I have just rebooted with kernel parameter video.use_bios_initial_backlight=0 and it does not behave differently from the default boot parameters.
So... I think I've finished following all of the steps in https://wiki.ubuntu.com/Kernel/Debugging/Backlight - I don't have a Thinkpad. - I checked and I am not using the thinkpad_acpi kernel module. Let me know if there is anything else I can do to debug. In particular, I would like to test a brightness applet as mentioned on that page but I cannot located it. Any idea what package it would be in or where I would find it? ** Package changed: xorg (Ubuntu) => xserver-xorg-video-intel (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1214148 Title: Intel video: Display backlight cannot be changed on Toshiba Portege Z935 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1214148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
