SubjectLost keypresses [was Re: GGI and cli/sti in X]
Hi!

AFAIK (briefly looked at 3.1.2 sources), X does never cli() on linux.

Lost keypressess are definitely linux's design problem: As long as
X handle switch-out requests itself, it is going to be there.

Keys you press after Ctrl-Alt-F1 and before X realizes it needs
console switch are lost by design. I'm currently solving it by making
Alt-FX work even in raw mode (then race goes away.)

Q: Is making second set of keys (Ctrl-Alt-F1..F12) marked as 'console
switch even in raw mode' acceptable?

Also, until X use medium raw mode & kernel is modified, shift state
will be lost accross console switches. I'm thinking of forcing X into
medium raw, but it is hard...

Q: Do you think we can force X not to use full raw mode?
