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

[QUOTE=kaukassus;45192140]To those using btrfs, I have a small question. I am thinking about going Archlinux on my Laptop and I am wondering. How stable is btrfs on Kernel 3.14/3.15? Also, is it worth it using it over ext4? I have never used btrfs outside of a VM.[/QUOTE] I've been using it for almost a year now, it's pretty stable. There's not much of a difference if you don't use its features, but I really like its realtime-compression support. However you have to defragment it sometimes, and disable CoW for journalctl. Otherwise journalctl gets incredibly slow for somereason.

[QUOTE=supervoltage;45193157]Someone really needs to explain to me some general advantages and disadvantages of the various file systems, I never really understood what makes a filesystem better than the other. I am blindly sticking with ext4 because it [I]seems[/I] to work fine, but I'd like to know if there's anything better and for what it's better.[/QUOTE] I'd say you start out by reading up on the different file systems on Wikipedia. That's a somewhat good introduction to what they can do, and how they work. When in doubt, just follow links for a few days and keep reading until you feel you know the basics of it. Some filesystems, like ZFS and Btrfs, are a bit different and might be a good idea to try out in virtual machines.

Even my phone runs btrfs and I've had no issues. [editline]24th June 2014[/editline] It's a Jolla, in case anyone was wondering. Has other problems, though. Such as constant rebooting for no apparent reason, on some days.

They're both copy-on-write filesystems (two files are mostly the same, just write down changes separately), and they both have cool functionality like snapshots, fault-tolerance, on-the-fly transparent compression (ZFS with a ton of RAM + compression is pretty fucking magical when it comes to sequential reads because of compression) etc. The main thing for the standard consumer is that ZFS was made by Oracle (aka Hitler), is trademarked by Oracle (aka Hitler), and has a shit license, so it can never be included in the Linux kernel, which is why only BSDtards care about it, whilst crying "muh features" and "muh enterprise solution". On the other hand, btrfs is built directly into the kernel, and you don't need to fuck around with kernel modules etc. to use it. I use btrfs on my laptop. I like it.

I'm thinking about reformating my Laptop and go with arch, because Windows is just vomiting all over itself right now. While I'm at it, i'm gonna go with a LUKS+BTRFS (no LVM) setup.I already did some small-scale testing of the Environment I want, and it looks promising. This is gonna be interesting. The main problem right now would be the nvidia optimus stuff, but I think I'm just gonna go full nvidia because I charge it everywhere.

Featurewise ZFS is way ahead of btrfs (which is still in experimental phase for some reason although it seems to be pretty stable for the most part), being a 128bit FS as opposed to Btrfs 64bit FS, it also supports a wide variety of features that have been planned but not yet implemented in Btrfs (last time I checked btrfs hadn't properly implemented their send/receive functions, are they working now?). On the other hand, Btrfs supports converting from ext3/4 filesystems to Btrfs, so you can "upgrade" to that kind of system. Exactly how it works I haven't checked right now, but it is indeed a very useful feature. Especially for enterprises and such. I'm guessing you should be able to do this with multiple disks and add them all to a single pool? But I don't know. ZFS doesn't support converting to ZFS, you'll need to specify the partition as being a Solaris partition, then add the ZFS pool to it, and in many cases this works best if you just add entire disks seeing as ZFS appearantly doesn't like resizing the Solaris partitions. Although moving them should work fine.

Hello Archlinux, it's been a while since you've been on my main Rig.

Actually wanted to record something on my laptop for once, used slop, ffmpeg and the bash as provided here, but got instantly this error. Seems to be a problem within slop. Doing slop -b=3 gives me this. [code]diwako@diwakotop ~/slop/slop $ ./sloop.bash record test.webm X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 33 (X_GrabKey) Serial number of failed request: 25 Current serial number in output stream: 25 [/code]

It failed to gain access. Failed request was for X_GrabKey, so it couldn't intercept keyboard input, I assume. Try sudo?

Same result.

Compile the kernel whilst performing a handstand and singing "The Free Software Song". I honestly have no idea, that's an X11 error, and madness lies at the end of that path.

Run slop with --nokeyboard

I kind of wish [url=http://www.gobolinux.org/] this[/url] had more packages/'recipes' available. It's a really nice idea, but...Bah.

[QUOTE=FlamingSpaz;45203289]Run slop with --nokeyboard[/QUOTE] It worked, thank you.

No matter what I did I could not get it to grab the keyboard with 100% reliability. So I added a --nokeyboard option that disables the keyboard canceling feature, I really should look into how SFML grabs keyboard input and copy it. [editline]asf[/editline] Oh I made slop if this post is confusing at all.

I miss Linux. I wanna go back to it. But even the proprietary nvidia drivers perform like ass on my laptop. :saddowns:

any of you guys know of any cool themes for KDE? I've been meaning to get into KDE since I love how it feels, but something puts me off which I'm not sure what is. I think it's how it looks, or it could be how the desktop/settings are arranged, not entirely sure

almost lost complete mouse use today. i was trying to get my magic mouse to connect via bluetooth. I went to system settings then mouse settings and ticked the "Enable Touchpad" off. Thank god tab works so well.

[QUOTE=lavacano;45205799]What card?[/QUOTE] Quadro FX 570M... It's basically a GDDR3 8600M GT.

is it worth trying linux if my wifi card isnt supported by linux apparently ill have to do a long fix just to get it to work on any distro

Which wifi card? I bet you anything it'll work fine on Arch (As long as it's not one of those godawful usb wifi adapters )

its a god awful usb wifi adapter netgear wna3100

It'd probably be easier and more efficient to get an actual wifi adapter or just plug in with an ethernet cord.

yea, it would be that isnt an option for me though, atm until i can get a proper connection, is linux worth dabbling in?

[QUOTE=Wingz;45216854]yea, it would be that isnt an option for me though, atm until i can get a proper connection, is linux worth dabbling in?[/QUOTE] That depends on what you intend on doing. Most people would probably prefer to be connected to the internet, so if that's not a thing you can do you might want to skip this round. However, if you're willing to get it fixed (and there is a fix?), then I'd say just go for it. It's a great system to operate and work in, and the ease of use of many Linux distributions is quite remarkable. And I'm not gonna lie. Using the terminal is fun as hell.

so i've been flipping a bitch because i couldn't get grub to use graphical mode at all for the past few weeks turns out i haven't been building it with sdl/truetype support

Rebooted my laptop/server and ethernet didn't come back up =( I feel like my old, overheating HP is begging me to let it die.
