Hi peeps, I've got an update. I'm able to change the brightness now inside X (running gnome). Running Ubuntu Jaunty and having the latest official nvidia drivers installed, you can set the brightness with the utility `nvclock` (got v0.8-Beta4). All you have do do is nvclock -S VALUE Where VALUE is between 15 and 100 or a delta like +10 or -10 Greetings! PS: Anyone knows an applet program (for GNOME) where you can set a custom command to change the brightness. or even a brigthness applet that has support for nvclock adjustments? -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

[Bug 146710] Re: backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M)
Same issue with Samsung q45 with Nvidia GForce 8400M. (nvidia proprietary driver) I found that the cvs (!) version of nvclock (http://www.linuxhardware.org/nvclock/) supports brightness change. I just followed instructions there to get the cvs version, compiled it, copied nvclock to /usr/bin and now 'nvclock -S 15' .. 'nvclock -S 100' work perfectly. Then I made a workaround which makes hal to change brightness through nvclock. For this I modified '/usr/lib/scripts/linux/hal-system-lcd-set-brightness-linux' and '/usr/lib/scripts/linux/hal-system-lcd-get-brightness-linux'. I don't know the *correct* way to do this. Now I can change brightness using gnome's Power Manager Brightness Applet. However when I press Fn-Up/Fn-Down it works like the corresponding key code gets emitted repeatedly, so the keyboard freezes until I press Alt-Ctrl-F1 and Alt-Ctrl-F7. It looks similar to what is discussed here: https://bugs.launchpad.net/bugs/212800 and I am going to try to downgrade bios - may be it fixes the problem. ** Attachment added: hal-system-lcd-set-brightness-linux http://launchpadlibrarian.net/20859843/hal-system-lcd-set-brightness-linux -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

The backlight keys (fn+up/dwn), the wlan switch (fn+f9) and the brightness function keys (fn+f5/f6) as well generate unknown key events and have not the intended effect. Writing to /proc/acpi/video/NVID/LCD/brightness under X has no effect (see SonniesEdge). However, this works outside of X (e.g. ctrl+alt+f1 terminal). This is obviously a bug in the NVIDIA driver, as with the default unaccelerated driver, this problem does not occur. The NVIDIA driver somehow blocks changes to the proc location from having any effect. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

Bugger, looks like we're completely dependent on NVIDIA releasing a binary driver. :-( Ho hum. In the meantime there are a few useful scripts on the thread mentioned above that can be used to change the screen brightness (by exiting to a terminal, inserting values in proc and then returning to X). As a result I've got a couple in my home dir called (imaginatively) low.sh and high.sh.

I've been experiencing this problem on my R60 Aura T5250 Deeloy ever since I updated from BIOS 01YI (WLAN, Backlight and Brightness not working anymore). These keys work when one is in the BIOS setup and only get disabled when the system is booting in ACPI mode. On Windows, Samsung has a tool called Easy Display Manager (on the Samsung CD and also available online) which takes over the control of these settings. So this stuff does not work on Windows either, because Samsung has disabled that recently and supplies this tool only for Windows (speaking with the tech support does help to understand the problem). So, in case these keys work for you in the BIOS and work with this Easy Display Manager, you have the exact same problem as I have. In case anyone has the original 01YI BIOS - please contact me, maybe there is a way to downgrade. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

I tried setting keycodes (after sourcing . /usr/share/hotkey-setup/key-constants) in /etc/rc.local): setkeycodes e002$KEY_VIDEOOUT # Fn-F4 External VGA toggle setkeycodes e004$KEY_LIGHT # Fn-F5 Backlight toggle setkeycodes e008$KEY_BRIGHTNESSUP # Fn-- LCD Brightness up setkeycodes e009$KEY_BRIGHTNESSDOWN # Fn-- LCD Brightness down When I run lshal -m, I see that the keycodes are correctly mapped, but the hotkeys still do nothing. Also, switching from battery to power does not seem to change my screen brightness, and the Gnome brightness applet does not work either. I have the same problems whether using the nVidia or Xorg driver, so I would suspect problems with the ACPI configuration: cat /proc/acpi/video/NVID/LCD/brightness outputs levels: 10 30 40 50 60 70 80 100 current: 0 cat /proc/acpi/video/NVID/LCD/state outputs state: 0x1f query: 0x00 sudo echo 10 /proc/acpi/video/NVID/LCD/brightness gives me a permission denied error, even though the proc file seems writable for root, and adding xhost + (just in case) does not seem to change a thing. I did not find any Samsung-ACPI module, so I wonder if the generic ACPI handling works for this machine. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

Same problems here with a SAMSUNG R700-Aura. FN-KEys to change the brightness doesn't work, also the backlight toggle (on/off) does not work. neither in x, nor in a console screen. see attachement: lspci -vv (same in gutsy/ 7.10, also with latest official nvidia drivers.) ** Attachment added: lspci_samsung_r700_aura.txt http://launchpadlibrarian.net/12808585/lspci_samsung_r700_aura.txt -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 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

I'm experiencing this problem on my Dell Inspiron 1520 with Intel and nVidia 8400 too. I've used Envy to update to the latest driver from nVidia and the problem still exists. I ran for a long time without restricted driver and the problem existed then too. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I think it is not related to the nvidia driver since disabling it does not solve the problem. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Same problems here... if I boot with acpi on, I can change brightness only using the nvidia-settings. Other hotkeys work fine (Fn sound up/down for example, or switch on off wireless). I have the flickering with all gl applications so maybe its related to the nvidia driver. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

My Samsung P35 laptop worked good with Ubuntu Feisty 7.04. Now I've upgraded my working Ubuntu to the recently published Ubuntu 7.10. In a few seconds after log in my laptop stops to react to Fn+LightUp Fn-LightDown key combinations. Even worse: the screen starts to flicker badly several minutes. I see instantly the backlight adjustment mini-window. cat /proc/acpi/video/VGA/LCD/brightness not supported Laptop became almost unusable, flickering makes me crazy. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Forgot to mention the flickering of the display like in the post before. Very funny thing: If I got to the console (STRG+ALT+F1) I can use echo -n VALUE /proc/acpi/video/NVID/LCD/brightness to change the display backlight brightness (this change only affects X if I did /etc/init.d/gdm stop before this) -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
