 Posted: Fri Mar 27, 2015 9:38 pm Post subject: Zooming via [Ctrl]+[=] broke |
 |
|
Usually, [Ctrl]+[-] zooms out and [Ctrl]+[=] zooms in (on an US keyboard layout). This works in most applications that support zooming (Firefox, Chromium, gedit, etc).
I've messed with some keyboard settings recently, and now [Ctrl]+[=] is broken. Instead, I have to use [Ctrl]+[Shift]+[=]. I can kinda see why, because + is generated with [Shift]+[=], but zooming was always an exception here!
This problem persists across all applications. It is extremely annoying, but I don't know what caused this change. Google does not reveal anything either (try googling for +, good luck  )
Does anyone have any ideas? |

I tracked the source of the problem down. I have two keyboard layouts defined in Xfce's keyboard settings, US and DE. I can switch them via a key combination.
If the DE layout defines the nodeadkeys variant, [Ctrl]+[=] zooming breaks WHEN THE US LAYOUT IS ACTIVE. It remains broken until I log out, removing the DE layout during runtime does not help.
Curiously, if the DE layout defines no variant, this problem does not occur.

Does this sound like a Xorg bug? |

There is a nice little app to show X events, called xev, maybe it can help you further.
Just
and run

| it sometimes is [Ctrl]+[-] and [Ctrl]+[+]. In such a case numpad or [Ctrl]+[Shift]+[=] might work. |

I had a look. Pressing [Ctrl]+[=] when:

The difference is that under the broken condition, the [=] key press is never received. Instead there are FocusOut/FocusIn events. Is the window temporarily losing focus? How come? |

Today I did a system update due to the new multilib system, and I got the following message:
| Code: | * Messages for package x11-libs/libXi-1.7.4:
* Some special keys and keyboard layouts may stop working.
* To fix them, recompile xorg-server.
|
Maybe It can explain it, have you tried recompile the xorg-server? |
