OK, updated my SL-C860, the keyboard stuff seems to have changed a little.
I'm using Cacko 1.21b with Keyhelper enabled and previously I had this problem with the Shift key sticking if I used /. Now I get various other issues with either shift or Fn sticking. - I guess you still need to disable prior to running Xqt. (khctl disable).
Rootless mode seems no further on. Managed to get xlogo to display ONCE. There doesn't seem to be a good indication of what works and what doesn't in rootless mode.
Almost everything I try to start whilst in rootless mode ends up killing the server
