In my case (dell inspiron 6400/1505) the problem was not in the software but in the firmware.
I has to modify the dsdt of the bios of the laptop. The problem was because the bios was not sending the event of lid opened. Patching the DSDT, fixed the problem. To patch the dsdt of the bios, the acpi-dsdt must be applied to the kernel and the compiled dsdt must be added to the initrd. -- After closing the lid, video does not come back by pressing any key. https://bugs.launchpad.net/bugs/44393 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
