Acer Aspire One D255E - Intel N10 graphics: display partially garbled returning from hibernate/S4

[Peter Petrakis]

In testing my new netbook, I discovered that when I return from
S4 that 2/3 of the screen is black/garbled.

Description: Ubuntu Natty (development branch)
Release: 11.04

ppetraki@ppetraki-AOD255E:~$ apt-cache policy linux-image-generic
linux-image-generic:
  Installed: 2.6.38.8.22
  Candidate: 2.6.38.8.22
  Version table:
 *** 2.6.38.8.22 0
        500 http://us.archive.ubuntu.com/ubuntu/ natty/main amd64 Packages
        100 /var/lib/dpkg/status

Expectations:
To return from S4 with a fully functioning display

Actual Results:
A black/garbled imaged that covered 2/3 of the screen. The
system remained responsive.

Workarounds:
I discovered that if I cycle S3 while in this predicament, the
screen is restored. Note, I tried switching back and forth to
the virtual console without any success. Even the virtual
console was a mess.

A picture of the failure is attached

Attached are the dmesg logs when using xdiagnose with
- extra graphics debug messages
- display boot messages
- disable vesa framebuffer driver

enabled.

The problem persists

fwts batch test results attached, include a run of 250 consecutive S3 iterations.

Hi Peter, probably this bug is the same as bug 745304

Can you install kernel 2.6.38-9.43 from proposed updates and check this is solved with it?

[Peter Petrakis (peter-petrakis)]

@Herton:

You're right, the proposed kernel solves the problem.

add-apt-repository ppa:kernel-ppa/pre-propose
apt-get update
apt-get install linux-image-2.6.38-9-generic=2.6.38-9.43pre201105030903

reboot

fwts s4

power on

Screen is sane, system is responsive.

Well done.

[Herton R. Krzesinski (herton)]

nice, thanks for testing.
