I'm facing a rather weird issue in the past few days after doing a clean install of Ubuntu Oneiric (w/ gnome-shell) on my recently-bought Asus U36SD.
I set up my keyboard shortcuts using System Settings > Keyboard > Shortcuts, and some of them get randomly reset.
Most of my shortcuts include the win key (otherwise listed in the keyboard shortcuts as Mod4), but those containing only Mod4 + get reset every two-three reboots.
For instance, Mod4 + T (for terminal), gets reset to the standard Ctrl + Alt + T, while Shift + Mod4 + W (for browser) doesn't (I've set up the latter with the Shift key, because it seems that Mod4 + W didn't get intercepted at all. Something similar goes for Mod4 + E for gedit, which only worked once or twice).
I have no idea if this is a Ubuntu specific issue, or it's related to gnome-shell or even with my current hardware.
Has this happened to any of you? If so, did you manage to fix it?
