Ah, that's a well-known problem and we cannot fix it without help of machine-specific code, e.g., drm1/drm2. Actually, both acpi_video and dpms try to restore video settings but nothing worked for Intel GPUs + LVDS + LCD panel AFAIK. > I think i915drm has code to specifically turn on the backlight as > I get some weird error message in the kernel console about a > timeout trying to turn the panel off during suspend when I'm in X. So, I guess it has an ordering issue. If my memory serves, drm1 was okay with vesa, however. I *think* it accidentally worked because of automatic VT-switching, which is still broken for KMS.
