I am not sure what options were in effect there. As far as I can tell the acpi_backlight option alone did not work with Thinkpads. While it would prevent the generic interface with "vendor" the thinkpad-acpi driver looks at the ACPI variables directly (the same that the ACPI video driver uses to tell there is generic support) and without the option to thinkpad-acpi brightness control still would not work. In the cases before, there was no pausing when the generic interface was active, so the thinkpad-acpi option alone was enough. Why there could be those effects described by Alex, I cannot really tell. There is a comment in the acpi-driver code that sounds a bit like querying the abilities might have an effect in the ACPI subsystem. But still, it sounds a bit strange. > > Attached.

Do I understand correctly that Jaunty always worked correctly in your case? -- the brightness applet and function key do not work on my thinkpad x61s https://bugs.launchpad.net/bugs/324061 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
