Thanks for the suggestions, I will try setting the kernel command line. I found another solution that worked for me. With my nvidia driver enabled, I tried running the script from, http://www.thouret.co.uk/blog/2008/12/shell-script-for-linux-nvidia-kernel-module-laptop-brightness-workaround/
and it changes the brightness. Though it is temporary solution, gives me peace of mind till the issue is resolved! I can try creating another bug, but will that be classified as duplicate to this? -- Cannot change brightness with 2.6.27-11+ kernel https://bugs.launchpad.net/bugs/333386 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
