[opensuse-factory] permissions for sound, dvd, etc
I would like to change the default permissions for the sound devices and the removable media. Right now (10.2 Alpha 3) the first user wins, meaning whoever logs on first gets the exclusive rights on the devices. Not very user friendly, except when you're the first one. So I tried changing the rules for udev as laid out in /etc/udev/rules.d, but to no avail. I managed to change the group for the devices, but not the permissions (from 0600 to 0666 or at least 0644). I then learned about resmgr and went and changed the file /etc/resmgr.conf.d/99-desktop.conf and added some rules for sound and cdrom devices. Still no success. The next stop was in/etc/PolicyKit/privilege.d. There is a bunch of files which allegedly take care of permissions for all kinds of devices. I changed the file hal-storage-removable-mount-privilege, but that did not have any effect on the permissions for my dvd drive or the usb stick. Before I finally mess up the hal configuration (I already checked: it's in /usr/share/hal and /etc/hal) I was wondering if anyone knows where I actually have to tweak my system to let the other users hear sound and mount dvd's (or at least play a video dvd with kaffeine & friends). I figured it's got to be somewhere between udev, hal, resmgr and PolicyKit. Perhaps with pam also involved? Or is there another mechanism I didn't even think of (yet)? -- confused Andreas --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

I have similar problems, and as user I can't mount any removable device (CD, DVD, pendrive, etc. In /media I found the file .hal-mtab-lock, and the content of mtab is: /dev/sda2 / reiserfs rw,acl,user_xattr 0 0 proc /proc proc rw 0 0 sysfs /sys sysfs rw 0 0 debugfs /sys/kernel/debug debugfs rw 0 0 udev /dev tmpfs rw 0 0 devpts /dev/pts devpts rw,mode=0620,gid=5 0 0 /dev/sda4 /home reiserfs rw,acl,user_xattr 0 0 /dev/sda3 /windows/C vfat rw,noexec,nosuid,nodev,gid=100,umask=0002 0 0 automount(pid2991) /misc autofs rw,fd=4,pgrp=2991,minproto=2,maxproto=4 0 0 automount(pid2993) /net autofs rw,fd=4,pgrp=2993,minproto=2,maxproto=4 0 0 When I insert a Cd appear the popup window in kde asking what to do, and I press ok, appear other window empty and a label "Permiso denegado". Only can mount as root in Konsole, with the command: mount /dev/hda /media The other problem is with digikam, when it try to connect to the cam, it closes.

Remove it and try again. It might be leftover of some crash. -- Regards, Rajko. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

That's not the case. All users logged in via console or xdm have access to sound devices thanks to resmgr (provided that the kernel supports ACLs on /dev). Mounting of removeable media is likely broken due to PolicyKit not beeing properly integrated yet, that's a problem unrelated to device permissions. cu Ludwig -- (o_ Ludwig Nussel //\ SUSE LINUX Products GmbH, Development V_/_ http://www.suse.de/ --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Ludwig, without tweaking anything, right after a "vanilla" installation, the devices /dev/dsp and everything in /dev/snd has the permissions 0600 for the first user who logs in. subsequently logged in users do *not* have any sound. Actually, a KDE session for such users starts with an error Message from arts about the default device being busy. Xine-ui or any other player with direct access to e.g. alsa also sheds an error message about the sound device. After manually changing the file permissions in /dev sound works for the other users too, as expected. If this is not the default behaviour (as I thought), should I file a bug report? -- Gruß Andreas --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Check if they have ACLs. (+ in ls -l output). Alpha3 is known to have bugs here, so you can open a bugreport.
