What can I try now?
Excellent, that's a start. Can you use the 'intel_reg_dumper' tool (part of the xf86-video-intel driver tree) to capture register dumps from before and after the suspend/resume cycle? Now you should try the same thing, but with X running: <boot & login to your desktop env.> # chvt 1 (or ctl-alt-f1) <login as root> # echo mem > /sys/power/state <resume> # chvt 7 (or whatever your X VT # is) -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Pm-utils mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pm-utils
