Except you could just happen to have it backwards. The few non-sse2 32 bit cpus that run arch could be served their own specialised distribution, while a majority benefits from saving said few cpu cycles. cheers! mar77i

[arch-general] arch-audit: pkg-audit-like tool for Arch Linux
by Andrea Scarpino 24 Sep '16

24 Sep '16

Hi everybody, I'm happy to announce my tiny project named arch-audit[1]. It parses the CVE wiki page[2] and reports which packages on your system are affected by a vulnerability and if a fixed version for that package is already available. Something like pkg-audit on FreeBSD, but not so powerful (yet!!!). I just made it and released, so it's more than alpha and your feedbacks are needed! I hope you find it useful.

[arch-general] What happened to the Beginner's Guide?
by David C. Rankin 23 Sep '16

23 Sep '16

Archdevs, I went to review the Beginner's Guide and it was no longer listed on the main page. I then specifically searched for it, found it in the topics, and then was redirected to the bare-bones "Install" page. What happened to the Beginner's Guide? -- David C. Rankin, J.D.,P.E.

[arch-general] Error when starting Opera
by Francis Gerund 22 Sep '16

22 Sep '16

Hi. Just installed Opera 40.0.2308.54-1. Upon starting Opera, a dialog box pops up saying: --------------------------------------------------------------- "Enter password to unlock you login keyring The password you use to log in to your computer no longer matches that of your login keyring." Password: < password input field >" ----------------------------------------------------------------------------- After about 5 seconds, a grey window pops up, saying: ----------------------------------------------------------------------------- "“Loading... - Opera” is not responding. You may choose to wait a short while for it to continue or force the application to quit entirely." ... followed by two buttons, "Force quit" and "Wait". Clicking "Force quit" exits Opera; clicking "Wait" simply makes the window go away, with Opera started as expected. --------------------------------------------------------------------------------------------------------------------------- Putting in my user password results in the message "The unlock password was incorrrect." If I click cancel, whether or not I enter a password, either way, Opera starts up, with no other (apparent) problem. Changing the user password, and even changing it back, does noting to change the login error message. I did a lengthy configuration of Opera, then re-started it. Same error. I re-installed Opera using pacman -Rsn. Same error. I cound not find any reference to this error in the forums, or any bug report. (Not saying it might not exist, it just did not see it.) This error does not occur for any other application program, including those that require entering a password for elevated privileges, to start. Any ideas?

[arch-general] i3wm (randomly?) freezes; SIGCONT seems to fix it
by Bennett Piater 19 Sep '16

19 Sep '16

Hi all, I've had a very elusive and frustrating problem this week and don't know where to look anymore. Maybe one of you has an idea? :) Since 2016-09-04, i3wm freezes every once and a while; often after waking the screen (even if it wasn't locked), a few times also directly or a few minutes after logging in. I have not yet found a conclusive pattern. The freeze is complete; no reaction to mouse or keyboard activity, not even in the debug logs. However, I can interact with the focused window just fine (I obviously cannot change focus). i3 also doesn't react to IPC calls (tried with i3-msg). Up to now, I had sent SIGTERM to important programs that had been running and KILLed i3 (it doesn't react to SIGTERM, either). Today, in my frustration, I tried sending SIGCONT instead. To my surprise, i3 immediately sprung back to life. What I do not understand is that i3 hasn't been updated in a while, let alone since Sunday. FWIW, I am running the fork i3-gaps instead of i3, but that is very close to upstream and has been stable forever. I posted /var/log/pacman.log from the day when it started on my server [0]. Does anyone have any clue what could be causing this? Thanks, Bennett [0]: https://vps1.piater.name/commie/#dvm1K6lg -- GPG fingerprint: 871F 1047 7DB3 DDED 5FC4 47B2 26C7 E577 EF96 7808

[arch-general] .xsession-errors - can't startx with that file
by Dutch Ingraham 18 Sep '16

18 Sep '16

Hello all: TL;DR: One Arch installation will allow redirecting startx's stderr to a file, one won't. What is the difference between systems? I am having an issue with logging xsession errors. Specifically, if I create an .xsession-errors file in /home/user, then startx with <<startx 2> /home/user/.xsession-errors>>, startx will write to the file, but otherwise error-out and not actually start X. The error, in its entirety, is: "X.Org X Server 1.18.4 Release Date: 2016-07-19 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.5.4-1-ARCH x86_64 Current Operating System: Linux archlinux 4.7.4-1-ARCH #1 SMP PREEMPT Thu Sep 15 15:24:29 CEST 2016 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=763598c6-08b4-44d9-9b21-d4dbd558b107 rw Build Date: 19 July 2016 05:54:24PM Current version of pixman: 0.34.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version.

Closing log file. xinit: giving up xinit: unable to connect to X server: Connection refused xinit: server error" For the correctness of the specific incantation <<startx 2> /home/user/.xsession-errors>>, see these [1][2] threads. In addition, that command works on any number of other distros (Fedora, Gentoo, etc., and even OpenBSD). But here is the real kicker - I have another computer with a very similar Arch installation, i.e., x86_64, fully up-to-date, "full" KDE and other window managers installed, using identical (actually copied from machine-to-machine) .xinitrc files. The above error only happens on one machine, and happens regardless of whether I am trying to start Plasma or just DWM, Awesome, i3, or whatever. Searching for that specific error does return a few hits [3][4], but none of those issues/remedies are similar to mine. Any ideas on how I can determine the differences between the two Arch installations that are causing only one to error-out when redirecting stderr to a file?

Checking https://en.wikipedia.org/wiki/Streaming_SIMD_Extensions and its links suggest AVX was the point where the paths became the same again. AVX was designed in 2008 , but first procesoors that supported it were launched in 2011 . My 2009 AMD opteron 2378 "Barcelona" processor advertises SSE, SSE2, 3DNow & 3DNowExt . I couldn't find specifics about 3DNowExt , but chances are big that software compiled with SSE3 , SSSE3 or SSE4 will crash on pre-2011 AMD processors. LW

[arch-general] pkgstats api
by Chris Stryczynski 18 Sep '16

18 Sep '16

Apologies I sent this through yesterday but without any subject so not sure if it gets picked up. I was wondering if there is an API / JSON endpoint for pkgstats? Saves me having to scrape the page! I'm interested to build a packages / aur frontend.
