The screen was so dim that I could barely see the outlines of the emacs and xpdf windows. Restarting xdm (and therefore the X server) didn't restore the brightness. But it probably is not a hardware problem, because rebooting the laptop restored the brightness to normal. -Sanjoy `Until lions have their historians, tales of the hunt shall always glorify the hunters.' --African Proverb -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
