If you are a programmer and got one of the OLPC foundation's G1G1 laptops, you may have noticed
that you are unable to use the key combination
Ctrl-S under the “Terminal” activity.
Sugar, the OLPC's GUI,
is to blame. If you switch from the GUI to vt1, by pressing
Ctrl-Alt-F2 (the little button where F2 should
be), you will get to a typical Linux terminal. Ctrl-S
works here, so what gives?
Apparently, Ctrl-S is special under Sugar. The way to enter
Ctrl-S in the Terminal is by pressing
Ctrl-Shift-S. This works, but is sort of annoying,
especially if you're an Emacs user. I haven't found a better way
around it while using Sugar, though.
My long-term solution is simply to switch to XFCE on my laptop. I may write that up once I'm sure it works.
