[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.

[arch-general] Strange file in home directory
by Sławek Kapłoński 17 Sep '16

Hello, I found recently strange (for me) file in my home directory. Name of this file is "on": [13:45:14] slawek@dell:~$ file on on: GNU dbm 1.x or ndbm database, little endian, 64-bit I think that it is created by Mutt because when I removed it and started Mutt then it was created again. Do You know what is this file for, what creates it (is it really Mutt) and maybe how can I disable creation of this file? -- Best regards / Pozdrawiam Sławek Kapłoński slawek(a)kaplonski.pl

[arch-general] GNU Privacy Assistant window sizing problem?
by Francis Gerund 17 Sep '16

17 Sep '16

Hello. Running Arch x86-64, Gnome 3, Linux 4.7.4-1-ARCH #1 SMP PREEMPT Thu Sep 15 15:24:29 CEST 2016 x86_64 GNU/Linux. Screeen is 15" 1366 x 768, 60 Hz. In GNU Privacy Assistant, when I open the "backend preferences" window, it opens with the "basic" options selected, correctly sized. But when I then select either the "advanced" or "options", the window expands well below the lower screen edge. Some of the options are then hidden, and I can not seem to find a way to resize the "backend preferences" window. Since the bottom row of buttons is completely hidden, I can not even change the setting that are visible, except the "basic" options. I have searched the forum, wiki, and online, without success. Has anyone else seen this problem, and if so, found a solution?

[arch-general] Not being able to upgrade system because of catalyst-hook
by Foxtrot Mike 14 Sep '16

14 Sep '16

Hi all, For almost a month, I have been unable to upgrade my system (# sudo pacman -Su), apparently because catalyst-hook won't work with Linux 4.7. I thought that in a few weeks atmost, catalyst-hook would be 'upgraded' to support Linux 4.7, but still no luck. I am a beginner, so may be I am missing something. I couldn't find any such info on archWiki. Here's how I have been upgrading my system for the last year: ===================================================================== ===================================================================== >sudo pacman -Syy [sudo] password for foxtrot: :: Synchronizing package databases... xorg117 25.0 KiB 60.3K/s 00:00 [##############################################################] 100 catalyst 12.3 KiB 616K/s 00:00 [##############################################################] 100 core 119.4 KiB 64.3K/s 00:02 [##############################################################] 100 extra 1760.5 KiB 70.5K/s 00:25 [##############################################################] 100 community 3.6 MiB 116K/s 00:32 [##############################################################] 100 multilib 172.6 KiB 119K/s 00:01 [##############################################################] 100 >sudo pacman -Su :: Starting full system upgrade... :: Replace libdbus with core/dbus?

Any help would be appreciated! Regards, Fulcrum

[arch-general] Arch svntogit/package.git what is Diffstat bargraph displaying? Lines?
by David C. Rankin 12 Sep '16

12 Sep '16

All, After updates, I was investigating the removal of Arch-specific FT2_SUBPIXEL_HINTING from freetype2 (enabling infinality patch) and I was looking at the changes on the svntogit/package.git page, e.g. https://git.archlinux.org/svntogit/packages.git/diff/?h=packages/freetype2&… At the top of the page there is a Diffstat graph showing a horizontal bar graph of red/green bars on the right side of the graph, e.g. Diffstat -rw-r--r-- trunk/0001-Enable-table- validation-modules.patch 18 ====== -rw-r--r-- trunk/0002-Enable-subpixel- rendering.patch 10 ==== -rw-r--r-- trunk/0003-Enable-infinality- subpixel-hinting.patch 27 ========= -rw-r--r-- trunk/0003-Make-subpixel-hinting- mode-configurable.patch 88 ===========.. -rw-r--r-- trunk/0004-Keep-default-interpreter- version-as-35.patch 29 ==========... -rw-r--r-- trunk/PKGBUILD 36 ==========... -rw-r--r-- trunk/freetype2.install 15 ===== -rw-r--r-- trunk/freetype2.sh 12 ==== ^ ^ | | +---------------+ this information What is 'this information' on the graph showing? Lines added/deleted? Votes for change? -- David C. Rankin, J.D.,P.E.
