Can I ask what the upstream status of these patches are? I just had to replace my (broken, and now out of production) 1558 with a new Arrandale laptop (a Dell L501X / "XPS 15"), and was amused to discover that it, too, needs the intel_backlight patch.
This has been a long-standing issue, spanning three Ubuntu versions (including Natty) and 7 kernel releases. It affects *many* machines, and given the crushing weight of the comments in this thread appears to have had very extensive testing. So what's the holdup? Why isn't this in mainline, or at the very least in Ubuntu's default kernel? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568611 Title: Screen brightness control fails on Dell Studio 1558 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
