Ubuntu-Certification

Please remove the certificate for L322X as the brightness control is not working with 12.04 LTS or 13.04

Asked by Jan T.

Brightness control is not working with the newest kernel of 12.04 LTS or 13.04. Installing the sputnik-kernel, which was developed together with Dell doesn't change anything.

Hello Jan,

This system that you mentioned here, Dell XPS 13 (L322X) [0], was only certified with "Enabled for Ubuntu"
Standard images of Ubuntu may not work at all on the system or may not work well.

I've also link this question to a known bug, there seems to be a solution in comment #91

Good luck!

Oh, BTW you mentioned that the sputnik-kernel does not work, this might be caused by the difference in hardware configuration between your system and the pre-installed one.

Can you help with this problem?
