Hibernate problem in 11.04

[Davin Gibb]

Binary package hint: hibernate

Hi all, trying to hibernate my netbook upon lid closing and am seeing two distinct issues;
- Computer trys to turn off, but immediately turns back on
- When it comes back on, I can see the left part of the netbook screen blanked out, and getting what looks to be scanlines. The right most part of the screen is ok, and i can actually use the mouse and gnome windows environment. I can even click the power button (in classic desktop) to power down the laptop (I know theres a dialogue box that pops up but its covered by the black box with scanlines, so I just press enter and the netbook proceeds to shut down)

I have played with the exact some HW in Ubuntu 10.10 and to get hibernate to work I had to do the below hack;

# sudo -s
# echo shutdown > /sys/power/disk

And then hibernate worked after selecting the event from Gnome Power Manager upon lid close. But in 11.04 I did the same, and this time the netbook actually turns off, but upon power back on, I still get the black box and scanlines. 10.10 did not have this.

This bug seems very similar to 771603.

Hi,

Same here on Lenovo S10-3 netbook. However, it appears that it resumes from hibernation after manually powering down the system a couple of times. I am using the final version of 11.04. The echo shutdown > /sys/power/disk didn't solve the issue. I believe there might be problems associated with restoring data from disk as this how hibernation normally work. Yes, hibernation is a very important feature that it's kind of how difficult a life is without it.

When I resume on hibernation on a netbook asus eeepc1005ha, the screen freezes at the 2/3 of the left part and I must restart. Hibernation works fine in previous 10.10.
