keyboard problems after 4.5.1
 
Hi,

...first of all - thank's a lot for providing these packages! Great job and no
package-related problems during the upgrade from 4.4.5.

there's just one thing which doesn't work after the uprade: my keyboard
behaves a bit strange now.

examples: the left- and up-arrow (separate arrow-keys, not num-pad) doesn't
work anymore (yes - right- and down-arrows work). The arrow-keys on the num-
pad work without problems.

AltGr stopped working, too and somehow I managed to change the keymap
completely (don't know how this happed, I didn't configure anything on purpose
- no normal characters worked, I only saw strange ascii-graph chars when
typing, in all applications kde/non-kde... - reboot helped).

Any hint on where to look for that? I tried already to adjust the keyboard
hardware and keymap, but it didn't help.

Thanks,

Andy

I have something similar happening to me recently, but in my case I
know for sure that it is not related to the kde 4.5.1 upgrade. Still I
think your issue might be the same.

Sometimes after waking up my notebook from sleep some keys stop
working. These include the arrow keys, but also my 'windows' key,
Home/End. Others I believe work. BTW they still work, but are detected
as different characters. Eg. down arrow key results in printscreen and
kscreenshot starts.

It _might_ be related to my upgrade to kernel 2.6.35.

Reboot always fixes this for me. If you haven't tried reboot, then I
suggest you try it now.
If your issue is something else, then sorry for the noise.

Regards,
Zsolt

I seen some issues, too, also prior to KDE 4.5.1 already. Some keys do not
work as expected. For example sometimes in Konsole the Return key does not
work.

Now with KDE 4.5.1 I had some problem in screen lock password dialog: It
fed keys of my password to the other widgets as well, as if I had pressed
Alt with seem. I was not able to unlock the desktop without killing the
locker process from a tty. I was not able to reproduce it so far.

Maybe thats some X.org issue? I still use X.org mouse and keyboard drivers
as I didn't figure how to do the udev / Linux Input thing statically. And
dynamically it didn't yet exact the results I wanted. I don't want mouse
clicks via touchpad for example. And I think also the keyboard layout was
wrong. Maybe own tweaks could be done more easily with xorg.conf.d but I
didn't yet look into it and still have my quite static in regard to input
devices X.org configuration file.

I am using some special 2.6.36-rc3 at the moment, but I had those keyboard
issue at times with 2.6.33 already. Sometimes they go away when I switch
to a TTY and then back to X.org. On other times I restarted X.

I never had any issues with the keyboard on a TTY tough, so I think its an
X.org issue.

I had this same problem when I didn't install a ktranslator dictionary
correctly. It also restarted kdm as I described in a Debian bug that I filed
recently. It took me a while to figure out the cause.

Hi,

...this is definitly not xorg-related. Keyboards works well in kdm during
login or when starting another window-manager (twm).

It must be something down in the kde config - but 'till now I'm unable to
locate the cause :(

Still looking for a solution, any hints welcome :(

I now had this also while typing a mail in KMail. Keyboard just didn't
work at all anymore. I switched to a tty and then back and then it worked
again.

I am sure I had those issues with KDE 4.4 already. I never bothered to do
anything about it, cause it was so unspecified. Thought could be anything,
and I was after finding the cause for some other problem in the last weeks:
random Radeon KMS related hard freezes for which now thankfully is at
least a work-around available.

Ciao,

I had the same problem with 4.4 (from sid). The cure was to delete the
.kde directory (or rather rename it and then try restoring the bits like
kmail.

With me it was so bad that I could not even switch sessions back to the
console.

The mouse worked, but from within KDE the keyboard was entirely
useless. On KDM it worked, and at that stage I could switch to the
console and the keyboard was fine there.

If anyone can tell me which .kde files might be relevant, I have the ones
that failed and can send them to whoever might be able to make sense
of them.

David

Hello,

Since a long time ago, Xorg switched to dynamic device detection
(hotplug, no xorg.conf, etc...). What happens with this is that most
input devices are now handled by the evdev driver instead of the old
keyboard/mouse drivers. Unfortunately, the keyboard mappings that
evdev does for keyboards are not compatible with the ones that the
older keyboard driver used.

Since kde does its own keyboard layout handling, you need to specify a
keyboard model at the same place where you choose the layout. All
models listed are meant to be used with the older keyboard driver, not
with evdev. Instead, there is a special "evdev-driven keyboard" entry
in the keyboard models list, which effectively lets evdev do its own
magic with the keyboard model and does not interfere with it.

So, to solve this problem all you need to do is to go to System
settings -> Input devices -> Keyboard -> Hardware and select "Generic
| evdev-driven keyboard" in the keyboard models list. An Xorg restart
may be needed for the changes to take effect (simply logout and press
Alt+E in kdm, then login again).

This problem and solution also applies to previous KDE versions.

Regards,
George

PS: If this used to work for you in 4.4 but not in 4.5, this is
probably because the keyboard layout module was completely rewritten
in 4.5, so it may not have upgraded its configuration correctly.
Indeed, I can see on my system that the listed keyboard model is
"Generic | Generic 104-key PC", which is not what I used to have in
4.4, however, for some reason it doesn't seem to apply this
configuration, so my evdev driven keyboard works fine.

keyboard problems after 4.5.1
 
Hi,

..thanks for all the hints I received. There was no final solution but I know
in which direction to search.

Additionally I found something on the web, which is very similar to my
problem:

http://bugs.gentoo.org/show_bug.cgi?id=153115

Unfortunately, the problem is not caused by xorg.conf. So it must be something
else.

I *have* at least a workaround:

bash# setxkbmap -keycodes 'evdev'

solves the problem and the keyboard works as expected. So I only need to know
where the wrong setting is coming from? Any further Ideas welcome and thanks
for all the hints!


rergards,


Andy

That's exactly what I'm talking about. That's what kde does when you
select "evdev-driven keyboard". But of course you also need to enable
kde's handling of keyboard layouts to apply this setting.
