Some news : blacklisting the video driver (echo blacklist video | sudo tee -a /etc/modprobe.d/local) fixes the boot problem : the brightness of my LCD is maximal during the boot sequence.
But in fact it disable the brightness control : I can not control the brightness anymore in the gnome panel (no setting are available), and special key doesn't work anymore... The problem seems to be in the kernel (2-6-24-16) for me, since it works with kernel 2-6-22-14...(without any changes in modules or settings) -- LCD Brightness on Laptop Always Set Very Low at Boot https://bugs.launchpad.net/bugs/12637 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
