thanks for the info. It looks like I'm using the same graphics card as well. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Hey there, Thanks for the response. It is good to know that this is not a debian specific issue. * As for my graphics card, I am using an ATI chip. This is a fairly old PowerBook G4. * Kernel Version: 2.16.18.4-powerpc I will definitely try to do a bit more research about the backlight curve issue.

Re: PowerBook G4 screen in Debian not as bright as Mac OS X or OpenBSD
Hi Amit, I'm not sure what the graphics card is in your powerbook, but I noticed a reduction in brightness compared to OSX when using Debian on my iMac G5 (revA) which has an nvidia device. When I put the question to this list, this is the response I got back: On Sun, Dec 10, 2006 at 03:03:29PM +1300, Torrance wrote: 4) Screen too dim. The default backlight brightness in Debian is noticably dimmer than in MacOS X. So far, we have not been able to work out how to fix this. What kind of graphics chip do you have? You should be able to upload a new backlight curve if you're using Linux 2.6.18 or higher. Also, for NVidia chips, we haven't yet found out for sure how to detect the maximum value allowed (I was the one rewriting the backlight infrastructure in 2.6.18). Hence it might be that, when using an NVidia chipset, the display is not that bright as in Mac OS X. And anyway, this is in no way distribution specific. Greets, Michael Unfortunately, I had no idea how to play with the brightness curve so I had to stick with the brightness I was given. Torrance GnuPG / PGP Encrypted mail welcome.

Re: PowerBook G4 screen in Debian not as bright as Mac OS X or OpenBSD
Thank you! I did check out pommed and it requires kernel 2.6.22 I think so I will have to compile that and then compile pommed from source. I rather not move into unstable just yet.

Thank you for all your help! I guess I'll live with this. I will try reading some more on this issue. Thank's again Amit -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

I use powerprefs 0.8.0 and pbbuttonsd 0.8.1.

The changes in the new releases are mainly aimed at the new Intel based MacBooks. I think also the new versions won't fix your brightness problem because it does nothing else as Yves-Alexis wrote in his email. Nevertheless you might want to give it a try. > Also, I've read something about pommed package available in testing and > unstable. Do you have any experiences with that? Pommed is a small daemon created to support the Intel-based MacBooks. The latest version got also support for PowerBooks but the main focus is MacBook. It has only a subset of pbbuttonsd's features, but it does a good job. Nevertheless it won't fix your brightness problem because it uses the same methods to control the brightness as pbbuttonsd.

I checked out the 'max_brightness' and 'actual_brightness' and both of them are set to 127. Is it safe to set them up at a higher level?

If you have the sysfs interface with radeon card, you can try to look in /sys/class/backlight/radeonbl0/ Especially check for max_brightness and actual_brightness. If you want, you can manually adjust it using: echo 127 > /sys/class/backlight/radeonbl0/brightness Regards, -- Yves-Alexis -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I think your system uses the new SysFS Brightness interface which has 128 or maybe 256 brightness steps on your system. You could check this with the program Powerprefs, go to the display page (light bulb) and check which "Driver" is currently active in pbbuttonsd to control the display brightness. The programming of the graphics card's backlight controller is done by the kernel. There might be various reasons for setting the max brightness level as it is. Maybe the OpenBSD guys love to take higher risks regarding their hardware? Who knows ;-) You might want to ask this question on the kernel mailing list as well.

PowerBook G4 screen in Debian not as bright as Mac OS X or OpenBSD
Hey guys, I have Debian 'etch' installed on this system and my God it is a beautiful system. It gives life back into this old baby. No major issues at all. Great job by the developers! However, I have a small issue with the brightness level. I had OpenBSD (4.1) and Mac OS X (10.4) installed at one point and the brightness level was much higher than what I have here in Debian. I installed pbbuttonsd and brightness keys were working but still can't get it as bright as OpenBSD or OS X. Searching the ppc mailinglist suggest the use of ikeys to give 15 brightness levels? But checking aptitude it seems that this package is out of date and would conflict with the installed pbbuttonsd. Any suggestions? Any one have similar experiences? Thanks!
