It seems a typical HP problem For me (NC6320) I check /proc/acpi/video/C083/DOS
I fixed this in 10.04 Lucid, by putting the following lines (both needed, in this order!) into /etc/rc.local echo 1 > /proc/acpi/video/C083/DOS echo 0 > /proc/acpi/video/C083/DOS However, after dist-upgrade to 12.04 this trick does not work anymore... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/89860 Title: /proc/acpi/button/lid/*/state always says "open" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/89860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
