Further information: I use the Keyboard (Cherry CyMotion Master Linux) in PS/2 mode on a docking station of an HP notebook. In "/usr/share/hal/fdi/information/30-keymap-hp.fdi" the scancode of the copy key (e00a) is mapped to "screenlock". In the same directory, mappings for several other computer manufacturers are provided.
And since gnome-screensaver listens on "screenlock" (which is identical to "coffee"), the screensaver is started when the "copy" key is pressed. I use the same keyboard on a different computer (non-HP) and there the behavior is not observed, since the manufacturer string does not match in "30-keymap-hp.fdi" and the scancode (e00a) is not set. This is not directly related to the Macally keyboard since it is connected by means of USB, but somehow on kernel level keycode 152 (KEY_COFFEE) is likely to be generated, which completely bypasses the X11 key handling. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/377175 Title: Volume Up button locks screen -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
