Time to start becoming a terminal master. You'll despise navigation of any other form afterward
Why would I use the terminal for navigation? I've only used it to install software and solve issues.

I love Xubuntu and all, but I need to come clean about something:
The installer is a complete dumpster file. It's trash. It simply doesn't work half the time.
I know that when I get a system gets installed, it'll be rock solid, but I don't see how I can recommend this shit... at least until amnesia kicks in, and I forget what a pain in the ass it was to install last time.
[ 2.739463] mei_me 0000:00:16.0: initialization failed.
[ 3.044955] EXT4-fs (sdb1): Unrecognized mount option x-gvfs-show or missing value
I'm guessing there's something wrong with the /etc/fstabMy Ubuntu 14.04 is not booting up at all.
I was trying to make one of the 3 TB hard drives to show up on left hand side menu via disk utility. Also it was not allowing me to add folders after it showed. Hence I rebooted the Operating system.
Unfortunately after rebooting it: I receive the following error and Ubuntu does not boot up at all. (Bio-Linux 8 - Ubuntu 14.04)
Code:[ 2.739463] mei_me 0000:00:16.0: initialization failed. [ 3.044955] EXT4-fs (sdb1): Unrecognized mount option x-gvfs-show or missing value
Ubuntu is not booting at all.
Any help will greatly be appreciated.

So look at that and see if the bad mount option is in there.
I'm not sure what you mean when you said "you are admin". If you're using Ubuntu, you're most likely not logging in root as that is disabled by default. So by default, you'd probably need root permissions to read or write.I went into recovery (last time it failed). This time it worked, I was able to skip the mount by having it on automatic Mount options to "On". Now I am able to access Ubuntu.
The problem that I am facing now is how do you are able to create new files, folders or anything in the new hard drive? The option is shaded right now, which is strange/interesting.
At the same time, I can make the new folders on the default OS partition which is 20 GB.
EDIT: If I do it in terminal, I am told that I don't have permission, which is strange as I am admin.
PS: Its a brand new machine.
EDIT2: If I do sudo in terminal, it works, but not in Ubuntu itself. Strange.
I'm not sure what you mean when you said "you are admin". If you're using Ubuntu, you're most likely not logging in root as that is disabled by default. So by default, you'd probably need root permissions to read or write.
Do an ls -l on the mount location and see what permissions there are.
How are you mounting this drive?
EDIT there's nothing stopping you from doing a chmod to change the permissions. On phone, so you'll have to search for examples,but it's pretty easy.
I'm not familiar with Ubuntu tools. Do you run disk utility as Root? (did you have to type in a password to do something with it?)
Type mount in the terminal. That will show you the mount path of whatever you have mounted.
Then do ls -l on the mount directory to check out the permissions.
I am having a stupid issue with virtual box and installing xubuntu. I installed xubuntu and then openvswitch and mininet. When I power off the machine and turn it on again, virtual box asks me to install xubuntu again.
Anyone call help me? why the hell is it asking me to install xubuntu again and again?
Haven't used virtualbox, but if it's anything like VMware, you can opt to your (virtual) optical disc drives pointed at the disc or ISO of the install media. Maybe you've still got it set to look at that?
for initial installation I mounted the iso image for xubuntu and had the boot option from CD/DVD. should I unmount it after I install and reboot?
Try it, that sounds similar to what I was describing.

That seems fine.I ran Disk Utility via the GUI within Ubuntu.
I think I found what happened: its known bug in Ubuntu: http://askubuntu.com/questions/271516/is-there-a-program-to-mount-all-of-my-drives-automatically and https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1012081
would something like this work though:
sudo chmod 777 /media/1c1eba21-fc77-45f5-86f2-2c9fa22e0031
Thank you again for the help.
I have a question that has been bugging me with Ubuntu Linux.
What is the best option to have multiple Ubuntu user accounts access one workstation via the same network (school) and one that goes through internet (maybe on this option for now due to school IT department).
I know of teamviewer (over the internet) where one user can basically take over the workstation and use it like if they are there themselves. I have used it as well. The limit is that one person can use teamviewer to do everything and the workstation is not usable at that time.
I was wondering if there was a method to have multiple users to have GUI (Ubuntu) interface to access all the software that we are providing.
I have thought of using FreeNx, but I have not used in the past. What about any SSH options guys that could recommend?
The best would be multiple users using the same set of applications at the same time. Also them being able to save them in their respective folders.
The hierarchy that my mentor and I trying to establish is the following:
1) Admin - Mentor and I - we can see all work that being done
2) Users/Professors. - Standard users in Ubuntu
Also would recommend using what this video recommends:
1) http://www.youtube.com/watch?v=gFdBSyy4xcM for one users
2) Multiple users: https://www.youtube.com/watch?v=9gOMBFX8P9E
3) XDRP: https://www.youtube.com/watch?annot...&feature=iv&src_vid=gFdBSyy4xcM&v=sDZ6zmuYsho
Thank you in advance guys.
EDIT: Can do the same for folks who use Mac OSX laptops?
EDIT2: Thank you zoku88, I will try it on Monday.
EDIT3: Is there any tool to automatically distribute the number of threads (cores x 2) and amount of ram for each remote user or standard user? The admin will set the number resources available for the remote user or for the standard user. These resources will become available for the workstation after the user ends their remote session or logs off. Is there any resource management tool for Ubuntu Linux? Thank you in advance.
So you want them to all have separate accounts and access one system remotely? At first I wasn't sure if you were looking to have them all collaborate in one session (which I haven't done) but it seems like you just want to:
a) Create local accounts for your users on the workstation
and
b) Configure XRDP (and maybe SSH) along with possibly updating your iptables rules to allow for it.
Not sure based on your edits if this was all laid out for you already but hey, maybe it's helpful! Also not sure on the resource sharing edit 3 question but am curious to hear what you get back.

