| Can you reccomend videos to learn server admin in centos? Posted: 04 May 2018 05:48 AM PDT I completed linux essentials on netacad last year which was quite easy to find video guides. This year I'm learning basic server administration but we are only given written learning material and I learn a lot better from videos. I was wondering if anyone had any recommendations on free videos to learn basic server admin for centos 6.9? I know I can get good material if I pay for a website like plural but being a full time student I dont have much spare money. [link] [comments]  |
| Time messed up with dual-boot of Win10x64 and Ubuntu18.04LTS UEFI Posted: 04 May 2018 08:25 AM PDT A day ago, I was successful in installing Ubuntu 18.04LTS (UEFI) onto my Lenovo laptop (7thGen i5, 8GB RAM, 1TB, split into 100GB for Linux and rest for Win). The installation is flawless, with one exception: The time displayed on booting up is wrong -- in both Ubuntu and Win10. In Ubuntu, the problem rectifies itself on connecting to the internet, while Win10 needs a little bit of prodding. It's not a major gripe for me, but I would like to know if there's any risk of future device failure associated with this, like a problem with the CMOS battery or something. Thanking you, Pakoda Economist [link] [comments]  |

| Xubuntu 18.04 near-fresh install stuck at login Posted: 04 May 2018 12:56 PM PDT Hi all, Sorry for the long post. Pulling my hair out a bit here. Recently installed Xubuntu 18.04 on my Thinkpad t430. Worked pretty much fine with minimal tweaking for about 2 weeks, though some packages behaved pretty differently to my 16.04 Ubuntu. After weeks of working fine now randomly I can't login, details are correct, but the screen just keeps coming back to login. Only graphical things I've done is install Cairo-dock + a wallpaper. Has anyone else had this? 1 - I'm able to login in through terminal, then when I try running startx makes the screen black for a second before coming back with "waiting for xserver to shutdown" - I can get it to start with sudo startx, but then the session is logged in as root not me. 2 - Tried chown on config files I traced, can't remember which now, think it was xorg. Others who have had the same error have done this with more success. It's the one that holds user credentials, and the suggested problem is that it is owned by root. EDIT - It was the .Xauthority file. 3 - Tried changing from lightdm to GDM3, which stopped me even opening the terminal, so had to plug my usb iso back in and run a repair, which did absolutely nothing apart from delete some programs, including cairo dock from what I've seen, so that can't be causing it. 4 - I've ran: sudo apt-get purge ubuntu-desktop sudo apt-get purge xorg* sudo apt-get purge x11* then sudo apt-get install xubuntu-desktop In hopes of cleaning it, no joy. 5 - Purged and reinstalled lightdm 6 - Added updated graphics drivers from: https://askubuntu.com/questions/980203/how-to-install-the-latest-intel-graphics-driver-in-ubuntu-17-10 "You can install Updated and Optimized Open Graphics Drivers from PPA repository: sudo add-apt-repository ppa:oibaf/graphics-drivers sudo apt update sudo apt upgrade -y" I'm absolutely, completely and utterly baffled. Been at this for hours, every solution I can find online that has worked for others hasn't worked for me. Apologies for any vagueness, I'll try and clarify what I can or add anything I've missed.

| No internet connection - Live Boot Arch/Anarchy Posted: 04 May 2018 06:04 AM PDT Hey guys. I've been having some problems recently. A month ago I've been trying few different Desktop Environments with Anarchy Linux. But after a few boots from pendrive a problem occurred. I couldn't boot Anarchy and have an access to internet anymore. When I was booting, I was getting this message: LINK, and after OS booted, I didn't have access to the internet. I tried using Arch, same thing. I didn't have much time to look into it back then, so I just decided to install Windows for a while. Recently I decided to try with Linux again. Surprisingly, my problem was gone, and I could install OS with no problems. But I need to reinstall it now (don't even ask) and my problem is back. It may not make sense, but it seems it happens only if I boot from pendrive few times, I'm not sure if I even have to install OS using it. And it fixes itself after a while of not live booting? I am making live boot pendrives using Rufus software, I usually choose an ISO option, and it used to work, but I also tried DD option. I tried few different ethernet cables. If you need some more information, let me now. [link] [comments]  |

