    Oh ok, thanks. I tried the keypress and nothing happened.

    It definitely doesn't work OOB for me. I didn't know about vbetool
    before (I have messed with radeontool, though, when I told BenH about
    this problem a while ago).

    Here is what I ended up with in my lidbtn.sh (when I wish to
    sleep-to-mem):

    chvt 1 //vbetool needs to run from text console
    echo mem > /sys/power/state
    vbetool post //brings back video mode correctly
    chvt 7 //return to X

    This seems to work, if the framebuffer is not enabled.

    radeontool's regs argument provides some useful information, I think. I
    have attache three files, radeontool.pre, radeontool.post and
    radeontool.postpost, which capture the output of radeontool regs before
    the suspend, after the suspend and after the vbetool command
    respectively. As you can see, there is a significant difference between
    .pre and .post and less of one between .pre and .postpost.

    Perhaps also useful, I have attached the equivalent output with the fb
    enabled, in radeontool.fb.pre, radeontool.fb.post and
    radeontool.fb.postpost.

    Thanks,
    Nish
