[arch-general] Solution for issues with "green" HDDs when gvfs is installed
by Ralf Mardorf 22 Aug '13

22 Aug '13

Hi :) to help those who have "green" HDDs that can't keep asleep when gvfs is installed, I replaced the dummy package for gvfs I had installed by the real gvfs package and try to solve this issue by another method. There absolutely in no need to install gvfs on my machine, but since there's a "green" EU Regulation, soon or later more people will experience that their "green" drives will spin down and up again and again. The assumption is that it's udisks that wakes up sleeping drives, for gvfs seemingly configurable by /usr/share/gvfs/remote-volume-monitors/. This assumption might be wrong. $ systemctl status udisks udisks.service - UDisks Loaded: loaded (/usr/lib/systemd/system/udisks.service; disabled) Active: inactive (dead) $ cat /usr/share/gvfs/remote-volume-monitors/udisks2.monitor [RemoteVolumeMonitor] Name=GProxyVolumeMonitorUDisks2 DBusName=org.gtk.Private.UDisks2VolumeMonitor IsNative=true NativePriority=4 What are "IsNative" and "NativePriority" for? I still search myself, but any hints are welcome, to disable _what ever_ wakes up such "green" drives. Without gvfs those drives keep asleep. Regards, Ralf

[arch-general] Intel SNA artifacts in Firefox
by Paul Gideon Dann 22 Aug '13

22 Aug '13

Since the xf86-video-intel update that enabled SNA by default, I've noticed that some areas of some web pages (mostly flat backgrounds) in Firefox suffer from heavy graphical corruption, as if those areas are being used as rendering buffers elsewhere: bits of web pages from other tabs, etc... It goes away when I scroll the page. It happens regularly, every couple of minutes or more. This is on a Dell Latitude E5520 (Sandybridge i5) with KDE. I'm wondering if anyone else is seeing this?

[arch-general] Pip2 commands throw error
by Squall Lionheart 21 Aug '13

21 Aug '13

Hello, Since upgrading to version 1.4.1 in July of python2-pip, I have been receiving this Exception on the commands I execute. Received an update to version 1.4.1-1 today and the error persists. This is a desktop machine and I get the same error on a server running Parabola. I tried a manual install of pip-1.4.1 and distribute on Slackware and everything runs as it should. Have not tried the manual install on Arch yet since I would prefer to use the packaged versions.

[arch-general] Does leading slash matter in install scriptlets?
by lolilolicon 21 Aug '13

21 Aug '13

Many install scriptlets include the leading slash in file paths, e.g. post_install() { update-desktop-database -q gtk-update-icon-cache -q -t -f /usr/share/icons/hicolor } while some strip the leading slash, post_install() { update-desktop-database -q gtk-update-icon-cache -q -t -f usr/share/icons/hicolor } Would this make a difference with `pacman -S --root <path> <pkg>`? If not, is there any case in which it would make a difference?

[arch-general] Systemd inside LXC: user sessions are not automatically removed on logout
by Leonid Isaev 20 Aug '13

20 Aug '13

Hi, I have been experimenting with archlinux guests inside LXC containers, and noticed that when a user logs out, systemd-logind won't remove the session. This is reproducible on all (archlinux x86_64) host-guest, testing-stable combinations. Here is an example (fserv1 is a container hostname). The only way to login is through ssh (sshd.service is enabled and running inside the container). fserv1-~ >>> loginctl list-sessions SESSION UID USER SEAT 5 0 root 16 2001 fserv1user 18 2001 fserv1user 19 2001 fserv1user 34 2001 fserv1user fserv1-~ >>> w 16:28:27 up 22:08, 1 user, load average: 0.00, 0.01, 0.05 USER TTY LOGIN@ IDLE JCPU PCPU WHAT fserv1us pts/0 16:06 3.00s 0.11s 0.00s w fserv1-~ >>> id uid=2001(fserv1user) gid=100(users) groups=100(users),190(systemd-journal) fserv1-~ >>> loginctl list-users UID USER 0 root 2001 fserv1user 2 users listed. fserv1-~ >>> ps -u root -U root | grep -i sh 18 ? 00:00:00 sshd 1506 ? 00:00:00 sshd As root: [root@fserv1 ~]# loginctl session-status 16 16 - fserv1user (2001) Since: Mon 2013-08-19 03:59:13 UTC; 12h ago Leader: 748 Remote: hermes.skynet Service: sshd; type tty; class user State: closing CGroup: systemd:/system/lxc_fserv1.service/user/2001.user/16.session [root@fserv1 ~]# loginctl session-status 5 5 - root (0) Since: Sun 2013-08-18 19:48:16 UTC; 20h ago Leader: 141 Remote: hermes.skynet Service: sshd; type tty; class user State: closing CGroup: systemd:/system/lxc_fserv1.service/user/0.user/5.session [root@fserv1 ~]# loginctl kill-session 16 Failed to issue method call: No such process [root@fserv1 ~]# loginctl kill-session 5 Failed to issue method call: No such process However, sshd works correctly, e.g. Aug 18 19:48:16 fserv1 sshd[141]: Accepted password for root from 10.0.0.154 port 39596 ssh2 Aug 18 19:48:16 fserv1 sshd[141]: pam_unix(sshd:session): session opened for user root by (uid=0) Aug 18 19:48:16 fserv1 systemd-logind[22]: New session 5 of user root.

