comment Directory became UNIX binary (OS X)
If I had to guess, I'd say your home directory is an encrypted file and you changed something so that it either can't be decrypted or the OS does not want to decrypt it anymore.

comment utility to view qemu virtualized hardware
@Martin: It doesn't matter how your VM was createded, but it's true, that libvirtd must be running and that your hypervisor must be managed/manageable through it so that virsh can be used.

comment migrate all logical volumes (including swap and /) to a new disk
@Noosrep: if the "how" is not a problem anymore, then, yes, this should be quite possible. I did it once myself, but that was on a completely idle server. I don't know if there can be "unlucky" timings where things hit the fan when removing the old pv. To be safe I'd suggest you remount root as readonly, but it appears /var is on the root partition as well.

Please provide us the xorg.conf you use and the command you use to start X, and involved scripts, if there are any.

Then your task should be as easy as the second result when googling for "lvm online migration" tecmint.com/lvm-storage-migration

comment debian squeeze after end-of-life
Following up on your rant: are you willing to spend time and money keeping the old distribution sensible and working? If you are not, you have an answer. If you are, have you suggested it to the Debian project yet? How did they react?

comment migrate all logical volumes (including swap and /) to a new disk
Are you talking about a live migration while the server is up, running and doing work? Are there raid configurations involved? You don't have to move the swap partition. Just replace it with another one.

comment Mouse clicks stop working after random time, using Awesome WM + Gnome
(At least in its current form), you don't have to close random applications. The one you used right before the bug occurred and the one you were going to switch to, or the one you accidentally clicked are the most likely candidates. As the mouse virtually stops working when the bug occurs these windows should be fairly simple to identify.

comment BASH dd problem
Off Topic: Does this work? Can you just dd an iso onto e.g. /dev/cdrw and it will actually write data onto a CD-R and the result is a readable CD-ROM?

comment What exactly differentiates the root user from every other user?
Look up the source code of su. (For instance in the original archive of Debian's login package.) It's amazingly short. Yes, all the magic originates from UID == 0.

comment Blocking Websites by days and hours using Iptables in OpenWRT
@Delfin: You might want to consider sharing your iptables configuration. What it looks like before you try your "special" commands and afterwards.

comment Blocking Websites by days and hours using Iptables in OpenWRT
@Delfin: cron is used to schedule (and perform) the execution of programs and scripts. It cannot block Facebook. Therefore deciding to use cron or "crontab" is as useful as changing your keyboard layout. There is no one explicit command that will block Facebook. How you can use iptables to block Facebook depends on your iptables configuration. @gerhard_d. suggested using a proxy server. Maybe that is the better approach for you. I also said the ranking of rules is important not just the string it searches for. I think this is your problem, but without knowing your iptables settings idk.

comment Why cannot I ping 192.168.10.1, the default gateway, from an Ubuntu Linux 15.10 computer but I can do so from Windows 7?
@Frank: Hm, my initial idea was that you forgot to enable your interface, but that doesn't seem to be the problem. Can you show us the output of ip address show and ip route show, please? As mentioned by gerhard\ d., editing /etc/network/interfaces is not how things should be done on Ubuntu 15.10. Are you using the desktop or the server version?

Can the Ubuntu host ping the Windows host and vice versa? How did you put the network settings for your Ubuntu host? Obviously not using /etc/network/interfaces. Can you show us these settings? Also, open a terminal on the Ubuntu machine and show us the result of ip links show. Maybe we can help you with this additional information
