[arch-general] Problem with libimobiledevice, ifuse, and idevices
by Joaquin Villanova 17 May '13

17 May '13

Think something is broken in gvfs-afc, ifuse and friends while working with idevices. Nautilus shows me the devices in the right panel (the favorites one), both documentiation and the device itself and always show this error when trying to mont. <code>Message did not receive a reply (timeout by message bus)</code> I think I've done my homework on bbs, #archlinux and googling, and found the only way peopple resolved this problem was with ppas in *buntus so i want to look deeper... Also i got this from dmesg output when trying to mount manually with ifuse: <code> [ 105.595108] ifuse[500]: segfault at 2dd0 ip 00007ff49b7efc05 sp 00007ff4998e5cd8 error 4 in libimobiledevice.so.4.0.1[7ff49b7e3000+1a000] </code> But the interesting part is that <b> Shotwell can import photos from the device </b>. Surprisingly Rhytmbox cannot play music from it. In an iPad2 ( i'm going to suggest to Apple to change its name to <b> iCrap </b>) neither Shotwell or Rhythmbox can get photos/music from the device. I'm running iOS 6.3 (latest version). Also for more info here is my uname -a, also i think is important to mention that i'm using GNOME (latest version from main repos). <code> Linux arch 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux </code> I'm happy enough because i can retrieve at least the photos from the iPhone, but is annoying that this stopped to work.

[arch-general] about the removal of that systemd symlink...
by David Benfell 17 May '13

17 May '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was alarmed, I think unnecessarily, when I saw the message that a symlink for systemd was removed on an upgrade. As near as I can tell, the boot sequence still relies on init, which links to the right place. Is there a better way to keep track of changes like this so I'm not surprised?

[arch-general] Sound broken, using pulse audio
by Carlos Alegria Galicia 17 May '13

17 May '13

Hi all, After the last kernel upgrade, my sound is not working after weaking up from hibernate. The device "PulseAudio" is shown in alsamixer, PulseAudio is up and running, the channels are shown in pavucontrol and even the level sound bar is showing the audio levels, but there is no sound. Everything works after shutting down - starting up again my system (not even using restart). I am using systemd to hibernate / restart my laptop. Thanks in advance, -- Carlos Alegría Galicia,

[arch-general] Broken sound with Linux 3.9.2 on Acer laptop
by BlissSam 17 May '13

17 May '13

After upgrading to 3.9.2 kernel, the sound did not work. However, the system CAN recognize my sound card, and my sound card appeared in `alsamixer` Downgrading the kernel can solve the problem. Providing more info: Acer Aspire laptop, with Intel i5 CPU, 2nd generation SandyBridge. `uname -a`: > Linux brilliant-laptop 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux `lspci | grep Audio`: > 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) `dmesg`: > Pasted here: http://p.vim-cn.com/cbbcw `cat .pulse/daemon.pa`: > default-sample-rate = 48000 > alternate-sample-rate = 44100 > default-sample-format = float32le `cat /etc/modprobe.d/alsa-base.conf`: > options snd-hda-intel model=acer (This file aims to fix another bug.

[arch-general] 'Check out-of-date packages' tool
by Anatol Pomozov 17 May '13

17 May '13

Hi everyone Per discussion in 'pacman-dev' maillist [1] I implemented a tool that tries to find Arch out-of-date packages. The tool scans PKGBUILD files is /var/abs directory, extracts download url and then tries to probe download urls for the next version. Next versions look like X.Y.Z+1 X.Y+1.0 X+1.0.0 If any of the new versions presents on the download server it reports to user as 'new version available'. Here is the tool sources https://github.com/anatol/pkgoutofdate To make its usage even more pleasant I added it to AUR https://aur.archlinux.org/packages/pkgoutofdate-git/ To use it please install pkgoutofdate-git package: $ yaourt -S pkgoutofdate-git Then update abs database and run tool itself: $ sudo abs && pkgoutofdate That's it. The result looks like ....... closure-linter: new version found - 2.3.8 => 2.3.9 perl-data-dump: new version found - 1.21 => 1.22 wgetpaste: new version found - 2.20 => 2.21 fillets-ng-data: new version found - 1.0.0 => 1.0.1 tablelist: new version found - 5.5 => 5.6 ...... There are some fals positive and negative results though, mostly because download servers return different sort of weird responses. I still work on work-arounds for all these cases. Hope you find this tool useful and it will help to make Arch software even more bleeding edge. [1] https://mailman.archlinux.org/pipermail/pacman-dev/2013-March/thread.html#1…

