Sending Shift key to Linuc

[revmike]

I'm using Remoter VNC over SSH tunnel to access a Centos 5 box running vncserver. I can't send any uppercase or shifted keys to the remote system.

I ran xev (X event viewer) to capture the keyboard events and this is what I saw...

Notice the sequence of events...

Shift key press
Shift key release!!!!
'd' key press
Shift key press!!!
'D' key release
Shift key release

When I compare the events from another VNC client (Chicken on Mac) I see the following (sane) event sequence.

Shift key press
'd' key press
'D' key release
Shift key release

Somehow extra events are getting pumped in, and it is fouling up my Linux sessions.

BTW the same events are generate when I use my bluetooth keyboard (ZaggMate) with the physical shift key, the bluetooth keyboard with the on-screen shift key, or the onscreen keyboard.
Also capslock does not work, though I haven't debugged the events there.

Any evaluation of this?

Hi revmike,
Sorry for not replying earlier. I did read you post originally. But I've been really swamped, and didn't get a chance to reply until now.
This problem is very interesting. I'm going to definitely be looking into it.
I've created a trac ticket to make sure this gets looked into:

Thank you for your report!,
Raf.

If this was happening when using caps lock on an external keyboard. Then it will be fixed in Remoter VNC 3.8.4 (Pro 1.2.4), which were sent to Apple for review earlier today.

Thanks!,
Raf.
