OK. What's happened is that the VT combination has shifted from
<CMD>-<CNTL>-Fx to <ALT>-<CNTL>-Fx ... all OK now. (the config was correct)

yep. it does.

OK. It isn't by default (which was catching me out)
Shouldn't it be enabled by default if the kernel is built CONFIG_SYSRQ?
Additionally, like VT-switching, the modifier key appears to have changed to
<ALT> from <CMD>...
SysRq doesn't appear to have _exactly_ the same behaviour as before (but
this may be a consequence of the change of Xserver - no longer using
The SysRq messages no longer break through onto the screen (I did get them
on VT-1 at one point - but couldn't reproduce it).
- and once you've got into SysRq mode it appears to be 'sticky' - i.e.
commands accepted with a single keypress until you do SysRq again. Hmmm.
It might have been like that before - and I never noticed - because I always
The issue of a "GoodWay" (tm) to support Laptops with SysRq remains - I'd
like to be able to use it on my Lombard...
So, now the correct place to make changes to get the right symbols out for
~/` ±/§ and so on is in /usr/X11R6/..../xkb/symbols/gb - I assume.
I guess that I must have missed a place to look for the changes that
occurred to the modifier keys etc.... perhaps Kaoru should add this
information to his ftp directory. If people who monitor the -dev list don't
know, what chance have Users got ;-?
anyway, thanks for the help - I'm now the proud owner of a nicely
accelerated, non-flickering, ati mach64 XF4 installation.... *and* know
which keys to press ;-))
next time I have some time - I'll do the Lombard & the 9600 (imstt could be
BTW: It runs MoL (almost fine) too.
