drv.so: undefined symbol: xf86OSRingBell

A "quick and dirty" fix:

Download the xserver-xorg-input-evdev source and comment line 245 of the source file named evdev_key.c (this is the line that calls xf86OFRingBell). Recompile and install.

Voila, X with evedev keyboards is rock solid again. Now I have my multi-terminal setup up and running again.

Of course this is not a proper fix, so I won't even put a patch here (unless the mantainer asks it, but it is so simple). I don't know the real implicataions of the change. But here X is running fine for the last 3 days.
