General Linux Chat and Small Questions v. I broke my Arch Install - Hardware & Software

btrfs has TRIM support enabled by default, for SSDs. ext4 you need to edit your fstab, or enable fstrim.service [editline]10th December 2014[/editline] Some big name distros will likely do this for you if you use their automated installers

So I'm trying like fuck to set up a mail server on my VPS. It seems to work, but only if I log in via SSH and use shit like mutt or sendmail to send and receive. On my desktop machine I have a Claws Mail account set up and (seemingly) working, but If I attempt to use it to send email to, say, my gmail account, it breaks. Only on my desktop though, if I log in as mentioned before, on the VPS, then it works. However, I cannot pull in sent items or inbox items from the VPS to my local machine either, so I have no fucking idea. It uses IMAP only and SMTP, and is a mix of postfix and dovecot. Halp? [editline]12th December 2014[/editline] Oh, it's worth mentioning that the VPS runs Ubuntu 14.04, and the postfix setup is mostly just default, and same goes for the dovecot. Mostly.

I remember having to go into my domain provider account to set up a couple of records back when I had a Linode hooked into a co.cc domain, did you do that?

any idea what to do if linux doesn't accept keyboard input from a new keyboard? usually that stuff works out of the box for me, but with this new one it doesn't. it's a Corsair K95 RGB. the backlight comes on, but it won't accept input at all. [editline]13th December 2014[/editline] forgot to mention, running Arch

I can also send from gmail to my VPS email account, and read the emails on the VPS, but nothing gets to my local machine. Seems to me that it could be a problem with my local setup, but I am pretty sure it isnt Claws Mail fucking up, yet I have never actually set something like this up before. Im gonna head to bed now, but I will test it with Mutt on my local machine as well, just to make sure it isnt a local issue. To expand, when sending to my gmail account from Claws Mail (that is, setting the rcpt to: [email]name@gmail.com[/email]) I get a "relay denied" error. However, doing the same when SSHd into my VPS, it works fine.

Post your configs then?

[QUOTE=mastersrp;46700767]Seems that it is not supported in the kernel yet. [url]https://github.com/ccMSC/ckb[/url] [/QUOTE] this made it work, thanks!

[url=http://i.imgur.com/mjOlfbC.gif]Rejoice![/url] OverlayFS finally made it into the kernel! I'm probably never going to use it myself, but it's nice to finally see it included.

I currently use this UnionFS mount command: [code]mount -t unionfs -o nodev,dirs=/dev/shm/.portage_rw=rw:/usr/portage=ro unionfs /usr/portage[/code] Does OverlayFS support this or am I going to have to modify my init script? [editline]14th December 2014[/editline] the UnionFS FUSE module hangs if I do that, so I have to compile it into the kernel with the patch

[QUOTE=mastersrp;46717099]Why not just use OverlayFS and ditch UnionFS?[/QUOTE] Because I don't know if it will work in OverlayFS as is. (I also don't know the pros and cons besides OverlayFS being officially part of the kernel now) The specific issue is using /usr/portage as both a read-only directory and the mount point. In the UnionFS FUSE module it hangs (probably some infinite loop nonsense) but in compiled-in UnionFS it works perfectly. If I can just switch out "unionfs" for "overlayfs" and have it work perfectly, I'll gladly switch next kernel update. But if I have to move the read only directory somewhere else, it would be less work to just keep running the patch command for unionfs until I finally get off my lazy ass and start moving shit around.

What's special about both those file systems?

awesome, will migrate next time i do kernel updates

Installing Fedora Server 21 on an old laptop of mine right now. I like the Anaconda installer, it's improved since I last ran into it. This looks so simple, a Windows admin could do this.

Anaconda is nice, but the way it has you manually partition drives is kinda clunky [editline]18th December 2014[/editline] At least it was in Fedora 20 [editline]18th December 2014[/editline] Their website is a lot more professional looking now

Made the switch for good. There's no need for me to be on windows anymore.

[QUOTE=josm;46757323]Made the switch for good. There's no need for me to be on windows anymore.[/QUOTE] Stronger than me, I still dual boot for games..

[QUOTE=Naelstrom;46758235]Stronger than me, I still dual boot for games..[/QUOTE] I used to play a lot of games that required windows to play, but nowadays I only play LoL and GW2 and both of those can be made to work on Linux. So, really, I should have done this a long time ago.

I want someone to globally throw /dev/random in the garbage, rename urandom to random, and shut up everyone that comments on it, without understanding how secure random numbers work. Fucking Reddit commenters.

My laptop's on Mint 17.1 full time now. I don't know what wizardry they've done lately but with Steam, Firefox, and the full Cinnamon DE running it's only taking up 700mb of RAM. That's like, Windows XP level of efficiency, goddamn. [editline]20th December 2014[/editline] I'm used to Steam using up 700MB by itself :v:

Well, if i'm using wolfram alpha right that's about 19 4KUHD/12-bit framebuffers or 2 hours of 48KHz/16 bit uncompressed audio. That's a lot of memory for a desktop environment and two browsers, unless you have lots of tabs.

Even when I used to use Arch and nothing but Openbox and Tint2 Steam by itself would easily take up 500mb of memory or so, and Firefox with a handful of tabs (Reddit, FP, arch wiki) taking up another 500mb :v:

When I hit enter I instantly get "Did not receive a response from the server". I tried the fix suggested [URL="https://wiki.archlinux.org/index.php/League_of_Legends#Troubleshooting"]here[/URL], but it didn't do anything for me.

so I switched from xfce to unity and still have the xubunutu splash on boot and still have xfce's login screen. How can I get change those?

[QUOTE=XxThreedogxX;46764536]so I switched from xfce to unity and still have the xubunutu splash on boot and still have xfce's login screen. How can I get change those?[/QUOTE] I believe Xubuntu uses LightDM as its display manager, so you should be able to change the login screen through that. the splash though, no idea what xubuntu uses to display its splash screen [editline]21st December 2014[/editline] [url]https://wiki.ubuntu.com/LightDM[/url]

Doesen't Xubuntu use plymouth for the splash screen?

[QUOTE=Lyokanthrope;46762058][/QUOTE] I believe xorg uses like 100 MB by itself, and steam uses loads of memory because it's a weird mix between a package manager and a browser, not to mention it can and probably uses its own version of some libraries because of incompatibility or whatever. firefox is just firefox being firefox. I can boot 9front/plan9 and get a gui with just 16MB, i wish more drivers were ported to it since it was released as GPLv2 some time ago, it has the potential to be so much better than linux. Unrelated: i've seen wine mentioned in this thread some times but not gallium-nine, anyone here knows that it exists?, it gives a performance boost and sometimes even works better than the default D3D -> OGL thing wine uses by default.

doesn't gallium nine only work with the open source drivers though?
