I also have this problem on my HP nc8000. It works when I do "echo 0 >> /proc/acpi/video/*/DOS". I tried the above and disabled the hotkeys service and this also fixes it.
I have checked the lid state in /proc/acpi/button/lid/C153/state. When the DOS value is 1 the state does not change. It is always "open" When the DOS value is 0 the lid switch button works and it is reported correctly in /proc/acpi/button/lid/C153/state. I looked at the /etc/init.d/hotkey-setup script and I noticed in the function do_video () it does "echo -n 7 >$x;" for /proc/acpi/video/*/DOS. I remember when searching for a solution to this problem that some people had problems with the lid switch crashing their laptops and it was fixed by doing the above. I commented out those lines and now the lid switch works. It doesn't crash the laptop. Here is the bug report I mentioned: https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/157691 So it seems it fixes something for some and possibly breaks something else for others. -- No action when closing screen on HP 530 https://bugs.launchpad.net/bugs/277534 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
