Thanks Marwan for the detailed description of the bug. I just posted this as a fix for the users who were unable to change brightness, and I had no idea how deep the roots of this bug are.
In my case, both acpi_video0 and acpi_video1 do not work, i.e. the brightness does not change and the system is functional. When I use acpi_backlight=vendor things are different even if I disable nmi_watchdog . Are there any tests that I run? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1007765 Title: brightness adjusting crashes system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1007765/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