There are no errors/warnings reported by journalctl. The only systemd units masked inside the guests are: systemd-udevd-control.socket, systemd-udevd-kernel.socket, systemd-udevd.service, and proc-sys-fs-binfmt_misc.automount. Is this my mistake somewhere or a systemd issue? Thanks, Leonid. -- Leonid Isaev GnuPG key: 0x164B5A6D Fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D

[arch-general] no mp4 playback with VLC
by Nelson Marambio 19 Aug '13

19 Aug '13

Hi, folks, I downloaded a video file from YouTube which makes my players hang. VLC neither plays audio or video but just remains as if no file was in the playlist (in fact it is). When I start vlc (vlc -v) from console and try to play that video file vlc writes to the console mp4 stream warning: unknown box type tft (incompletely loaded) When I feed Google with this message I receive just similar results ('tft' seems to be individual to my problem) but not a solution. ****************** When I try to play the file with GNOME Mplayer it works but without the sound. I already checked in the preferences that I don't use the internal volume control of Mplayer. Does anyone have a hint for me ? I am unsure if a codec is missing because VLC would tell me that ?!? As Mplayer can decode the images I think the file is not corrupted. But what about the sound ? ******************** The video file is located here: http://www.youtube.com/watch?v=30ifeJZSQ64 (480p, file size is approx. 415 MByte) I downloaded it with this Firefox extension: http://www.downloadhelper.net/ output vlc: http://pastebin.com/mhYDeGK4 output GNOME Mplayer: http://pastebin.com/yp6U6w9d Thanks in advance, Nelson.

[arch-general] Question about repository updates and atomicity
by Johannes Ernst 19 Aug '13

19 Aug '13

I'm trying to understand what may and may not go wrong between package uploads to a repository, repository synchronization via rsync (which seems to be the preferred method for mirrors to get their stuff) and downloads via pacman. Assume a developer uploads a new version of two packages to a repository. My understanding is that uploads delete the older version of the uploaded package currently in the repository. (unlike other package management systems e.g. debian's where multiple versions of the same package can reside in the same repository). An hour later, a mirror repository starts rsycing. While the rsync is ongoing, a user uses pacman to download both packages from the mirror. Question: what mechanisms exists, if any, to avoid that the user gets the old version of package A and the new version of package B? (assume the rsync is still ongoing while the download occurs) It seems the "safe" way of doing the rsync would be to take down the mirror during the critical section (when all old versions are removed and the new ones put there instead), and restart it afterwards? Or is there something somewhere that I'm not seeing? The debian guys probably keep the old version(s) around for exactly that reason... Any insight very much appreciated ... Cheers, Johannes.

Hi :) when I try to build current linux-rt I get "No space left on device", resp. df shows "tmpfs 100% /tmp". What can I do? Add "tmpfs /tmp tmpfs nodev,nosuid,size=3G 0 0" to /etc/fstab?

[arch-general] LightDM hangs when checking the password
by Ralf Mardorf 17 Aug '13

17 Aug '13

Hi :) I wonder if it's an issue with linux-rt 3.10.6-rt3 or randomly something else went wrong. Perhaps caused by 3.10.6-rt3 or not, but a security process or similar seems to be locked on my machine. After installing and booting into the 3.10.6-rt3 an update hanged when checking the keyring. I had to remove /var/lib/pacman/db.lck and could update using 3.10.6-2-ARCH, but when I now try to start a session for 3.10.6-rt3, LightDM hangs when checking the password, I only was able to start one session for this kernel. After downgrading to 3.8.13-rt14-1-rt there isn't this issue anymore and even with 3.10.6-rt3 there were no issues when I want to log in booted in kernel 3.10.6-2-ARCH. In don't know what to check. What log searching for what information. At the moment I simply use 3.8.13-rt14-1-rt. Regards, Ralf
