I have now come to a workaround that I am happy with. I still have acpi enabled, and I no longer get backlight resetting.
You can see the details here (which is of course for my Toshiba) http://docs.google.com/Doc?docid=dgd53r6d_36hqmmh4hn&hl=en Meanwhile, upstream says this bug is probably fixed in the coming xserver release, which I think means it will probably not be ported back to Ubuntu 8.04 Hardy. Debian Sid already shows better behaviour than Hardy on my Toshiba, although I only get four levels of backlight brightness from Sid. -- Starting up a virtual machine in a virtualbox changes the display brightness (again) https://bugs.launchpad.net/bugs/241195 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
