[arch-general] usb webcam no audio
by Matthew Monaco 22 Jul '11

22 Jul '11

I haven't been able to get audio on my webcam for a while. My initial guess is that it has to do with all of the udev changes. I'm using gnome w/ pulseaudio. The audio properties show the device on the input tab, but it doesn't detect any activity. everything.log: Jul 21 23:54:08 newguy kernel: [11606.472285] usb 4-5: new high speed USB device number 2 using ehci_hcd Jul 21 23:54:09 newguy mtp-probe: checking bus 4, device 2: "/sys/devices/pci0000:00/0000:00:13.2/usb4/4-5" Jul 21 23:54:09 newguy mtp-probe: bus: 4, device: 2 was not an MTP device Jul 21 23:54:09 newguy kernel: [11607.089065] Linux media interface: v0.10 Jul 21 23:54:09 newguy kernel: [11607.121723] Linux video capture interface: v2.00 Jul 21 23:54:09 newguy kernel: [11607.129054] uvcvideo: Found UVC 1.00 device Hercules Dualpix Exchange (06f8:3005) Jul 21 23:54:09 newguy kernel: [11607.134791] input: Hercules Dualpix Exchange as /devices/pci0000:00/0000:00:13.2/usb4/4-5/4-5:1.0/input/input6 Jul 21 23:54:09 newguy kernel: [11607.134938] usbcore: registered new interface driver uvcvideo Jul 21 23:54:09 newguy kernel: [11607.134943] USB Video Class driver (v1.0.0) Jul 21 23:54:09 newguy kernel: [11607.197743] 2:3:1: cannot get freq at ep 0x84 Jul 21 23:54:09 newguy kernel: [11607.198679] usbcore: registered new interface driver snd-usb-audio Jul 21 23:54:09 newguy kernel: [11607.251849] 2:3:1: cannot get freq at ep 0x84 Jul 21 23:54:09 newguy kernel: [11607.276979] 2:3:1: cannot get freq at ep 0x84 Jul 22 03:54:09 newguy rtkit-daemon[1012]: Recovering from system lockup, not allowing further RT threads.

[arch-general] Moving qgis from [community] into the AUR.
by Thomas Dziedzic 22 Jul '11

22 Jul '11

QWT was bumped to 6.0 and qgis is currently incompatible with the new version. In order to update qwt, we will have to drop qgis into the aur. I have looked into patching qgis to be compatible with qwt 6. I managed to get an initial patch accepted, but there is a lot more work to be done, on code that I'm unfamiliar with. upstream bug report: http://hub.qgis.org/issues/3562 -Thomas Dziedzic

[arch-general] makepkg and its dependencies, how to create a good build chroot?
by Magnus Therning 21 Jul '11

21 Jul '11

For a while now I've been using some scripts to handle the details for creating build chroots, updating them, and triggering builds in them. It's all part of my work with building Haskell packages for Arch. To create a chroot I used this line: mkarchroot -f -C ${pacman_conf} \ -M /usr/share/devtools/makepkg-${arch}.conf ${CHROOT_ROOTDIR} \ util-linux-ng pacman sudo wget file grep base-devel ghc Well, that is, I used that line up until yesterday, and it worked fine until then. Yesterday I ran into the problem that the command `find`, which is used by `makepkg`, was missing in the chroot. A little while later I found the same to be true for `gzip`. So, I added `findutils` and `gzip` to the list of packages to be installed. Now, `makepkg` comes in the `pacman` package, and it doesn't have any dependencies on either of these packages, not even an optional dependency. This leaves me with three questions: 1. Why does `pacman` (the package) not depend on `findutils` and `gzip`, when `makepkg` clearly needs both those packages to function properly? 2. Are there any other packages I ought to install in a build chroot besides those I've listed above? 3. Dependencies of packages change over time, so is there a shortcut to making sure I always create a good build chroot (a group maybe)? /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus I invented the term Object-Oriented, and I can tell you I did not have C++ in mind. -- Alan Kay

