Ubuntu 11.10 – Problems with screen flickering

Posted in forum, install, workaround with tags , on November 8, 2011 by jb

Since 9.10 I have had very few issues, Ubuntu has worked well on my Samsung NC10. However, the new (2.6.39+) samsung_laptop kernel module causes serious backlight flickering and makes the desktop unusable. Bug report. This bug occurs when the laptop is running on battery power only.

Luckily Voria has a PPA repository that solves a variety of Samsung Ubuntu problems. Instructions on how to use the repository and apply a backlight fix can be found here. Although these instructions are for a previous version of Ubuntu they work fine for 11.10. It does say that if you are using BIOS 11CA then the backlight fix is not needed. However, this is not the case, the fix is needed and works fine. Thank you Voria!

I recommend that all Samsung Ubuntu users look at Voria’s forum.

Anyhow, now that the flickering has stopped I’m enjoying using Ubuntu on my NC10 again.

Progress on Unresolved Issues (1)

Posted in forum, unresolved with tags , on December 15, 2008 by jb

1. Hard drive – Excessive load cycling?

Unfortunately, there is now some evidence which suggests that using Ubuntu may reduce hard drive life due to excessive load cycling. However since this is not a new problem for Ubuntu laptop users, an appropriate solution probably already exists.

There is now a forum thread discussing the load cycling problem. The original blog post with useful comments should also be read.

2. Touchpad

The NC10’s touchpad does not work well using Ubuntu. Although some progress has been made on resolving some of the reported problems with the touchpad, this is still an annoying problem.

The original blog post outlines some touchpad problems. There is a useful forum thread on the topic.

3. Hotkeys

A number of workarounds for adjusting brightness have been discussed at length on this blog.

Considerable progress has now been reported on this forum thread which discusses the root of the hotkey problem.

Jon Bradbury has made some changes to the forum layout in an attempt to improve usability / utility. I would like to thank him for helping me out.

It would be great if issues could be discussed in the forum before they are added as workarounds / tricks / tweaks on the NC10 Ubuntu help page. It is essential that the information on this page is accurate and avoids speculative ideas that should be tried out by the community before being proposed as solutions.
