Description Martin L ü c h e m 2010-02-18 07:44:38 UTC
The external monitor simply does not show anything. The internal monitor works but with the wrong resolution of the external one.

Regards, Martin

Will you please try the 2.6.33 kernel and do the following test? (Add the boot option of "drm.debug=0x04"
   1. dmesg >dmesg_before; intel_reg_dumper >reg_before; echo mem > /sys/power/state; dmesg >dmesg_after; intel_reg_dumper >reg_after
   2. Press the power button after the system enters the suspended state and then attach the output of "dmesg_before, reg_before, reg_after, dmesg_after"
