[gentoo-user] In X: <up> wants to "save screenshot". How do I stop this?

[Alan Mackenzie]

Hi, Gentoo!

Just this past hour, I've noticed that in Gnome 2, any depression of
<up> wants to create a .png image of my current desktop.  This is
regardless of which application is currently active.  This is
particularly irritating in Firefox, where I want <up> to scroll the
screen.

I suspect this might have been caused by a recent update to the ?event
library (I can't remember exactly what this was).

I hate it when people do "clever" things like this.  How can I make it
stop?

I would downgrade to previous version of the evdev driver and see if
it helps. Or disable/change the shortcut for print screen as a
temporary workaround.

You did me a huge favor by asking that question, thanks!  While poking
around in the keyboard settings applet I discovered a well-hidden option
to disable the Caps-Lock key.  I hit that stupid thing by accident at
least ten times/hour and say very vulgar things when it happens ;)

The keyboard-shortcuts applet does have an option to change the screenshot
hotkey, so maybe something changed it behind your back?

Could you amplify a little bit and reveal exactly what applet you used 
and where the little option is located?

I do
    emerge =dev-libs/libevent-2.0.16
and restart X windows.  Everything now works properly.  (The recently
emerged libevent was 2.0.18.)

I tried this (in Gnome 2) with System/Preferences/Keyboard
Shortcuts/Desktop/Take a screenshot.  It was set to <Print> and I left
it there.

Similarly, "Take a screenshot of a window" was set to <Alt+Print>.
Typing <Alt+up> triggered this.

I think there's something wrong with libevent-2.0.18.  Does anybody get
problems in KDE or XFCE?

No problems with KDE-4.8.3 and libevent-2.0.19 here

libevent-2.0.19 was merged here 5 May and libevent-2.0.18 on 26 Mar. In
all that time I never noticed anything strange with screenshots. So it
must be a gnome-specific bug

Nor here with KDE 4.8.1 and libevent 2.0.18.

Heh.  I told you it's well-hidden :)

This applies only to gnome2.  I've been looking for a similar
trick in gnome3 but it's even more hidden there and I'm still
hunting/hoping for it.

The System::Preferences menu has a "Keyboard" applet and also
a "Keyboard Shortcuts" applet.  The screenshot setting is in
"Keyboard Shortcuts" and the CapsLock settings are in
Keyboard::Layouts::Options...