There seems to have been a problem with pacman update today: :: Starting full system upgrade... resolving dependencies... looking for inter-conflicts... error: failed to prepare transaction (could not satisfy dependencies) :: cyrus-sasl: requires libsasl=2.1.23 :: cyrus-sasl-gssapi: requires libsasl=2.1.23 Yet the current version is the above referred version but libsasl won't update on its own!

[arch-general] gcc: loop do not terminate

I have just been hit by something: lano1106@hpmini ~/dev/gcc-test $ g++ --version g++ (GCC) 4.8.0 20130502 (prerelease) Copyright (C) 2013 Free Software Foundation, Inc.

For example int SATD (int* diff, int use_hadamard) { int k, satd = 0, m[16], dd, d[16]; ... for (dd=d[k=0]; k<16; dd=d[++k]) satd += (dd < 0 ? -dd : dd); accesses d[16] before the loop is exited with the k<16 check. This causes the compiler to optimize away the exit test because the new value of k must be in the range [0, 15] according to ISO C. GCC starting with version 4.8 has a new option -fno-aggressive-loop-optimizations that may help here. If it does, then this is a clear sign that your code is not conforming to ISO C and it is not a GCC bug. I am surprised that I didn't hit the problem before but I am seriously considering using '-fno-aggressive-loop-optimizations' in my own makepkg.conf. I just want to test others feeling on this discovery to see if it wouldn't be a good idea to make the switch standard in Arch... ________________________________ CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.

[arch-general] libvirtd - save shutdown and systemd
by Guus Snijders 14 May '13

14 May '13

Hey all, I'm pretty sure this is a fairly basic question, but i am a bit confused on systemd targets. It has been a while since i converted my systems to systemd and most of it seems to be working ok. Now i am looking for a way to automatically save my VM's to disk in case i forget to shutdown/save one before shutting down the host. After some searching, i stumbled upon this in man systemd-halt.service: " Immediately before executing the actual system halt/poweroff/reboot/kexec systemd-shutdown will run all executables in /usr/lib/systemd/system-shutdown/ and pass one arguments to them: either "halt", "poweroff", "reboot" or "kexec", depending on the chosen action. All executables in this directory are executed in parallel, and execution of the action is not continued before all executables finished. " So at least one way would be place a script that calls "/etc/rc.d/libvirtd-guests stop" (or equivalent, it's not hard to replace) in /etc/systemd/system-shutdown/ . My main question is if this would be a "correct" way or that i could better write some custom unit file to do this? The tricky part is that i am /not/ interested in an automatic resume of previously running guests, only saving them in case i forgot. I'd be very interested in hearing opinions. mvg, Guus

[arch-general] gtkmm and VMware Workstation
by Guillermo Leira 13 May '13

13 May '13

Hello! An advice for VMware Workstation users: upgrading to gtkmm 2.24.3-1 on x86_64 makes VMware Workstation 8.0.6 crash on start or after a few seconds. I don't know about other versions. It happens with kernel 3.8.11 and 3.9.2. Downgrading to gtkmm 2.24.2-2 solves it (after an hour of trial and error). I'll create a bug report tomorrow. Too late for me now. Best Regards, Guillermo Leira

[arch-general] Linux 3.9.2-1-ARCH cures blank screen
by Whiskers 13 May '13

13 May '13

The blank screen I first reported in January with Linux-3.7.3-1-i686 seems to have been cured by the latest update to Linux-3.9.2-1-i686 (and/or other updates that have happened at the same time). (Using the nouveau graphics driver). But the desktop and mouse settings in XFCe4 aren't all working. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~
