@rouble good point, thanks.

comment Several devices missing from lspci— why?
Try lspci -vnn. There have historically been WiFi chipsets (broadcom is an obnoxious example) which had only proprietary drivers that had to be wrenched out of Windows and jammed into Linux, but even those enumerated with lspci. Perhaps you've hit a new level of Windows lock-in games. I'd give Ubuntu 15.10 (even live-usb) a shot, as they seem to have beaten back more of the "Trusted Computing" crap.

comment File name encoding wrong in KDE, but correct in GTK/tty1/
You probably needed LANG=*.UTF-8 in the environment such as export LANG=en_US.UTF-8. Now can you tell me why StackExchange is giving me a four year old question (which I just noticed).

comment Is it possible to save Linux virtual console content and scrollback in a file?
Yes, since you can see it, it is somewhere. Unfortunately, that somewhere is the hardware frame buffer for the display. It would probably be easier to transcribe it by hand than rip it out of the display hardware.

comment messed up partitions during mint installation
"Can somebody help me out of this mess?" probably not, unfortunately. Although most everyone here has done something like that at least once, but we learned from it as I hope you will too. Make backups, make certain that you are asking the software to really do what you think you are. If in doubt, check first, then, check again. Always mount a scratch monkey (that story is from 1979, you are part of a long, glorious history in computerdom; presumably, you didn't kill any monkeys in the process).

comment Read a file line by line and if condition is met continue reading till next condition
This answer very nicely answers the question of "how do I cope with most of the issues of using read". Sometimes though, the OP needs to be unasked: using read for this task requires all your explanation and is manifestly the wrong tool for the job when half-line sed comment just works. (±0 if it matters).

comment Sort & organize a huge heap of photos
Pre-processing would be some batch process rejecting un-decodable images. I don't know of a tool off hand, but I could probably write it in 15 minutes, relying on jpeg libraries to tell me if they can't decode. As a batch process (one image, then the next, and so on) it could cope with 1.68M images in one folder. How much patience would you need? To be measured.

comment Sort & organize a huge heap of photos
shotwell will do exactly as you ask. You may need to pre-process if shotwell isn't happy with malformed images but that's another question.

comment Proper permissions on SFTP upload and download subdirectories in a user's home directory?
I'd learn AppArmor because that's the sort of thing it is intended for. SELinux is also worth mention, but I think there is a much higher ramp-up cost and you don't mention government agency approval as a need.

comment Troff Load User Font
I would strongly recommend looking at troff to LaTeX tools. Troff may not be a completely dead language, but it's heading there.

comment DNS temporarily fails with VPN addresses
Not having a live DNS server is not a solution. Open a new question. Over and out.

comment mv: No such file or directory error even though directory most certainly exists
The kernel and the filesystem(s) are not lying to you. You are mistaken about something that you haven't shown properly.

comment limitations of CUPS command line printing of image files
You have a belief that lpr is expected to transform files into the representation you want. SVG is text. My question is why the PNG file works at all.

comment DNS temporarily fails with VPN addresses
So edit the resolv.conf, expect it to be overwritten if dnsmasq is running. There are at least three ways that daemon could be started, which probably makes for a new question. The apt package dnsmasq-base contains no code that should auto-start it.

comment DNS temporarily fails with VPN addresses
The instructions for stopping dnsmasq above worked on an out-of-the-iso Lubuntu 15.10 (64bit) installation. The interesting question then becomes, is dnsmasq active? Check /etc/resolv.conf, nameserver should not be localhost.

comment DNS temporarily fails with VPN addresses
That's odd. Prior to the kill, I did ps -C dnsmsq to get the PID and strace -p PID to demonstrate to myself that it was doing nothing (and it wasn't). Could you do the same? I'll fire up a Lubuntu 15.10 and see if I can confirm.

comment Got a brand new laptop with hardware still unsupported. Should I wait or return it?
I've never heard such compatibility issues with a new box; it does look like a highly Windows specific build. Do you want to get stuff done or have a pretty box (for some definition of pretty)?. You can do far better, hit the same price/performance and skip the compatibility problems. I know what I'd do.

comment Does POSIX sh allow empty compound-list in first condition and empty condition in case conditional construct?
When a standard is at variance with every implementation you can think of, it is the specification that is wrong (it happens) or you've misinterpreted it. Sure, that's a semantic argument of "wrong", but practically, adhering to the spec just won't work.

comment Alsa not detecting the good sound card
It is possible that the on-board sound chip has broken; I've seen this happen. In the unhappiest version, it only breaks part of the way, so it is discoverable and yet doesn't work. About the best you can do in software is tell the kernel that the HDMI chip is in unaddressable memory with unreachable ports. If you are very lucky, you can find a physical jumper on the motherboard that disables the sound-chip. A more extreme way of saying the same thing is that your motherboard has partially failed and this can often lead to more severe failures.

comment How to declare some aliases dynamically in zsh?
I think the problem may be that variables set or exported in a script cannot alter the calling (parent) environment. See stackoverflow.com/questions/8604462/… for example.
