Ubuntu should not wait for upstream. Try out the patch. It solves the brightness-notification issue.
1. Apply attached patch to hald 2. echo "options thinkpad_acpi hotkey=enable,0xfdffff" > /etc/modprobe.d/thinkpad_acpi.conf 3. Restart hal, reload thinkpad_acpi module => brightness notification works on Thinkpads, thus partly solving bug #357673. ** Summary changed: - Generic get_brightness function should read 'actual_brightness' not 'brightness' + [ThinkPads] No brightness-notification - Bug in generic get_brightness function ** Description changed: Binary package hint: hal Brightness notification always shows the same value for laptops with - hardwired brightness control, ex T42. + hardwired brightness control, ex T42. Thus not reflecting the true + brightness value. Problem is get_backlight () function in: hald/linux/addons/addon- generic-backlight.c Line 67 reads: g_snprintf (sysfs_path, sizeof (sysfs_path), "%s/brightness", path); should be: g_snprintf (sysfs_path, sizeof (sysfs_path), "%s/actual_brightness", path); 'actual_brightness' holds the current value of brightness. 'brightness' is used to set the brightness, and when read gives the last writen value! -- [ThinkPads] No brightness-notification - Bug in generic get_brightness function https://bugs.launchpad.net/bugs/372874 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
