Sounds really nice. I've never heard about the kernel and software you mention, and after reading about them it sounds really interesting. Do you have any reference (website/blog/wiki/whatever) with these optimizations, apart from the Arch Wiki?

The TTY running X is busy running the xinit/xsession process, until you kill that process you shouldn't be able to get the command line prompt to run another program. The only way to overcome this shortcoming would be to run xinit in the background, which I wouldn't reccomend. Regards John

[arch-general] libusbx
by Fons Adriaensen 10 Jun '12

10 Jun '12

Regarding the libusb / libusbx replacement, the following may be of interest to authors using it: I have one app using libusb, after the upgrade it consistently segfaulted on calling libusb_exit(0). The '0' argument in this call and some others means my code was using the 'default context'. Using an explicit context solved the problem. So either the the 'default context' isn't supported anymore (no mention of that in the docs), or there's some bug related to it in libusbx. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

[arch-general] [linux-lts] unable to auto mount some usb device
by GSC 10 Jun '12

10 Jun '12

After recent update of linux-lts to 3.0.33, it fails to auto mount my android device as usb storage(moto atrix2). My other usb devices are auto mounted successfully, just this one fail to auto mount every time. It can be manually mount successfully. And I tried linux kernel(3.3.8), auto mounted successfully. Only in current linux-lts the device fail to automatically mount every time. Any one experiencing the same? Which log should I analyse to solve it?

[arch-general] iPhone not -completely- detected (ifuse doesn't work)
by Sergi Pons Freixes 10 Jun '12

10 Jun '12

Hi All, After following the wiki ( https://wiki.archlinux.org/index.php/Iphone ) and looking for similar problems on the forum ( https://bbs.archlinux.org/viewtopic.php?id=133822 ), I still can not get my iPhone to be detected by ifuse, in order to be able to sync music. The iPhone has iOS 5.1.1 and is not jailbroken. The system has installed: linux-lqx 3.4.2-1 ifuse 1.1.2-1 libimobiledevice-git 20120610-1 usbmuxd-git 20120610-1 libplist 1.8-2 I boot up the system (fuse module is loaded at startup), unlock the iPhone, and connect it to the system. I got: usb 2-2: new high-speed USB device number 3 using ehci_hcd ehci_hcd 0000:00:1d.7: dma_pool_free ehci_qh, f2d1e060/fffff060 (bad dma) usb 2-2: New USB device found, idVendor=05ac, idProduct=1297 usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-2: Product: iPhone usb 2-2: Manufacturer: Apple Inc. But when running ifuse command to mount it: No device found, is it connected? If it is make sure that your user has permissions to access the raw usb device. If you're still having issues try unplugging the device and reconnecting it. On the other hand, Shotwell is able to see it, and import pictures. In case it's relevant, I'm using Gnome with gvfs-fuse-daemon. Any clue about what could be failing (apart form me :P)? Regards, Sergi

[arch-general] Location of sample websites
by Jayesh Badwaik 10 Jun '12

10 Jun '12

Hi, I am using wordpress and I found that the sample wordpress site is installed in the /srv/http location. I find it convenient that all such sample/getting started things should be actually installed someplace like /usr/share/wordpress/ and then anyone who wants to use the site can copy paste the files to wherever he wants and then use them accordingly. Is there any reason for the current behaviour? Am I missing some aspect? Thanks for your reply in advance. -- Cheers and Regards Jayesh Badwaik stop html mail | always bottom-post www.asciiribbon.org | www.netmeister.org/news/learn2quote.html
