No idea which component actually causes this problem, but after installing Red Hat 7 Beta, if I type a ' (single quote) character, it doesn't show up on the screen until I hit some other key. If I want to type multiple single quotes in a row, I can't. Works fine in X11 terminals, just the Linux text console seems to have this problem. login prompt, bash prompt, pico, anywhere.
This looks like it's intentional (deadkeys feature): When you press ' followed by e, you should get the accented e character in some keyboard layouts. Which keyboard layout are you using? Some keyboard layouts have different keymaps with and without this feature (e.g. there's de-latin1 and de-latin1-nodeadkeys).
How do I find out/change the keyboard layout?
cat /etc/sysconfig/keyboard (or use "setup") I think "us-latin1" is meant to have deadkeys like that; perhaps you want "us".
Closing due to lack of user input
Sorry. Changing the keyboard layout to us from us-latin1 did indeed fix the problem, post install. What I was going to do (and never got around to) was reinstall Red Hat pinstripe and see whether this was sometime I originally screwed by switching to us-latin1 myself, or if the installer just picked us-latin1 instead of us for me.
