Bug#636135: Confirmed, modesetting-specific

Human memory is so weak. After working around this in my previous 
install, I had already completely forgotten about the bug and just spent 
about an hour debugging it...

Re-applying the workaround worked, however the new kdmrc is very 
different and doesn't contain TerminateServer anymore, so I had to 
proceed as others said, adding "TerminateServer=true" in the [X-:*-Core] 
section (line 59).

I noticed that this only happens with modesetting. The problem does not 
happen when Linux is booted with radeon.modeset=0.
