Hello, I doesn't break anymore, with any installed kernel. However, when it was broken, the problem appeared with all the kernels in the list (I've tried them all), even with the kernels which were working well with brightness before the bug. -- [Jaunty] Brightness to minimum, cannot change (Lenovo 3000 C200) https://bugs.launchpad.net/bugs/317640 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 317640] Re: [Jaunty] Brightness to minimum, cannot change (Lenovo 3000 C200)
If you upgraded, you hould still have some older kernels installed. If
you boot and press "esc" you get into the boot menu ("grub") where you
can select older kernels. Start with 2.6.27-something, which is the
Ubuntu 8.10 Linux kernel, check if it works again, and if so, please
work your way upwards to the latest Jaunty kernel and check where it
breaks.
If even the Intrepid kernel does not work any more, then it is a
regression in a different component. In this case, can you please check
https://wiki.ubuntu.com/Hotkeys/Troubleshooting whether the brightness
keys produce a proper keyboard event? (you should see it in "xev"
already).

[Bug 317640] Re: [Jaunty] Brightness to minimum, cannot change (Lenovo 3000 C200)
Hello, I've updated my system one hour ago, but the problem is still there and it really affects the laptop usability, I cannot read anything when there is even low sunlight. As there are still no fixes, I decided to try some workarounds. There is more information. All the following commands are done as root. dbus-send --system --print-reply --dest=org.freedesktop.Hal \ /org/freedesktop/Hal/devices/acpi_lcd \ org.freedesktop.Hal.Device.LaptopPanel.SetBrightness \ int32:2 returns : Error org.freedesktop.DBus.Error.UnknownMethod: Method "SetBrightness" with signature "i" on interface "org.freedesktop.Hal.Device.LaptopPanel" doesn't exist Killing hald and launching it as follows : /usr/sbin/hald --daemon=no --verbose=yes shows, when trying to change brightness : 18:11:38.964 [D] hald_dbus.c:3197: udi=/org/freedesktop/Hal/devices/computer_logicaldev_input_0 [12229]: 18:11:38.966 [D] addon-acpi.c:201: event is 'video LCD 0086 ...but the brightness still stays minimal. echo 3 > /proc/acpi/video/GFX0/LCD/brightness bash: echo: write error: Invalid argument cat /proc/acpi/video/GFX0/LCD/brightness The folder /sys/class/backlight/ is empty. I've also tried omnibook, as some people suggest when facing similar problems, but it doesn't work too. Brightness-applet dispays a tooltip saying "Cannot get laptop panel brightness" and, when launched with debugging, says that power-manager says that the brightness is not supported on my laptop. It's sad because brightness worked correctly with previous releases of ubuntu and even with jaunty, relatively, at the beginning. Everything works perfectly under Windows XP. I don't know what to add. I've tried all the stuff I know. The bug is still there. Please tell me if you need any more information. -- [Jaunty] Brightness to minimum, cannot change (Lenovo 3000 C200) https://bugs.launchpad.net/bugs/317640 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

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please attach your X server configuration file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.0.log) to the bug report as individual uncompressed file attachments using the "Attachment:" box below. Could you please also try to run without any /etc/X11/xorg.conf and let Xorg autodetect your display and video card? Please also attach the /var/log/Xorg.0.log from this attempt. Thanks in advance.
