Updated some time ago. Moved back to Unity from Gnome Shell (there was bugs in Unity in previous releases). Brightness and keys works correctly.
And some time ago I moved from fglrx drivers to open-source drivers. Now hd video works pretty good, no glitches in Unity compizing.
A while ago I did a hardware DIY upgrade, I added SSD to existing HDD, so I now have 2 drives installed. SSD for fast loading and slow apps like Java, Eclipse etc. Pretty fast now.
I will defenetly make a post about SSD+HDD upgrade with pictures in near feature =)
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 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.
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.
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.
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.
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 :)
