On my eeePC 901 running F-10 beta/rawhide with a US layout the keys with ~` (between ESC and F1) and "' usual spot near ENTER don't work. In gnome keyboard preferences the keyobard model is "evdev managed keyboard" and the layout listed is "USA International (with dead keys).
I have also discovered that it has the truly annoying issue that when you type apostrophe and the a letter you get accented characters. like this should be apostrophe s -> ś ŕ ẃ but when you type a space afterwards the char it seems to work '
This is standard behaviour of the US (intl) keyboard. If you don't need the deadkey features, just switch to normal US layout and the apostrophe and tilde key will work as expected again.
FYI: in US(intl), the tilde key produces a grave accent and the ~ sign on shift. the apostrophe key produces an acute accent, and a double acute on shift.
Thanks, fixed the problem perfectly. No idea why I selected that on install this time. Never have before!
