Broken keys- Numpad Enter behaves like spacebar - Workaround posted

[kartagis]

Hi,

I would like to report that with revision: git-5475-g9a195de, Enter key on the numeric pad acts like spacebar, and Ctrl+W prints a literal W.

[ctrlaltca]

Can i ask your OS and Qt version please?

[kartagis]

Ubuntu 14.04 and Qt4

[ctrlaltca]

I suppose you mean ubuntu 14.10. It's known that ubuntu can have problems with qt applications shortcuts, due to the way they try to integrate them. The relevant bug should be: https://bugs.launchpad.net/appmenu-qt5/+bug/1380702
Afaik there are some known workarounds, but your mileage may vary.

[kartagis]

Should I upgrade to Qt5? And I mean Ubuntu 14.04

[kartagis]

lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.3 LTS Release: 14.04 Codename: trusty

[ctrlaltca]

Hum.. 14.04 shouldn't be affected by that bug; sorry.
Anyway,building with qt5 could be a good try; i suggest you not to use ubuntu's own version, but to attempt using a more recent qt version like this one: https://launchpad.net/~beineri/+archive/ubuntu/opt-qt541

[kartagis]

W: Failed to fetch http://ppa.launchpad.net/beineri/opt-qt541/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

Sorry, i linked a ppa for "precise" instead of the correct one for "trusty".
Please have a look at https://launchpad.net/~beineri for the correct ppa

This is Qt independent and its been happening for while, its not specific to the KVIrc version mentioned on report.

I compile, use Qt5 (5.2.1) and tested with Qt4 also, Ubuntu 14.04LTS and I can confirm this bug.
Any version in master for last few weeks no idea when this started happening.

[kartagis]

So, what's the next step? Just wait?

[wodim]

I'd wait until Ubuntu fixes it, honestly.

@kartagis If this is Ubuntu Bug should be reported to Ubuntu, Else you can wait forever here with this report.
Are you going to report it to them or find out f they have already such report? If it exists or you make a report, please link it here in your reply. Thanks.

Ill trust what wodim and ctrlaltca say and mark this as 3rd party.

I was investigating this because it bugs me also...

With xev command you are able to see a crucial difference between normal enter key and numbpad enter

Numbpad Enter

KeyRelease event, serial 37, synthetic NO, window 0x3800001,
    root 0x17b, subw 0x3800002, time 12012706, (38,47), root:(640,487),
    state 0x10, keycode 104 (keysym 0xff8d, KP_Enter), same_screen YES,
"   XLookupString gives 1 bytes: (0d) "
    XFilterEvent returns: False

Normal Enter

KeyRelease event, serial 37, synthetic NO, window 0x3800001,
    root 0x17b, subw 0x3800002, time 12008930, (38,47), root:(640,487),
    state 0x10, keycode 36 (keysym 0xff0d, Return), same_screen YES,
"   XLookupString gives 1 bytes: (0d) "
    XFilterEvent returns: False

So I think its a question (for a workaround) to remap (keysym 0xff8d, KP_Enter) to (keysym 0xff0d, Return)*

No idea how to fix that (properly) in Ubuntu and friends though

[kartagis]

Remap on Ubuntu? Will that not break existing functionality?

This is an HTML

[un1versal]

I ran this commad

xmodmap -e "keycode 104 = Return"

and now my Numbpad Enter Key under xev reports

KeyRelease event, serial 37, synthetic NO, window 0x3800001,
    root 0x17b, subw 0x0, time 15091454, (163,-15), root:(765,425),
    state 0x10, keycode 104 (keysym 0xff0d, Return), same_screen YES,
    XKeysymToKeycode returns keycode: 36
"   XLookupString gives 1 bytes: (0d) "
    XFilterEvent returns: False

And behaves like Enter Key does.

You going to have to redo this every time you reboot unless you make change permanent btw.
