[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken
The brightness keys in my vostro 1000 and Ubuntu 7.10 are completely dead. Before upgrading they keys behaviour was vey weird. I still don't know where is the problem, and I don't have any solution. I just can change the brightness manually using (*without* blacklisting video module). At least is a temporary solution to me: First, view all the possible levels in LCD brightness file: cat /proc/acpi/video/VGA/LCD/brightness choose one, say X level (for example 75), and echo 75 | sudo dd of=/proc/acpi/video/VGA/LCD/brightness Adding the option 'no_automatic_changes=0' doesn't works completely for me. It just let me push the brightness down (Fn+UP doesn't works) and only using a pure terminal (i.e. CTRL+ALT+F1). The brightness miniapplication (I don't know the exact name in english) doesn't works. The gnome-power-manager doesn't shows me any option to adjust the brightness.

The FN-up/down hotkeys for increasing and decreasing brightness won't work in Gutsy Beta for me. I also had this bug in a development version of Feisty and then it could be fixed by adding blacklist video to /etc/modprobe.d/blacklist. When the final was out, I didn't need to blacklist the video-module anymore. Now in Gutsy, since Tribe5 the FN-keys wont work anymore. I have all updates installed, even the Gutsy Beta livecd doesn't work with the FN-keys for brightness. DarkStarSword suggested the same solution again, to blacklist the video-module and it worked for me. I noticed that I can't change the brightness from the guidance-power-manager applet anymore since the video-module isn'nt loaded.

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken
I think that's correct for laptops with keys that only send a keypress event, but there're laptops who change brightness by hardware (probably by sending some signal to the BIOS). It's not desktop environment specific, since I can change brightness with hotkeys in grub menu, but not after the acpi video module is loaded. Probably, when gnome-power-manager (or its kde counterpart) is loaded, it gets the keypress and change brightness, but I don't see why shouldn't I be able to change brightness when g-p-m is not loaded, since I can do it when no OS is loaded. -- Inspiron 1420 LCD brightness keys broken https://bugs.launchpad.net/bugs/140782 You received this bug notification because you are a member of Kubuntu Team, which is a bug contact for kdebase in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
Re: [Bug 140782] Re: Inspiron 1420 LCD brightness keys broken
My thinking is that on these models we should just let the BIOS handle this, since it handles it very well, and doing it through userspace means: * We need to handle it in every environment - KDE, Gnome, pure console, X with no window manager, etc. * We need to make sure it's always responsive and users do not perceive any delay * We're essentially going to end up telling the BIOS to do exactly what it wanted to do in the first place since these models handle it through libsmbios (I believe the controls in ACPI use libsmbios anyway based on what I read in a pre-feisty bug report). The only reason I can think of for not trusting it to the BIOS is if we need to override it for some reason (software driven brightness profiles? BIOS already keeps them for battery vs. AC, and it should still be possible to do more sophisticated stuff without disabling this feature since we can still getset the brightness at any time). Just my 2c. Maybe there is a very good reason for not trusting the BIOS that I'm not seeing (Aside from because we can). -- Inspiron 1420 LCD brightness keys broken https://bugs.launchpad.net/bugs/140782 You received this bug notification because you are a member of Kubuntu Team, which is a bug contact for kdebase in ubuntu. -- kubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken
Agree with above. Before the update that broke my Fn brightness keys, software-driven brightness did work. kde-guidance-powermanager has a slider bar that controls brightness when connected to AC/battery, and those worked fine (and still do).

[Bug 140782] Re: Inspiron 1420 LCD brightness keys broken
@Matthew Garrett: The problem is that, when brightness max levels is more than 20, g-p-m use an increase/decrease step value of max_levels/20 (5%). So, in my case, acpi reports brigthness max levels=100, and possible brightness values are: 12 24 36 48 60 72 84 100. When I'm at 72, if I try to increase brightness using hotkeys, g-p-m tries to set brightness to 79, but it's not enough to get to the next brightness level.
