[natty] screen flickering upon resume from hibernate on 945GME

[Ярослав Почернин]

Binary package hint: xserver-xorg-video-intel

Screen starts flickering upon resume from hibernate on Toshiba NB100 (Ubuntu Certified) with Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03). It makes the whole system unusable. There were no problems in Maverick, so I may consider it a regression.

I have a Samsung N220 with a 945GME and have the same problem!

[Ярослав Почернин (yaroslav-pochernin)]

It seems like the bug only appears when the battery is charging (and that is 99% of cases when I resume from hibernate). Though I may be wrong. Last time I checked it with the battery fully charged, it resumed without problems. Gonna double-check it now.

[Ярослав Почернин (yaroslav-pochernin)]

Now it DOES appear even when the battery is charged. It was okay in beta 1 but broken again in beta 2.

[Bryce Harrington (bryce)]

Kernel issue most likely.

[Ярослав Почернин (yaroslav-pochernin)]

Can I provide any other information or maybe some logs? It's a really imporant bug.

[Michal Mlejnek (chaemil72)]

on the Eee 900A the same. beta 1 was OK but the beta 2 is affected.

[Emanuel K (capslock286)]

Altso affects Asus 1005HA

[Bert (bert-casula)]

Also for me on an Asus Eee Box B202 with 945GME graphics. No flickering or similar when the analogue VGA was in use, but just switched to DVI->HDMI connection and the flickering occurs on resume from S4. Have noticed also the following consistent behaviour:

Suspend to S4 -> Resume from S4 -> Flickering occurs -> Suspend to S3 -> Resume from S3 -> Flickering has gone away again

[least (least01)]

I can confirm the exactly same behavior as reported by Bert on my Samsung NC10!

kernel 2.6.38.9 solves the problem for me :)

[MattF (mat0)]

Same for me on NC10 - how do I get 2.6.38.9 kernel upgrade?

[least (least01)]

You have to enable the "natty-proposed" updates and upgrade/update your system!

[MattF (mat0)]

Thanks for that - managed to upgrade to 2.6.38.10 and fix the problem.

Ярослав Почернин:
several users have reported that the latest available natty kernel (2.6.38-10.46) has fixed this issue. Can you confirm?

[Ярослав Почернин (yaroslav-pochernin)]

Yes, seems like it works properly now!
