Ubuntu On Sony Vaio FW Series

10.10 with applet

egaistek — Fri, 11 Feb 2011 20:54:34 +0000

Who have problems with brightness fn keys in 10.10 ubuntu, please check if gnome brightness applet works for you (right click on gnome panel, add to panel, search brightness).

I see people still having problems with fw4x,fw5x models. I’m not much help here, because for me it just works now.

Upgraded to 10.10

egaistek — Mon, 29 Nov 2010 10:57:01 +0000

Upgraded today. Fglrx mixup with nvidia drivers again after upgrade, to fix I deleted nvidia-current package.
Brighness keys works great even with dual monitor setup. S1/AV Mode keyas are recognized. AV Mode runs player by default.

I guess sony broke again something in newer than mine models.

Plans for 10.10

Hello guys. I’m still on 10.04 where brightness works fine (except dual monitor setup). I see you say that in 10.10 they are broke keys again. I’ve not tried it yet just added in plans. Keep watching.

Brightness bug with dual display mode

egaistek — Wed, 04 Aug 2010 20:00:36 +0000

So I moved to Lucid. It was a pain to make fglrx work after upgrade. It somehow messed up with nvidia drivers and while Xorg was loading fglrx it was loading glx and dri extensions fron nvidia package. I fixed symlinks and installed fglrx 10.7.
Brighness control works ok while I’m on laptop without external display. But when I’m in dual display mode brightness control works only from power managmer. While using fn keys brightness popup doesn’t move.
Well, it’s time to fix a new bug.

Brightness solution for Lucid from Vanio

egaistek — Tue, 03 Aug 2010 09:59:36 +0000

As previous solution was not universal as I thought, many people confirm that solution from Vanio works for them. Try it.

While I’m finally moving to 10.04 I will test both solutions later.

Brightness fix for Lucid from Joe L

egaistek — Wed, 21 Jul 2010 04:04:43 +0000

As I have not moved to Lucid yet, not much played with brightness.

Then thanks to Joe L, I guess he found a universal brightness fix for Ati and radeon/hd drivers in Lucid. Read it, try it and report back how it works

Lucid brightness control progress

egaistek — Thu, 20 May 2010 07:17:18 +0000

I have spend some time on figuring out what’s broken in Lucid for brightness. It actually works through HAL and I can control it with python or shell scripts manually hooked to acpi events for Fn keys. But it’s a dirty hack.
So then I finally figured out that gnome-power-manager is responsible for osd notification of brightness control and for handling Fn brightness keys, and it is broken. It’s broken somehow partially because you can control brightness through power preferences (which is gnome-power-manager itself).
While I’m hacking a power manager the easiest way to control brightness is to add Brightness Applet on the gnome panel and control it with mouse scroll wheel.

P.S. I guess there is a way to add AV Mode key support without patching sony-laptop module.

What’s about latest Ubuntu 10.04 beta?

egaistek — Wed, 14 Apr 2010 19:31:09 +0000

I want to gather all problems for the latest beta in the one post. If someone have any problems with FW models in latest Ubuntu 10.04 beta, leave comments here then.
