Mate desktop, login produces up to ten caja instances
by Fred Smith 10 Aug '13

10 Aug '13

On F19 with Mate desktop, sometimes after login 8 or 9 or even 10 copies of Caja (Mate File Manger) are started up. Most of the time not, but perhaps once every day or two this will happen. the rest of the time it's completely normal. I found these /var/log/messages entries at around the right time, but I'm not certain whether they are from login or the boot a small bit earlier: Jul 19 19:23:56 aspirebox dbus-daemon[556]: dbus[556]: [system] Rejected send me ssage, 2 matched rules; type="method_call", sender=":1.52" (uid=1000 pid=1410 co mm="caja -n ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.12" (uid=0 pid=638 comm="/us r/sbin/console-kit-daemon --no-daemon ") Jul 19 19:23:56 aspirebox dbus[556]: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.52" (uid=1000 pid=1410 comm="caja -n ") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.12" (uid=0 pid=638 comm="/usr/sbin/console-kit-daemon --no-daemon ") Anybody got any clues? thanks!

SELinux error on every policy package update
by Suvayu Ali 07 Aug '13

07 Aug '13

Hi, I have been having this weird problem; everytime I there is a selinux-policy update, I get the following error: libsepol.print_missing_requirements: hotplug's global requirements were not met: bool init_systemd (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed! FWIW, this machine was updated from F17 to F19 with yum. I tried searching for the error above, but could not make sense of what I found. Any ideas? -- Suvayu Open source is the future.

Re: The state of blu-ray burning in linux is terrible
by Thomas Schmitt 06 Aug '13

06 Aug '13

Hi, sorry for breaking the thread. I was not subscribed up to now and did not yet find an archive that exposes message ids. -------------------------------------------------------------- It is not that bad with Blu-ray. At least with the backends. (I am the developer of libburn and use BD-R and BD-RE media daily.) But wodim (or "cdrecord") out of cdrkit should really be used only for CD. The slowliness of BD media comes from their Defect Management which checkreads the written blocks while they are still present in the drive's buffer. In case of poor read quality the blocks get written again or redirected to the Spare Area where the data get stored in replacement blocks. This checkreading reduces write speed to at most half of the nominal speed of drive and BD medium. BD-R do Defect Management by default if they are formatted. BD-RE can only be used formatted and do Defect Management by default. -------------------------------------------------------------- Original cdrecord out of cdrtools was already discussed in the this thread. To my knowledge it is fast with BD-R, because it does not format them. It is not fast with BD-RE, because it uses SCSI command WRITE(10) which does not allow to override the slow Defect Management. -------------------------------------------------------------- growisofs out of dvd+rw-tools has a little bug with BD-R. https://bugzilla.redhat.com/show_bug.cgi?id=858029 https://bugzilla.redhat.com/show_bug.cgi?id=868527 It is supposed to be fixed in dvd+rw-tools-7.1-13.fc19 The tiny patch is shown in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=713016 Workaround is to explicitely format the BD-R before use by dvd+rw-format /dev/sr0 or to use option -use-the-force-luke=spare:none when giving an unformatted BD-R to growisofs. growisofs formats BD-R by default and then uses slow Defect Management. This can be prevented by option -use-the-force-luke=spare:none growisofs has no means to prevent Defect Management on BD-RE media. -------------------------------------------------------------- My own programs, libburn based cdrskin and xorriso, do not format BD-R by default. So they are as fast as with cdrecord. Other than with cdrecord it is possible to format BD-R on request cdrskin -v dev=/dev/sr0 blank=format_if_needed xorriso -outdev /dev/sr0 -format as_needed which makes them capable of slow Defect Management. Other than growisofs and cdrecord, cdrskin and xorriso offer the opportunity to disable Defect Management on formatted BD-R and on BD-RE cdrskin stream_recording=on ...cdrecord-like-burn-options... xorriso -stream_recording on ...xorriso-burn-commands... This is especially helpful with 2x BD-RE, which elsewise need an awfully long time to write their capacity of 22.5 GiB. Have a nice day :) Thomas

Do I need avahi?
by Timothy Murphy 05 Aug '13

05 Aug '13

I recently noticed that I have been getting warnings avahi-daemon[5884]: dbus-protocol.c: Too many objects for client ':1.15', client request failed. on my server. I must admit I didn't know I was running avahi on the server. I looked at a couple of avahi howtos, and it seemed that for almost any usage other packages are required, in particular nss-mdns . If this is in fact required by avahi, it seems surprising that it is not automatically installed at the same time. (None of the examples of avahi usage actually worked on my system.) But my real query is whether avahi (or zeroconf) could actually offer me anything useful. I'm running dhcpd on the server, and I'm not looking for information about printers or other users on my home network. Also, is there any way of discovering who "client 1.15" is? And is anything likely to go wrong if I simply "service avahi-daemon stop"? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 School of Mathematics, Trinity College, Dublin 2, Ireland