I think those are exact same thing.
They might even be symlinked? I forget
Anyway, question time:
1. If I were to do this, what would be a good distro to start with? I know next to nothing about Linux or using Terminal commands, so I want a distro that has a nice, easy to navigate GUI to fall back on. However the whole point of trying out Linux is to learn how to do things in Terminal, so I definitely want the ability to play around with that and customize the system to my liking.
2. What is the best way to learn how to use Terminal? When I was trying to install things yesterday I was literally just copy-pasting commands without knowing what they did, which is a fantastic way to execute commands that may end up completely wrecking my PC. I want to understand what I'm typing in rather than just relying on other people to supply me with these commands. How do I do that?

3. Other than being more flexible and lightweight than Windows, what is Linux's main appeal? Why do you guys prefer it to other OS'es?
Thanks. I was considering Ubuntu, since it's really popular, as well as Mint, since I've read it's beginner friendly. I don't think I'm ready to jump into a GUI-less environment just yet haha, but maybe I'll ease my way into it over time.
Man pages are interesting, I didn't realize that was a thing haha.
One more question: if I decide I don't like Linux, would I be able to "reclaim" that partition for Windows? Or will that partition forever remain separate until I reformat the entire hard drive and reinstall Windows?
I'm considering creating a partition on my new PC (I have a 1TB hard drive, so maybe allocating 50-100GB) on which I can play around with Linux and see how I like it.
CentOS is short for Community Enterprise Operating System. Since it still has 'enterprise' in the name, I probably wouldn't call it the consumer version. 'The free version' is probably more accurate. That said, if you want a system that never changes aside from getting security updates and bug-fixes, it's fine to use it even as a consumer. It'll last you a solid decade.1. I think Ubuntu is probably a safe choice for a distro to start with that has what you're looking for (a nice GUI plus you can still use the terminal). I personally use Red Hat Enterprise Linux at work and rely on the terminal daily, so if you want a less pretty, more established distro you can get CentOS which is the consumer version essentially of RHEL. Or Fedora. Those are all RPM based whereas Ubuntu is Debian based.
www.explainshell.com is a nice place to paste those commands. It's not perfect, and it basically just searches through man pages and presents them in a nice way, but I still like it as a first-step to understanding a complex command.2.

Package management. For most programs I can learn about its existance and install it from the command line in a few seconds. No searching google for a download link, or looking for legit download links on pages covered in ads. No clicking through 'next' in the installer. The vast majority of software is installed and updated with the same handful of commands.3. Other than being more flexible and lightweight than Windows, what is Linux's main appeal?

Your boss has to decide whether to revert to the original SLES, or to
switch to openSUSE 11.4, and then upgrade in about a month to 13.1, as
11.4 goes out of support.
You can not stay midway.
If you just inherited it I'd do a couple of things.
1) Do NOT let this issue linger
First of SP1 is really out of date, and that's really bad for a production machine in terms of security as well as bug fixes
Secondly the longer you wait the more it's on you to fix and less of an "inherited" problem.
2) Ask your boss or whomever if you can try and get a 2nd machine up and running in parallel and either just roll with Suse 12 since that hit a month ago or else switch to Debian/Ubuntu or RHEL/Cent depending upon your comfort and needs.
Then you can try and basically mirror the production machine before you do a switch out.
3) Quite franly with all of the SUSE buy outs I'd probably just ditch. Either way you can stay with this half backed machine. Just read the similar comments in that thread you linked.
Honestly you are probably gonna break SOMETHING, but the sooner you do break shit the less it'll be on you and the more it's just shitty management from whomever formerly ran this server.
So last night I tried to upgrade from Xubuntu 14.04 to 14.10. I used the update-manager, and it all seemed to go well. But when I rebooted, I got this:
I have no clue what went wrong there. I reinstalled 14.10 from USB, but same result. So I installed 14.04 again. Red error screen gone, but still didn't boot. I also noticed that the mouse no longer worked in the BIOS. I removed the motherboard battery and cleared the CMOS. BIOS was OK again, but still no boot. I ended up reinstalling 14.04 yet again, and that finally worked.
So now I'm basically back where I was, minus a bunch of modified configuration files.
Does anyone know what went wrong here and how I can fix that? The motherboard is an Asus Z97-A. I flashed a newer BIOS version a while back, but 14.04 doesn't seem to have a problem with that.
Is there a reason you don't want to disable secure boot or have you already done that?Bumping this because I would like to upgrade but don't want to run into this Secure Boot Violation again.
Also, is there (or has there ever been) a Linux gaming thread?
Is there a reason you don't want to disable secure boot or have you already done that?
OS's break. Ubuntu is known for having some quirky bugs every release.No reason other than I didn't know I could. When I googled the error message I mostly just found answers referring to dual-boot systems, which doesn't help.
I just checked the BIOS, and it doesn't seem to have the option to simply disable Secure Boot, but there is an option to change the 'OS Type' from 'Windows UEFI mode' to 'Other OS'. I guess I could give that a try, sounds like it basically disables secure boot.
I'm still puzzled though that it works with 14.04 but not with 14.10. Should I have cleared the keys in BIOS?
