TightVNC problem with only one key (letter)

[Log in to get rid of this advertisement]
Mandriva 2008.1, while being an excellent release, introduced a new problem I've never seen before. The server PC has Mandriva 2008.1, client PC's have various different Linux distros and/or OS X.

VNC works otherwise perfectly, as expected, but one single key, the "m" letter has to be repeated everytime 2 times, so that VNC will actually accept the input.

Example: Let's try some foolish text that has M letters:

Code:
Mike's mother has a cat saying meow.
I just tried it and had to enter it like this to get the wanted text:

Code:
MMike's mmother has a cat saying mmeow.
Naturally, at first I suspected the M letter from the keyboard is broken. But after connecting the same PC from many different computers with different VNC client programs and versions, I came to the conclusion the problem can be nowhere else than in the server PC's (Mandriva 2008.1) tightvnc-server or configuration.

I have the Finnish keyboard layout at both ends. Environment variables seem to have no encodings set. Isn't this a totally weird problem?

If you have a file, ~/.inputrc, try renaming it to see if the problem goes away. You may have to start a new Xterm or logout/login.

If that's not it, maybe try this command to see if /etc/inputrc has been modified:
rpm -V setup

Those are the only two files I know of that might possibly do something like that.

Thanks for the tip. I restored /etc/inputrc (no .inputrc in my home folders) from the original packages. However, the MD5 sum was the same with my existing file, so it seems it hasn't been modified in any way.

Nevertheless, I still copied the file from the original package over my /etc/inputrc at both the client and the server PC and rebooted both. No luck, I still have to hit the "m" key twice to be able to enter it.

Any success on this issue? I am having the same problem. I have to hit the m key twice. Also, key repeating does not work for any key, except the 'm' key.

Its very odd.

Another thing you could try to scavenge for ideas is:
grep keycodes /etc/sysctl.conf

I got that idea by looking at /bin/setupcon, which is called from /etc/init.d/keyboard-setup.


Also, you never said if you are using a laptop or a desktop system. The script /etc/init.d/hotkey-setup seems to behave differently depending on what computer you have and if it's a laptop.

Question
I am connecting from a desktop when at home and from a laptop from work. Both behave the same.

I did have to do some funky stuff when I first installed TightVNC to even get it to work in the first place. Wish I could remember what that was. Anyway, I can't understand having a problem with just the 'm' key unless VNC is accepting as if its 'shift' or some other key like a combo key or something. But then I would expect it not to 'repeat' properly. But its the only repeating key.

/etc/init.d/hotkey-setup
All PC's are desktops.

grep returns no matches for string "keycodes" from /etc/sysctl.conf.

I have no "hotkey-setup" script in my /etc/init.d.

The problem still remains and I have absolutely no ideas how to fix it. Thanks for the help anyway, appreciated.

is your repeat broken on all but the m key like mine?

can you show your modules so we can compare

For me the repeat works for every key, like usual.

weird, here too
This bug is bugging e too.

s/e/me/


System: tightvnc-server on Mandriva 2008.1, x86-64, via java viewer or regular vncviewer, from other Linux systems or windows.

I had a look with xev (showing which events get through), here's what I got for typing the following keys: " m m k k "
(k just for comparison purposes, but space does the same)

Code:
KeyPress event, serial 29, synthetic NO, window 0x4200001,

    XFilterEvent returns: False

KeyPress event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345471231, (-552,630), root:(39,658),
    state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
    XLookupString gives 1 bytes: (20) " "
    XmbLookupString gives 1 bytes: (20) " "
    XFilterEvent returns: False

KeyRelease event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345471318, (-552,630), root:(39,658),
    state 0x0, keycode 65 (keysym 0x20, space), same_screen YES,
    XLookupString gives 1 bytes: (20) " "
    XFilterEvent returns: False
So a single keypress 'k' gives these x-events:
Code:
KeyPress event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345467703, (-552,630), root:(39,658),
    state 0x0, keycode 45 (keysym 0x6b, k), same_screen YES,
    XLookupString gives 1 bytes: (6b) "k"
    XmbLookupString gives 1 bytes: (6b) "k"
    XFilterEvent returns: False

KeyRelease event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345467807, (-552,630), root:(39,658),
    state 0x0, keycode 45 (keysym 0x6b, k), same_screen YES,
    XLookupString gives 1 bytes: (6b) "k"
    XFilterEvent returns: False
Whereas a single keypress 'm' will give either:
Code:
KeyPress event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345458327, (-552,630), root:(39,658),
    state 0x0, keycode 58 (keysym 0x6d, m), same_screen YES,
    XLookupString gives 1 bytes: (6d) "m"
    XmbLookupString gives 1 bytes: (6d) "m"
    XFilterEvent returns: False
or
Code:
KeyRelease event, serial 29, synthetic NO, window 0x4200001,
    root 0x44, subw 0x0, time 1345453022, (-552,630), root:(39,658),
    state 0x0, keycode 58 (keysym 0x6d, m), same_screen YES,
    XLookupString gives 1 bytes: (6d) "m"
    XFilterEvent returns: False
Upon careful examination, pressing 'm' will only trigger a _KeyPress_ event every other time.
As for how to solve this,...?
Bugreport I guess...

This can be fixed by starting the vncserver with "+kb" appended to the command:
vncserver :7 -dpi 80 -geometry 800x480 +kb

appending "+kb" works great for me, thanks
