vgaswitcheroo switching does not work; reported in syslog is the following:

Dec  7 17:40:53 vapulo kernel: [ 1268.734929] vga_switcheroo: client 0 refused 
switch
Dec  7 17:40:53 vapulo kernel: [ 1268.734935] vga_switcheroo: setting delayed 
switch to client 1

the "setting delayed switch to client 1" suggests that logging out; resetting 
X server (via e.g. Alt-E) and logging in again might work, but it doesn't (the 
internal Intel card - 00:02.0 - remains selected).