| Install on MacBook Pro (from 2010) Posted: 04 May 2018 02:02 PM PDT Hi everyone I was so excited learning command line and stuff, but my laptop (with Linux Mint and Windows 10) was stolen from me at gun point ): My friend gave me her MacBook Pro, bought in 2010. 2,4 GHz Intel Core 2 Duo, 4GB RAM, NVIDIA GeForce 320M 256 MB. Is it easy to install Linux on it? I did it on Windows 10 with USB, so if that's how it's going to be, no problem. Also, this time I don't want to partition anything and just throw away the macOS... Is this crazy? Am I throwing away something good and valuable? Thank you! [link] [comments]  |

| I need help with a bootable USB Drive. Posted: 04 May 2018 10:36 AM PDT I previously duel-booted my old machine, and I liked it. I wanted to duel-boot my new one, so I used Rufus to make a bootable USB drive. When I boot with the USB drive, I boot into grub, and select "Try Without Installing" Some text appears 2 or 3 times for a split second, and then there is nothing but a black screen. I've tried multiple times. I know it's booting from the USB drive, but I have no idea what is causing this. [link] [comments]  |
| Posted: 04 May 2018 10:18 AM PDT I am trying to install stuff in this repo https://github.com/ruotianluo/pytorch-faster-rcnn Now, I need to compile some things so I need to use sudo sh make.sh This first lead to a problem "nvcc" not found, I fixed that by just including the full path of nvcc because I noticed that sudo nvcc lead to error "nvcc command not found" so I just added the full path of nvcc as /usr/local/cuda-8.0/nvcc which fixed that, but I have a problem in the next lines which does python build.py Problem is this requires sudo and doing sudo python anyscript.py will look for the directory in the secure list, how do I make it look for the libraries in my directory ?

| Do any file managers have the duration/length of audio and video files as a column header? Posted: 03 May 2018 11:25 PM PDT I've tried Nautilus, PCManFM and am currently using Dolphin, but none seem to support this by default. I tried googling for extra packages to install, but with limited success. edit: Dolphin seems to have it for audio files, but not video files [link] [comments]  |
| Dropped frames on 4K YouTube videos Posted: 04 May 2018 09:56 AM PDT My PC specs are the following:
The thing is I get dropped frames on 4K and 4K 60fps YouTube videos, no matter what distro, DE or NVIDIA proprietary drivers I use. I have also tried different web browsers: Firefox, Chromium and Chrome. On Windows, I was even able to watch 8K YouTube videos without any problem. I expect Linux to be at least as good as Windows, if not better, because it is. However, I know there are Linux users who have 4K monitors and I don't think they have any problems. EDIT: I have a 1080p monitor, so the issue doesn't really affect me negatively. [link] [comments]  |
| WhatsApp Desktop and Update Manager icons do not show on the panel Posted: 04 May 2018 12:03 AM PDT Linux Mint 18.3 Cinnamoon 64-Bit Cinnamon Version 3.6.7 Linux Kernel 4.10.0-38-generic I accidentally, somehow, have managed to remove the panel indicators of Whatsapp and Update Manager (notifying me of new messages and Updates). I tried reinstalling purging and reinstalling Whatsapp and looking in all settings and trying to add new applets, etc. to no avail With Update Manager I know there is a setting for "only show when updates available" but I have no now manually open Update Manager for updates, and I'm sometimes forgetful, so this is not convenient. Other than completely reinstalling everything (hard to do as I don't have an external HDD for backups) what are my options? [link] [comments]  |
| Easiest way to backup laptop on other laptop? Posted: 04 May 2018 08:42 AM PDT Basically I have an old laptop I want to use as a storage device/ backup server/nextcloud thingie/however you want to do it for my current laptop. Ideally I'd like this as simple, comprehenisve, and fullproof as possible. I know ubuntu's built in backup app can save to a nextcloud server and that looks pretty simply except i dont have internet in my apartment (i live right next to campus, usually just go over there). So whats the easiest way to do this? Link them together adhoc wifi style? something else? Please explain like Im an idiot noob, because I am Both are running ubuntu [link] [comments]  |
| Posted: 04 May 2018 08:30 AM PDT Hi, I'm planning on changing Budgie DE for i3wm, but I saw that the DE contains various utilities with it, including shortcuts, some of these utilities are very important. Will I will able to change these system settings without a DE?
Some of these are selected during the install, will uninstalling the DE break these, for example, will I continue to have to hability to configure networking and displays without Budgie DE? [link] [comments]  |

