Laptop screen dimming problem (hardy)

[treb0r]

Hi All,

I upgraded to Hardy beta a few weeks ago after using Gutsy since release. I have a novatech rasor pro laptop (http://www.novatech.co.uk/novatech/s...e.html?NNB-600) and most things are working nicely.

The one major problem that I've found is that my screen now dims to the lowest setting on reboot, and I have to manually adjust it every time. To make things worse, the brightness function keys no longer work. None of this was a problem in gutsy.

The laptop has an intel core 2 duo cpu and Intel GMA X3100 Graphics.

I realise there are a few posts about similar issues on other laptops, but they all seem to be using different chipsets to mine.

Any help would be greatly appreciated.

i am having the same issue with an ASUS M50SV-A1 laptop, screen brightness is just too low to begin with, i tried using the nvidia panel after installing the drivers but it just don't work properly as the brightness is so low to begin with that adjusting brightness/contrast/gamma thru it does not work

Same problem,

Acer Aspire 5710
Moible Intel GraphicsMedia Accelerator 950 (256MB)
Hardy (Final release)


A problem I didn't have with 7.10

I had the same problem that is why I went back to 7.10... However, I talked to some people on the Ideapad thread and they say they don't have the problem but they are using the 32bit OS I use the 64bit and the launchpad bug report said it is a bug in the 64bit kernel. It is not just Ubuntu but a lot of Distro's and has been confirmed and is on the fix list and has been assigned to a developer.

Hi Chaps,

Well, as far as I know, I'm using the 32bit kernel.

I'm sure it is a kernel issue though, and I'm pleased to hear I'm not the only one seeing this.

Let's hope we get a fix soon. On a positive note, everything else seems just peachy - compiz is finally solid as a rock on this machine.

guys,

i have got a silly solution.

* set your screen saver activation time to minimum
* wait until your screen saver starts.
* wake your laptop up
* you will see your brightness just FINE.

its kinda weird. but it seems this is the only solution by now.

Hi Haseeb,

Ok, I'll check that out.

Still looking for a PROPER fix though

Just weighing in with yet another one it is happening on.

Mine happened after the Hardy Heron upgrade.

Dell Latitude D600

In addition to the screen dimming issue, mine makes a beautiful "pop" of "click" from the speakers randomly.

I see the brightness indicator coming and going all the time too. Crazy.

[smallerdemon]

Aw. It did NOT work for mine.

Oh well. Back to Gutsy Gibbon.

Here is what I found with my D600.

Hardy Heron changed and left permanent the on board BIOS brightness settings.

Battery was set to about 1/3 brightness.
AC was set to ZERO brightness.

Changing it in the BIOS did get me back to full screen brightness on reboot.

The constant clicking/popping noise, however, has yet to go away. Clearly something is going on in the background constantly. All system sounds are turned all.

We'll see how this goes and if the clicking/popping goes away. If not, then yes, back to Gutsy Gibbon.