Gnome classic working in F19?
by "Paul-Erik Törrönen" 05 Aug '13

05 Aug '13

Just want to check first if I am the only one having this problem with an upgraded F19 setup. Some background: Upgraded the system from F18 (and previously from 17-16-15) with fedup --network. Before the upgrade I was running Gnome fine in the classical style (dropdown app menu, no hotspots, workspace grid on lower bar etc.). After the upgrade logged on with Gnome Classic selected -> worked fairly ok, I have a grey top and bottom bar. Logged out and in again in order to get some additional settings (the workspace for both dual displays). After the login (making sure that I still have the Gnome classic selected) the top and bottom bars are not the same. Specifically the bottom bar (where the running apps should be displayed as well as the workspace app) is missing altogether and the top bar is now the new Gnome-styled, ie. has the hotspot and no app-menu at all. This is reproducable, if I log out from this state, select the normal gnome session, then I (again) get the same new Gnome desktop as described above, and after an additional logout + login with the Gnome Classic selected, then I end back in the actual classic for that particular session. So it seems that the mode selection is not really working, and neither is the selection remembered correctly. Does this sound familiar to anyone?

Disable built-in WiFi card so that USB WiFi device gets used.
by Rolf Turner 03 Aug '13

03 Aug '13

I have a Toshiba Satellite L850 Laptop for which the WiFi card appears to be incompatible with any drivers available for Linux. To try to get around this problem I recently purchased a USB WiFi device: An ASUS USB-N110. They (ASUS) provide drivers which one must install. After a great deal of travail and fumbling around (the instructions were both unclear --- apparently written by someone for whom English was at best a *third* language --- and slightly misleading) I managed to get the device *partially* working. The device appears to work immediately after boot-up but if I close the lid of my laptop, (which causes it to go into hibernation (???) mode) or if I log out and log back in, the WiFi connection gets lost. When I try to restore the connection it seems to keep trying to use the WiFi card that is built into the laptop rather than the USB WiFi device. (And the built-in device doesn't work; as I said, its drivers are incompatible with Linux OSes. Which is why I bought the USN-N10 in the first place.) The only way to get the laptop to make use of the USB WiFi device seems to be to shut down and restart. This is unsatisfactory. Is there any way to "disable" the (non-functional) built-in WiFi card so that the laptop will *not* try to use it but will rather go straight to the (functional) USB device? I Googled around a bit and found some instructions for disabling the built-in WiFi card under Ubuntu, but these instruction did not (as far as I could tell) mesh with the Fedora system that I am running. Can anyone tell me how to do what I want under Fedora? If you reply, ***PLEASE*** be as clear and explicit as you possibly can. I am not terribly swift with OS matters. I know and understand ***some*** things, but there are huge lacunae in my knowledge. I am running Fedora 17; output of "uname -a" is: > Linux localhost.localdomain 3.3.4-5.fc17.x86_64 #1 SMP Mon May 7 > 17:29:34 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Thanks for any help that anyone can give me. cheers, Rolf Turner

Works great for me. From the doc referenced above. *Note:*Users of Fedora/Mandriva might want to install the*dkms*package (not available on openSUSE) to ensure that the VirtualBox host kernel modules (/vboxdrv/,/vboxnetflt/and/vboxnetadp/) are properly updated if the linux kernel version changes during the next kernel update.

How to create launchers on panel in Gnome 3 Classic Mode?
by Eric Smith 01 Aug '13

01 Aug '13

Is there some way to create launchers on the Gnome 3 Classic Mode panel, as was easily done in Gnome 2? I'm trying really hard to like Gnome 3 Classic Mode, but having a very difficult time of it, because it seems to only provide a superficial resemblance to the Gnome 2 desktop, without actually providing comparable functionality.

Hello, I'm using Linux 3.10.x kernel and I have AMD proprietary graphics driver running akmod. The 3.9.9 kernel series was working fine until the latest update came. Now I can't log in using the new kernel, tthe screen goes black and it logs itself out. I can't even log back in. The older kernel is working flawlessly though. Any solution?

Backup settings
by Martin S 01 Aug '13

01 Aug '13

There apprently is a backup service in Fedora, which can automatically copy files to various "cloud-services" or other places. What is needed to be able to add /var/log/yum.log to the files that are backed up. The file is greyed out, and I can't select it. How do I solve this or should I go for some other tool for this?
