Package: xserver-xorg-input-evdev Version: 1:2.3.2-2 Severity: wishlist I have a PS2 to USB adapter. One connects a PS2 mouse, and a PS2 Keyboard to it. Then plugs it into a USB port on one's computer. The problem is X-windows never expected that I would only plug in a keyboard, or only plug in a mouse, to it. So it ends up Segmentation faulting. However if I unplug it from USB, restart X, then plug it back in, all is well. Or, before I start X, I must be sure both a keyboard and a mouse are plugged in, then all also will be well. So you should double check, and if you cannot get an address you want, you should not segfault, but instead merely leave a warning in the logs. Anyway, you already detected at least one working mouse and one working keyboard, so there is no reason to ruin the session just because some of the additional ones were not where you thought they were (without double checking, and instead segfaulting.) Here I only plug in a keyboard to the PS2 adapter, then start xdm. Segmentation fault.

Now i unplug my adapter, start xdm, then plug it back in. Everything works fine.

Now I put both mouse and keyboard onto the PS2 adapter and reboot. Fine again.
