Moin!

echo -n 2 > /proc/acpi/sleep
-> present with the nice ascii printout that it sleeps, but
   it awakes immeditally.
echo -n 3 > /proc/acpi/sleep
-> works partly. System sleeps. But:
   --> After first sleep, everything is ok.
   --> After second sleep, the console is broken
       (many coloured blocks)
       X is still ok.
   --> After third and every following sleep:
      console broken (grey/coloured blocks)
      X broken (everything seems to be printed doubled like
      ll)

System:
   Compaq EVO N400C notebook
   Linux 2.6.12.3

Btw,
   o is there any tool to do sleep / a nice frontend to acpi
     for the console
   o where can I find the specification of ACPI sleep states?


Sincerly,

Nico

Are you sure your system support S2? (cat /proc/acpi/sleep)

Strange, see Doc*/power/video.txt, tell me what tricks you are using.

no.

ACPI spec from intel?
