However, if I issue 1 or 3 to /proc/acpi/sleep, when I try to resume the screen display does not come back. I am sure the system has resumed correctly though because when I do Ctrl-Alt-Del, the system displays all signs of going for restart and then restarts and I can ssh in. Do I have to issue a command on resume to bring back the display, and if so how? This happens in both console and XFree86. I have applied the relevant DSDT from the acpi website for the 4150, but it made no difference. Actually I did manage to get the screen to come back from a standby (not a suspend), but immediately after this I tried again and the display wouldn't come back. I tried unloading the radeon.o module, but it made no difference. The relevant log portion: ---------- PM: Preparing system for suspend Stopping tasks: =========================| hdc: start_power_step(step: 0) hdc: completing PM request, suspend hda: start_power_step(step: 0) hda: start_power_step(step: 1) hda: complete_power_step(step: 1, stat: 50, err: 0) hda: completing PM request, suspend PM: Entering state.
