Bug#625211: linux-image-2.6.32-5-amd64: Can no longer control backlight
Package: src:linux Version: 3.9.8-1 Followup-For: Bug #625211 No, with the radeon driver it works, sorry for not having checked that. There is already a bug open against fglrx-driver, as brightness is concerned: 719536. The problem remains that one need to specify the kernel attribute in the grub configuration file, it would be nice if that could be handled during installation. Thanks, Carlo. -- Package-specific info: ** Version: Linux version 3.9-1-amd64 (debian-kernel@lists.debian.org) (gcc version 4.7.3 (Debian 4.7.3-5) ) #1 SMP Debian 3.9.8-1 ** Command line: BOOT_IMAGE=/boot/vmlinuz-3.9-1-amd64 root=UUID=221d4a92-44de-42bf-a8c4-1d8844595fbf ro acpi_backlight=vendor acpi_backlight=vendor ** Tainted: PO (4097) * Proprietary module has been loaded. * Out-of-tree module has been loaded. ** Kernel log: [5.657439] psmouse serio1: elantech: Synaptics capabilities query result 0x08, 0x14, 0x0c.

Bug#625211: linux-image-2.6.32-5-amd64: Can no longer control backlight
Package: src:linux Version: 3.9.8-1 Followup-For: Bug #625211 Dear Maintainer, there still problems related to backlight. At first I could not control it at all. Then, following forums and wikis on the net i tries to pass the acpi_backlight=vendor parameter to the kernel, and know it work... a little bit. What works is that all methods, the keyboard special keys, xbacklight, gnome- control-center, all udpate the same file, in my case /sys/class/backlight/samsung/brightness. But. First that file is reset to the maximum value at every restart. I worked around this by echoing something into it in /etc/rc.local. Second, and worst, when I change the file value at runtime (by any of the above methods), the value is applied... sometimes. I mean, I keep changing the value and once in while the brightness changes, after 2, 5, 10 seconds, and I have to be lucky that it happens at the right brightness. If you just change the value without keeping trying, the value is not usually applied. Regards, Carlo. -- Package-specific info: ** Version: Linux version 3.9-1-amd64 (debian-kernel@lists.debian.org) (gcc version 4.7.3 (Debian 4.7.3-5) ) #1 SMP Debian 3.9.8-1 ** Command line: BOOT_IMAGE=/boot/vmlinuz-3.9-1-amd64 root=UUID=221d4a92-44de-42bf-a8c4-1d8844595fbf ro acpi_backlight=vendor acpi_backlight=vendor ** Tainted: PO (4097) * Proprietary module has been loaded. * Out-of-tree module has been loaded. ** Kernel log: [6.554681] usb usb2: New USB device found, idVendor=1d6b, idProduct=0002 [6.554754] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [6.554841] usb usb2: Product: EHCI Host Controller [6.554910] usb usb2: Manufacturer: Linux 3.9-1-amd64 ehci_hcd [6.554991] usb usb2: SerialNumber: :00:1d.0 [6.558299] hub 2-0:1.0: USB hub found [6.558449] hub 2-0:1.0: 2 ports detected [6.588429] psmouse serio1: elantech: assuming hardware version 2 (with firmware version 0x040215) [6.621518] psmouse serio1: elantech: Synaptics capabilities query result 0x08, 0x14, 0x0c.
