Screen remains blank after sleep on HP netbook, i945GME video chipset

[Erich]

Description: Ubuntu 12.04.4 LTS
Release: 12.04

HP mini netbook, 2GB RAM, atom processor

from dmesg:
[ 0.087839] smpboot: CPU0: Intel(R) Atom(TM) CPU N280 @ 1.66GHz (fam: 06, model: 1c, stepping: 02)

[ 1.299784] Linux agpgart interface v0.103

[ 1.300539] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000

Obviously, this is not an nvidia driver issue already mentioned on launchpad.

This seems to be related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1283938

I can successfully ftp, telnet or SSH to the netbook after I try to wake it, but the screen refuses to turn on.

It also seems to recognise new USB devices that are plugged in while the screen remains blank.

Ctrl-Alt-f1 allowed me to login and type (without seeing the typed text)
shutdown -r now
at which point the netbook restarted, and everything I was doing was gone.

I recently installed cpulimit to address the ongoing xapian index retrieval resource hogging bug mentioned here,

https://bugs.launchpad.net/ubuntu/+source/apt-xapian-index/+bug/830333

but after that I installed a bunch of updates that were due through the update manager, including the latest kernel.

For now, I have told the power manager to not sleep the screen.

Cheers,

Erich
