Calculator Button Configuration

[SteveRiley]

Yes, it would be best to start new threads. For #2, please provide sample screenshots of the affected sites. For #3, try this potential solution. If that doesn't work, feel free to start a new thread, and be sure to include details about your system.

This is probably not the correct thread, but what the hell. After many years away from kde I see three issues that do not exist with Ubuntu 12.04 Unity and Gnome 3.4:

1. The calculator button issue which has been discussed in this thread;

2. Distorted graphics on some websites only; and

3. I have Screensaver turned off in kde, yet after 5 minutes the screen turns black and then I'm screwed. It doesn't matter what I press, the desktop does not return and I need to do a hard 'turn off'.

These issues exist with KDE only. The power issue is the most important to me as it prohibits me from using KDE. I would be glad to create a new thread if necessary, please advise if I should do so.

Any thoughts would be appreciated!

Thanks for the tip John. Unfortunately, it didn't work. Strange.

I will find the answer to this.

Have you tried using the KDE menu editor? Apologies if you have, but my scan of the thread didn't see it.

Anyway, right click the K - Edit applications - Utilities - KCalc - Advanced tab shows the current shortcut key, and lets you set it. You must click Save for a change to be actioned. My Mail key now starts the calculator!

Well, I ran xev again and look what I got...


KeyRelease event, serial 36, synthetic NO, window 0x8800001,
root 0xd8, subw 0x0, time 2377228, (1523,39), root: (1525,62),
state 0x10, keycode 148 (keysym 0x1008ff1d, XF86Calculator), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False

Not sure what do next.

[SteveRiley]

I'm not really sure. I wonder whether the folks at the KDE forum might be more tuned into this? Try there...

I would hazard a guess that either KDE's Input Actions service or keyboard daemon are doing some kind of translation.

Any idea where you would check for or diagnose this?

[slopechz50]

I guess there is nothing to do to fix this, but I do appreciate everyone's help.

You could check if the calculator key is being detected by opening a Konsole window and running xev. (I think this command is installed by default.)

Then press the calculator key. In the output you should see data for the key event - I get

KeyPress event, serial 32, synthetic NO, window 0x9200001,
    root 0x15d, subw 0x0, time 123773980, (595,356), root:(599,418),
    state 0x0, keycode 148 (keysym 0x1008ff1d, [B]XF86Calculator[/B]), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 35, synthetic NO, window 0x9200001,
    root 0x15d, subw 0x0, time 123774096, (595,356), root:(599,418),
    state 0x0, keycode 148 (keysym 0x1008ff1d, [B]XF86Calculator[/B]), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

Well that explains it. There is no calculator detected when pressing Launch (1) key when running xev in Konsole.

[slopechz50]

It could be that the calculator key on your keyboard isn't being detected. I don't have a keyboard with extra keys, so I can't try it myself.

Regarding Kickoff's shortcut... Alt+F1 is already assigned. You can change that by right-clicking the "K" and opening the Application Launcher Settings window. Note that the Meta key is actuallya modifer, so you'll have to assign it along with something else, perhaps Meta+Space.

That works. Thanks!

I would hazard a guess that either KDE's Input Actions service or keyboard daemon are doing some kind of translation. For instance, my T520 has annoying "back" and "forward" buttons to the left and right of the up arrow key. While xev actually shows these as distinct keys, KDE sees them to be the equivalent to Alt+Left and Alt+Right.

Testing setting a custom shortcut - global - command/URL as you suggested, I find that I can set the calculator key (it shows as "Launch (1)" in the trigger - shortcut area) - but it does not have any effect. Other keys e.g. meta-shift-n do correctly call up kcalc.

I don't know why it's called "Launch (1)" ... nor whether this mis-match with what xev calls it may be something to do with the failure to launch.

Thanks for the answer. I don't understand why certain keys are not detected. I have tried every flavor of Linux under the sun with never a problem like this.