| network drivers dying after editing fstab...? Posted: 04 May 2018 03:44 AM PDT hi. i've been using the same realtek chipset (RTL8811AU) for wifi for ages now and although it has been working fine every time i've had to compile and install the module for it, today it just... died after showing a mate how to edit his fstab, and the thing is — it's not only me this has happened to...! ten minutes later he edits his fstab and reboots and his internet connection drops. i've resorted to phone tethering for the time being, and i wouldn't really consider myself a linux noob but i CANNOT wrap my head around this! i'm on debian stretch, if it helps. all i did to fstab was add my music partition, i haven't had this issue with fstab before either. i've gone as far as to recompile different drivers for my adapter, but modprobe doesn't seem to be doing anything productive as my network manager just stays idle. i cannot list networks with it either, so it's not blatantly just a connection issue. i apologise if i've left anything vital out. i am typing this on mobile!

| LDAP auth issues (x-post from /r/linux) Posted: 04 May 2018 02:54 AM PDT Morning all, I am in the middle of setting up a 2FA SFTP server for the company I work for. The stack I am going for is as follows: Bare metal install Ubuntu 16.04.4 OS OpenLDAP phpLDAPadmin KVM with Kimchi VM Ubuntu 16.04.4 OS Ldap client vsftpd duo 2fa using pam This is my first major go at getting this type of job done with Linux so learning as I go. Previous had a fairly successful Plex setup at home running on esxi using linux as OS but that was years ago. So far everything is up and running apart from the vsFTPd and duo 2fa auth. I have hit a stumbling block with the bare metal install in regards to openLDAP. Whilst the ldap server on it is running great and the VM client can authenticate fine and create a home directory etc, I can't set the bare metal os to authenticate to its own LDAP server. When I set up the ldap client utils on it, it will fail to boot properly, this doesn't happen on the VM client. My assumption is that when it starts, the LDAP server is not up and running yet so it can't connect and gets in a loop, does this sound right? What is the best approach to getting this running? Thanks [link] [comments]  |
| Posted: 04 May 2018 01:50 AM PDT Are there extra drivers I can/have to install to fully utilize my HDMI port? My partner has a Windows laptop and connecting it to a TV makes the TV act like a duplicate monitor and it channels sound to the TV as well. With my Mint laptop, it turns into a weird quasi-second monitor that also partially freezes the main monitor and doesn't transmit sound. [link] [comments]  |
| Posted: 03 May 2018 06:23 PM PDT I've read it's easier to move and extend volumes but I'm still a little bit lost. Can I get a breakdown and if possible in terms that are easier to understand so I grab the concept? I'd really appreciate it. I'm about to graduate college so I won't have to run Windows in my work laptop (Protected school WiFi doesn't support Linux for some reason...) and I want to use Linux at least 75% of the time [link] [comments]  |
| Facing some problems after installation Posted: 03 May 2018 05:47 PM PDT Hi, I've installed CentOS minimal on an old hp pavilion entertainment PC. First of all, it has an old broadcom card. So I'd have to install the proprietary driver to get started with the internet. Next, as it is a minimal install, I don't have DE. I'm quite familiar with arch and could figure out all post installation tasks myself so I chose to go down that road. Now, the problem is: during installation, while creating a user, I didn't chose to make the user an administrator (thinking that I can run whatever I want with sudo). After installation, I see that that my user is not in the sudoers file. So, I am left with a system where I don't have the root password configured. The only user I have is not an administrator and the user is not in the sudoers as well, so I can't run practically anything to install drivers from usb. (how to even mount usb without being root? how to create a directory in /mnt/ if I can't go root?) If somebody can specify a method to accomplish this, I'd be very grateful. Or else I'm planning to do clean install again and choosing to make the user an administrator this time (I've nothing to lose.. this was just for learning) EDIT: Sorry. A big mistake. Downvote me to hell please. I was under the impression that this was ubuntu and didn't even remember that I set a root password. Basically it was a password I use plus 'root' in the end. Panicked for no reason. Thanks /u/tanuki94 for pointing out. BDW, this still taught me something tho!. Thanks again. [link] [comments]  |
