I've been a computer hobbyist since before the IBM PC, and a professional programmer not too long after that. I've had experience with electronic repair, manufacturing, and testing of professional audio.

I tutored other students in Fortran before PCs existed, built my first computer from bare circuit boards and reject parts (S-100 CP/M system), and transitioned from stereo repair, to professional audio manufacturing at Dolby Labs, where I set up the automated functional testing for Dolby professional equipment. From there, I went into programming full-time as a C programmer for Mac presentation graphics systems, then to Windows C++ video programming. My last 10 years was as a C++ Windows software engineer for a corporate source code control system.

I'm now a Linux user, doing part time website development using all open source tools like Vim, PHP, Javascript/jQuery, etc for local businesses. I'm semi-retired, so I only do jobs that I want to do.

comment problem entering my wifi password
Yes, it wants the password set in the router for wifi. If you don't know it, you can change it in the router setup, then you will need to remember it, and change it for any wireless device that might be connecting to it. This has nothing to do with Ubuntu.

comment How to clean-up/remove files in /dev/sda7?
OK, the dev/sda7 file looks right - the "b" means it's a device file (hence, yellow). FWIW, that is a single file that holds the unstructured data for the disk in a single block of bytes; mounting it adds structure (file system), to make it usable. As for the /home/d, I understand it is user "d", but I don't know what it means to be shown as output of df; My guess is it is an encrypted block mounted to become decrypted. I avoid encrypted blocks, so I don't know how to advise on what to do about it.

comment How to clean-up/remove files in /dev/sda7?
Yes, my point was that it was the only mounted partition, so it had to be the system. Unmounted partitions are not really important in this case. Also, I believe it is OK for you to actually change your answer and delete inaccurate information as discovered, rather than adding an addendum at the end.

The yellow text means it's a device file. I don't know who in their right mind would run chmod on this file, but I doubt that it screwed up your system. You basically made it executable; it should be rw-rw---- (660).

comment How to clean-up/remove files in /dev/sda7?
It looks to me like there is only one partition, and sda7 is the mounted OS. Did you see the output of the df command? I'm wondering what is the /home/d/.Private line from df. That doesn't look right.

comment How to clean-up/remove files in /dev/sda7?
Unless I'm sadly mistaken, I think this is not a good idea, and probably won't work at all. It seems to me that sda7 is his main system and only partition since df -H shows no other partitions.

comment USB Boot Drive is not recognized from Windows computers
If it's not formatted to ntfs or fat32, then Windows won't read it.

comment Where are key press scripts stored?
What makes you think it is a command? I don't know, but I would assume it's a constant (ie, an integer) passed on to the event handler. I'd guess you would need a way to trigger the event handler with those parameters.

comment How to save output to file that required root access
You are confusing the question by using inappropriate terms. current user is one user, root is a different user and has no dependency on any different user, so any user who knows the root password, or has sudo privileges can be root. The owner of the file (root) can assign permissions for anyone. The owner can be changed, too. Groups can be created for finer-tuned access. But it's not clear what you actually desire.

comment “error adding symbols: DSO missing from command line” while compiling g13-driver
My first idea is that you should format the error text so that it is readable - each line of compiler output should be separated. If you want someone to help, you need to do all you can to make it easier for them to do so.
