Comment 7 for bug 781556

Seems copy-pasting dropped the last 1 on the line, that should be

sudo bccmd psset -s 0x0000 0x028c 0x0001
sudo bccmd warmreset

Browsing through the bccmd source code: The first part is "put the value 0x0001 in ps key 0x028c and store it in store 0x0000". Store 0x0000 is the same as default, so the -s switch (specify store) doesn't really have much of an effect.

The following single command should work just as well (-r indicates do a warm reset afterwards)

sudo bccmd psset -r 0x028c 0x0001
