Same problem here with Ubuntu 10.04 on an Asus m51sn laptop. There seem to be quite a few duplicates of this bug (well I don't know which is the duplicate of which but this has been confirmed at least).
I'm not 100% sure, but these: 275902 480412 504998 seem all to describe the same problem or very similar. By the way as a workaround I unplug and replug the power adapter and brightness goes back to its normal value (the very moment I _un_plug it, it gets brighter, though not full brightness, as it goes to the brightness level of battery mode, which is brighter than the buggy dark of a resumed suspend state; then after replugging it gets back to full brightness) -- Screen Dimmed After Resume https://bugs.launchpad.net/bugs/409664 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
