Title: x11vnc not acceptingkeyboard input for some characters
Post by: b1ackmai1er on February 16, 2011, 08:24:14 AM

Hi, I am using X11VNC and dropbear on my TC 3.5 machine and connecting from windows XP using VNC.

Once I connect, I can type all letters A-Z but only lowercase letters a-f in any of the TC "windows" programs i.e. . However, in a terminal windows I can type any characters.

If i open a remote terminal window using putty then all works ok.

For some reason all the TC "windows" programs do not recognize letters "g..z"

Anyone got similar issues?

Hi I tried running X11VNC with the -dk command and the debug output shows that the lowercase keys g-z are being received by X11VNC on the TC machine but they do not seem to get sent to the TC windows programs.

Debug output for pressing letter m which does not get displayed in the VNC window:

What version of x11vnc is it?  On older versions you may need to supply the "-xkb" option to use XKEYBOARD for keystroke insertion guessing.  Newer versions of x11vnc should adapt automatically... If it does not for you let me know.

Hi, I am using the latest version from the repository - version 0.9.12. I believe all recent versions have -xkb on by default. I have tried this option as well as turning it off.

Thanks for your suggestion. Willing to try anything else you can suggest

Regards

OK.  That 'Mode_switch' looks really bad for typing an 'm' doesn't it...

Please try to restart as much as you can (X server, desktop) and then run with options "-xkb" and "-dk -dk" (twice) and collect the full output (-o log.txt is handy for this.) Then connect and type some characters that won't show up.  Then attach the full log to this thread or sent it to me some other way (PM, etc.) if you prefer.  You can annotate the log where the characters are not showing up.

I gave up on this version of vnc after spending many hours trying to get it to work. I now use x0vnc and although it's not perfect it's good enough for me.

Could this be the same or similar problem?

I use this extension quite a bit for vnc operations (I like the SSL features). I haven't seen this problem.

Edit:
This is the command that I use:

Code: [Select]

sudo x11vnc -norc -display WAIT:1024x768:0.0 -once -timeout 60 -unixpw tc -ssl TMP -sslnofail -nc -auth /home/tc/.Xauthority &

i had this problem. for me, it only happened in some windows, like the dillo or app browser. in aterm everything worked fine.

i fixed it by doing this:
http://www.tinycorelinux.com/faq.html#xmodmap

Code: [Select]

if the altgr symbols do not work in the browser or openoffice then modify the .xsession file by adding:

sleep 3 && xmodmap -e "clear Mod4" -e "add Mod5 = Mode_switch" &

Just before

exec "${DESKTOP:=jwm}"

Or, in later versions, right after waitforX.
