I don't play games on Linux, but when I'm programming I'll have lots of Chrome tabs, text editors/IDEs, terminals, etc. across three workspaces, plus a music player and some other crap, and this all runs just fine on 4 GB. Lots of people seem to be able to play games and have Chrome tabs open at the same time with 8 GB on Windows, so unless WINE is using a lot more RAM I can't see it being a problem.

Apologies if this is more of a COBOL question, but this is maybe a Fedora-specific problem so I thought it would be best to ask it here. I'm working on a project using GLFW. We've set it up so that the GLFW cmake script is called from our own CMakeLists.txt, so GLFW is being treated as if it's part of our own project. This works fine on the 'ancient' CentOS machines in our school's computer lab, but now I want to work from my laptop, which has had Fedora on it since yesterday. The problem is that when I run cmake, I see this: code:I know there's a GLFW package, but my partner and I agreed to build all libraries for this project from source so that we can keep it consistent across multiple systems. I ran the Intel Graphics Drivers Installer, thinking that maybe this was a problem with the drivers provided by Fedora, but that hasn't solved the problem. Maybe the school's sysadmins used blood magic to make everything work okay on CentOS. tl;dr wtf do i have to do to compile against opengl on fedora edit: Nevermind, it turns out I needed mesa-libGL-devel. And I also needed a whole bunch of libraries but I found them all. Compile -> install library mentioned in error -> repeat. Yaoi Gagarin fucked around with this message at 20:51 on May 16, 2015 |

Is there a "right" way/best practice to get software that's newer than what's in the distribution's repository? For example, if I'm reading this right, the latest stable version of Fedora only has version 2 of Mono, while the upstream is on version 4. I could get version 4 by moving the system to Rawhide, but then I'm on a nightly update schedule and everything on my system is going to be changing all the time and it's just like Arch all over again.  The way I see it, my options are:
I'm leaning towards #3 as the right answer, but there might be something I'm missing, and in any case I'd like a second opinion. #2 would be probably be my fallback, but then I have to get all the dependencies myself and keep track of updates myself. Also, even though I'm using Fedora as an example, I'd still like to know what the best practices are in general. I'm not tied to it, either, so if the solution is actually "use distribution X" I'll gladly switch.

The RAM isn't a problem, I have 16 GB so I can definitely give 8 to the one VM I'll ever run, but I've only got 4c/8t so it would probably be a bad idea to give the vm exclusive use of anything, if that's even possible on windows. Maybe I'll try it again tonight and see what happens.

I liked KDE but it behaves erratically on my work computer (kubuntu 16.04 lts I think). Sometimes pressing alt+f1 to open the applications menu doesn't work and you have to hit it one or two more times. Most recently it's started treating some keyboard inputs as shortcuts, kind of like windows with sticky keys on. It completely refuses to let me type the 's' key, and 'q' causes the activities pane to open up. I don't care too much because I won't be using that computer for much longer but the general jankiness of the experience has kind of soured me on KDE. E: I use fedora with gnome on my Linux VM at home and it's very solid. All I had to do was use gnome tweak tool to change a few things.

'KDE won't let me type the letter S' would be the sort of bug a lot of people would notice, you know. 100% sure, it's the first thing I thought of. Tried the keyboard on Windows and it was fine, tried another keyboard on the KDE machine, same results. Shift+s works though, so you can type lowercase if you caps lock and then shift+s. Absolutely no idea how this even happens. Pretty sure the keys also work fine under tty1, it's just the X/KDE environment that's borked somehow

Absolutely everyone who ever goes within 50 feet of a unix-like machine should learn hjkl, i, escape, :wq, and :q! This is so when said machine invariably gets completely hosed you can still edit config files on it.

Bit of a strange question but, if I built a computer without a GPU what could I do to actually install and configure Linux on it? Obviously once the network is up you can ssh in and do whatever but how do you get it to that point? On an embedded board with no screen I would connect to a serial port to use the shell, can I do something similar on a PC? Context being I want to set up a server at home and it seems silly to spend money on a GPU just to run the installer. I know some motherboards have IPMI that solves this problem completely but I don't know if I'll actually end up getting one of those.

apropos man posted:Last week I bought my first Ryzen rig (well, mobo and CPU). I wanted more cores, as I've recently been getting more interested in running a variety of OSes in ESXi and remotely accessing the desktop. I already have a home-made Linux server which is used for keeping important/personal stuff, which is purely a command line environment. Going to build a combination nas/application server, and also use it for occasional video encoding. It'll run Plex, backup my Windows PC, and maybe host that whole suite of programs for getting stuff off Usenet automatically. And I'm sure over time I will find more uses for it. Running a local dns server and doing the steam caching thing maybe? Basic plan is: - 8 core Ryzen (probably 1700 like you) - some sweet spot of ram capacity vs price, if I can get 64 GB that would be perfect - probably a used SAS HBA of some kind? - a whole lot of hard drives in either zfs or md raid - little nvme boot ssd I haven't decided what distro to use, but it'll probably be either fedora or Debian. I haven't had a Linux computer at home since college so it should be a fun project.

apropos man posted:1700 is such a good price at the moment the only downside I can think of is that the price may slip when Zen2 comes out. You may want to try out Proxmox (https://en.wikipedia.org/wiki/Proxmox_Virtual_Environment). It's based on Debian and is similar to a free version of ESXi. I tried it the other week and, while I find ESXi a bit easer to use, Proxmox has ZFS built into it. There's a decent amount of documentation and forum advice for running it, too. I wish ESXi had native ZFS. What's a good setup for using proxmox as both VM host and NAS? I'm imagining something like: Proxmox has separate datasets for storing media, the Plex metadata/config databases, and my other computers' backups, plus 1+ datasets for random crap I want to store on it Plex + any related programs can run in either a VM of lxc container with the relevant datasets mounted in using bind mounts or something The backup program lives in it's own VM or container Another VM or container has access to the media dataset and the random crap datasets and exposes them to the network over samba I could even combine the Plex and samba VMs/containers and use open media vault or something

The Milkman posted:Docker is a PITA to set up (especially if you're learning as you go) but once it's all working it's much simpler to maintain. FreeNAS plugins work fine but they're often pretty far out of date. Then, things get iffy if you update through other means. You can roll your own jails but you're still at the mercy of the Ports upstream. If you're looking to learn linux some Docker/container knowledge will be far more useful, as neat as jails are. I've looked into docker and ZoL a bit and from what I can tell, you can't use the overlay2 storage driver on top of a zfs dataset, and the zfs storage driver is only supported on Ubuntu. It's probably fine for home use though
