Description Jamie Kitson 2011-01-09 22:30:22 UTC
My Dell M101z with a Radeon HD 4225 fails to resume from suspend when my HDMI monitor is connected when I run s2ram. If the monitor is connected on resume I have to run xrandr a couple of times to get video on the monitor again. I also have to boot with the noapic option in order for resume to work at all.

Does 2.6.37 work any better?
Comment 2 Jamie Kitson 2011-01-09 23:14:24 UTC
No, same behaviour.
Comment 3 Alan 2013-12-11 11:57:35 UTC

Closing as obsolete, if this is still seen on modern kernels please update
