Hi, I have a backport 2.6.27.x custom kernel installed on my 11.0 system, running KDE 4.3. I've noticed that the Thinkpad (mine's R61/R61i) brightness control does not work through the keypad. I can change it through the Powerdevil battery manager. I have the right options put in for brightness control in /etc/modprobe.d/thinkpad_acpi. The dmesg output for thinkpad_acpi is :-

thinkpad_acpi: ThinkPad ACPI Extras v0.21 thinkpad_acpi: http://ibm-acpi.sf.net/ thinkpad_acpi: ThinkPad BIOS 7OET24WW (1.03 ), EC 7KHT22WW-1.06 thinkpad_acpi: Lenovo ThinkPad R61/R61i, model 8937A13 thinkpad_acpi: radio switch found; radios are enabled thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver thinkpad_acpi: Disabling thinkpad-acpi brightness events by default... Does acpi_backlight=vendor boot param help? This should change these lines in thinkpad_acpi output and let the thinkpad driver try to handle brightness instead of video.ko.

   Thomas Thomas, I'll have to append these lines to grub, at the bootloader...am I right? Yes or add it (once) at the graphical boot loader stage when booting.

Nope, it does not work :( There's another strange thing that happens though. I keep the power cord disconnected at bootup, and allow the KDE desktop to startup. Obviously, the brightness is set to a lower level- from Powerdevil. Now if I connect the cord the brightness should come back up all the way, right? Nope it does not go up. I have to either move the slider on Powerdevil to get it to a max level or disconnect the power cord again and reconnect it back. It now comes up all the way. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