[arch-general] Panic - no sound devices after upgrade
by Fons Adriaensen 21 Jul '11

21 Jul '11

After a routine upgrade it seems I don't have any sound devices any more. More in detail: * The driver for my card (RME HDSP MADI, snd_hdpsm) is loaded. * aplay -L tells me there is only the 'null' device. * (re)starting /etc/rc.d/alsa doesn't change things. * There is *no* /dev/pcm at all. * /sys/class/sound only has a link to a timer device. * No traces in dmesg or /var/log/messages of anything going wrong. I suspect udev fails to do the right things. * /etc/udev/rules.d is empty * /etc/udev/udev.conf contains only the line udev_log="err" This is a professional studio and I'm expecting clients tomorrow at 09:00. Any ideas ? TIA, -- FA

[arch-general] Not a good time for ProAudio work? WAS: Panic - no sound devices after upgrade
by Bernardo Barros 20 Jul '11

20 Jul '11

All those issues regarding sound cards and lv2 plug-ins right now. This all mean it will take time until Ardour3 (stable) come out and udev fixes and updates? I tried to figure out the differences between my fedora and arch boxes, I cound not find an easy explanation why the firewire soundcard works on fedora and not on arch. I tried different kernels (including lts), udevs and everything I could think of, including editing the rules.d folder. Or we can try some kind of concentrated effort to find and fix those problems (specially sound card problems) until they hit more users? Sorry, maybe that's just a couple of us, one or two people. I don't really know how many.

[arch-general] X cursor problem on new install
by D. R. Evans 20 Jul '11

20 Jul '11

I just installed arch for the first time (trying it out since I am unhappy with the state of Kubuntu). I have, I think, followed the installation instructions carefully. Everything seemed OK until I tried to run X. The cursor is offset from where it should be. If I move the mouse to the right, the cursor stops about 2/3 of the way across the screen and won't go any farther. If I move the mouse to the left, the cursor disappears off the left hand side of the screen and reappears on the right hand side. It stops moving to the left a short distance from the right border on the screen. The display of windows on the screen looks fine; it's just the cursor that seems to be wrong. 1. I have tried two mice; both behave the same way. 2. I used wgetpaste as instructed at wiki.archlinux.org/index.php/Beginners'_Guide#Graphical_User_Interface: ~/.xinitrc does not exist /etc/X11/xorg.conf does not exist /var/log/Xorg.0.log is at paste.pocoo.org/show/428974 /var/log/Xorg.0.log.old is at paste.pocoo.org/show/428976 Obviously, I need to get this resolved before proceeding any further with installing a desktop environment.

[arch-general] testing splitted LibreOffice 3.4.2rc1
by Andreas Radke 20 Jul '11

20 Jul '11

It's done. LibreOffice has been split into libreoffice-common and application packages -writer,base,calc,... For better look'n feel you should also install libreoffice-gnome for use in any gtk desktop and libreoffice-kde4 if you want. The en-US language is no more included in the -common pkg. So everyone will have to install at least one language pack,e.g. libreoffice-en-US. I hope I've covered the deps all well. Please test fresh installations and also upgrading from last 3.4.1 release. The new 3.4.2rc1 should be already safe for daily usage. Recommended way for new installations should be to either install libreoffice-common the should ask for a langpack or directly install the langpack of your choice that will pull in the -common pkg. Then you install the application packages you want. It's also possible to install the "libreoffice" group package. If you upgrade you should get libreoffice-common installed showing the needed infos. So get it from the testing repo and report bugs. -Andy

[arch-general] virtualbox additions package naming
by Ionut Biru 19 Jul '11

19 Jul '11

I've been criticized a lot because I choose poorly the name for guest additions. Right now the packages are like this: virtualbox-addtitions - contains the iso with guest additions for linux/windows/etc and is installed on host virtualbox-guest-additions - contains guest additions only for an arch linux system as guest. virtualbo-guest-modules - modules only for an arch linux system as guest. Now that virtualbox 4.1 is released I need help choosing this names. -- Ionuț
