The test was done as per your instructions, in the /sys/class/backlight /eeepc-wmi directory. This eeepc-wmi subdirectory exists with your patched kernel, but is not there with the older kernel. The test fails in the acpi_video0 and intel_backlight subdirectories, with both kernels.
There are no additional kernel parameters specified, here is the current boot line: XXX@XXX:~$ cat /proc/cmdline BOOT_IMAGE=/@/boot/vmlinuz-3.2.0-29-generic root=UUID=XXX ro rootflags=subvol=@ The video module is no longer blacklisted. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1000146 Title: [ASUS X101CH and 1015CX] the hotkey to turn on/off the display is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1000146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
