on either knoppix or knoppix64 desktop=kde, the 'function-standby' key combination appears to do nothing, but 4 of these appear in dmesg:
[ 2455.368080] systemd-logind[2328]: New session c7 of user knoppix.
[ 2455.396021] systemd-logind[2328]: Failed to abandon scope session-c7.scope

There is no menu option for sleep/standby, 'lock screen' also does nothing.
If I 'kill' kded4 , then 'function-standby' works (see Gateway below)
-----
on LXDE, 'function-standby' works but when you hit the power button to wake it up, it will wake for a moment and then go back to sleep. hitting power the 2nd time will wake it up for good.
Also on LXDE if you click 'LXDE_Menu > Logout > Suspend' It appears to do nothing, but a segfault
appears in 'dmesg':
[24928.801250] lxsession-logou[10263]:
segfault at 14 ip 4c86ce1c sp bfdd3ca0 error 4 in libgio-2.0.so.0.4000.0[4c79c000+1ab000]

(knoppix desktop=kde)
On my Gateway 450rog laptop (Pentium M, Radeon RV200), using knoppix desktop=kde , the process 'kded4' seems to runaway continuously spitting out the following in dmesg:
[ 2455.368080] systemd-logind[2328]: New session c7 of user knoppix.
[ 2455.396021] systemd-logind[2328]: Failed to abandon scope session-c7.scope

The process 'kded4' is running away and eating memory

'function-standby' key combo doesn't work
if I 'kill' kded4 it will go into standby with 'function-standby', if you hit the power button to wake it up, it will wake for a moment and then go back to sleep, pressing power again wakes it up for good, but only the mouse pointer appears.
