Why BackSpace is not mapped in other symbols used? For other keyboard, it is mapped in symbols/pc and symbols/us

All I can say for sure is if you install Fedora 11 and select the keyboard as
"Sun Microsystems : Sun Type 5/6" the backspace key does nothing.

xev shows that backpace in mapped to no symbol.

xkbcomp $DISPLAY shows:

    key <BKSP> {
        type= "CTRL+ALT",
        symbols[Group1]= [        NoSymbol, Terminate_Server ]
    };

With the attached patch to /usr/share/X11/xkb/symbols/srvr_ctrl, backpace works, and xkbcomp now shows:

    key <BKSP> {
        type= "CTRL+ALT",
        symbols[Group1]= [       BackSpace, Terminate_Server ]
    };

I will add

key <BKSP> {         [       BackSpace ] };

to symbols/sun_vndr/us(sunbasic)

Committed

Thanks for the right place to fix the problem!

Actually, two changes should be made -- include "srvr_ctr(xfree86)" does nothing to the final keymap other than force a "Terminate_Server" mapping, making the layout option "Key sequence to kill the X server" non-functional (kill server is defined no matter this option).

Sorry, I guess I was supposed to reopen -- current fix was incomplete, see previous comment. 

Thanks.

Using srvr_ctrl(xfree86) does not enable "kill X server" these days. There is separate xkb option terminats:ctrl_alt_bksp for that. So, I do not think we should comment out srvr_ctrl(xfree6).

The BKSP mapping is already added to that section. So, what else should I change in that file?

With Fedora 11, with the 'include "srvr_ctrl(xfree86)"' line present, then Ctrl Alt Bksp does kill the server, even thought the layout option for "kill x server" is not checked. 

If the line is commented out then the killing of the x server can be controlled by the layout option.

Doing a diff of the output from 'xkbcomp -a' with this line in and out indicates that the only contribution of srvr_ctrl(xfree86) is to add the "Terminate_Server" mapping, so it seemed safe to remove it.

I have used the two changes now for several days, and the keyboard works as expected. 

Maybe there is a difference between the keyboard package from Fedora 11 relative to the latest one?

Quite possible. I suspect, it is still using 1.6.

There should not be BKSP mapping in srvr_ctrl file. So in upstream, it is ok as it is. Please check in git
