Version: 4.2.65 snapshot (using Devel) OS: Linux Installed from: Compiled sources I have a Dell Inspiron 1525 laptop, and with all the keyboard models that *do* in general work (including arrows, media keys, modifiers), the Delete key does not. xev does recognise it as Delete just fine. With Synergy, I can send the Delete stroke through to my other computer just fine. It just doesn’t work in any local app (including Firefox). However, KP_Delete (activated with Fn+. on this keyboard) does work. And additionally, the other day KDE didn’t find the kglobalshortcuts.desktop file so all of my global shortcuts stopped working. Why this is significant? Because then, my Delete key started working! I have looked into the rc files, and in fact my entire .kde4 directory, the only mention of Del regarding shortcuts is the Ctrl+Alt+Delete and the Ctrl+Alt+Shift+Delete for logging out (which I have disabled, and I set up the “windowsese” Launch Sysguard as Ctrl+Alt+Delete). So I feel there is a bug somewhere... :/
Closing this, it magically started to work at some point, could have been an odd constellation of X.org server, XKB, hardware and KDE, or just heck knows what.
