Thunderbird, this value divided by 5 is for show the progressbar with the brightness. This progressbar works with value specified on list of laptops on /usr/share/hal/fdi/information/10freedesktop/10-sony-laptop- panel-mgmt-policy.fdi file, if you watch on it, you can see the reason, smartdimmer works with 100 value, this progressbar works in 20 value, here differences is 5 times. This "value=$((($value /5)-1))" is only a convertion for show the progressbar decreasing depending of the value of the brightness.
If you decrease 1 point of brightness with FN keys, you are using it, doing this: (100/5)-1= 19, 19*5=95, you are changing brightness to 95% and progressbar give value 19 from total of 20, for show you the progressbar with new nevel of brightness corresponding to it. You understand it better now? I don't understand for what reason you say that you preferred a whitelist of laptops, I think that people in HAL project, can help us for only detect the graphics cards affected more easily and more tiny and efficiently. You say: "It just doesn't mean that when a laptop uses lets say a geforce8 that it uses nvclock's smartdimmer will work, nor does it mean that all laptops from sony work." Of course, only laptopts with GeForce8/GeForce9/Quadro are affected with this problem (all? I don't know, but I think yes for this moment), not depending with here manufacturer. Only depend of if the laptop have a graphic card from this series. "For that reason I want to have a list. Perhaps there is some pattern in it or so. In the end I might find a better way based on e.g. the video bios." Is probably, that not alls are correctly detected with this method, but I thing that the whitelist can decrease more trying to reduce to graphical card detected, and adding support for laptops that don't work with this method. Reducing to a list that have this characteristics: - It use nvidia8,nvidia9 or quadro for nvclock - It's a laptop with graphic card manufactured by "nVidia Corporation", (implemente with this or video bios, ... I don't know the better way for this, but this is the important) For this moment, we now that it's really, you can confirm with the list on the description. That confirm that don't need a whitelist with ALL laptops with this graphic cards. -- No Screen Backlight Control; Notebooks (Vaio, Macbook, HP/Compaq, Samsung, Zepto et al.) with Nvidia Geforce8/Geforce9/Quadro series graphics https://bugs.launchpad.net/bugs/95444 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
