Is there is any way I can further help to fix this issue? Do you need more information? This bug is related to this: https://bugzilla.kernel.org/show_bug.cgi?id=15513 This bug report on Launchapad describes the same sympthoms. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/573984/ Just wondering if this issue is still alive with all the latest kernel and driver updates. I cannot reproduce it on my arrandale machine. But I suspect that it is a ACPI issue, not a video driver one. If it is still reproducible, with the latest kernel, I could help you debug it further. Thank you for the help. I remember that I tried some kernel patching to have some limited support for brightness control. But I no longer have access to that computer. Should we mark this bug as closed? sounds like this one is lost to us now. |
