Comment 17 for bug 181057

I'm also using an Acer Extensa 5220 and I'm experiencing exactly the same problem as zombiepig does.
Besides, if i press delete, currently known as keycode 242, the wlan status indicator led toggles. That doesn't have any effect on the wlan module at all. I tested all available keys with xev and found out that the bluetooth key is also having keycode 242. That key shouldn't work at all because of the lack of a bluetooth module.
I also tested all generic and acer keyboard layouts. None of them revived my delete key. After studying man xmodmap I entered the "xmodmap -e "keycode 242 = Delete"" command which revives the key for the current session. Unfortunately the wlan status indicator led still toggles.

We might rename delete's keycode, but how to do that. I'm not having any further ideas for fixing that issue. Please fix that. :)
