I've had a question on a Portuguese forum and a bug report on bugzilla regarding a few issues with Samsung and backlight. Disabling 'Dim when idle' does fix the issue (alongside with a grub entry: acpi_backlight=vendor).
I'm sure probably some people have run against this, and I've found some sources on github (Greg KH). I haven't checked the license of them, but... what would be the best way to grab a fix for this users (even if it's from an external repository)... For what I could found out, two things are needed:
- samsung-backlight - samsung-tools.
Anyone knows where's upstream for this so I can dig up a bit more... My google searches were somehow confusing and innefective.
The upstream, in-kernel driver, should handle all of this for them without any changes needed. Have them try the latest kernel, and if that doesn't work, please file a bug upstream with bugzilla.kernel.org and for the platform driver, and it should be resolved.
Note, there was a lot of work done on this driver recently, so it might have to wait until the 3.3 kernel is released for it to work properly for this specific laptop, as a bunch of new devices just got supported this development cycle.
hope this helps,
