Andreas, please update the bug report with the output of uname -a
Also, please run the following commands and attach their output to the report, one attachment per command: sudo lspci -vv sudo lspci -vvn sudo dmidecode Please be sure to attach as there will be a lot of output. Also please be sure to run with sudo, as these commands require root access to get to the required information. It may also be useful to run lshal -m close the lid, get back to your session, then attach the output of the command. ** Changed in: acpi-support (Ubuntu) Status: Unconfirmed => Needs Info -- display remains blank after closing and re-opening the lid https://launchpad.net/bugs/83320 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
