jako root: gpasswd -a jmeno_uzivatele cdrw cdrom video. Kdyžtak ty kategorie za sebou, nevím.

[swigrid]

nepomohlo tu je moj postup:

swigrid ~ # gpasswd -a swigrid cdrw cdrom video
Adding user swigrid to group cdrw
swigrid ~ # exit
logout
swigrid@swigrid ~ $ mplayer dvd://

cat /etc/fstab; id swigrid
Co používáš za mounter ? :)

[swigrid]

nechapem otazku ako mounter? v linuxe nie vsetky udalosti su mi este jasne :) normalne mount /mnt/dvd alebo mount /dev/cdrom0 /mnt/dvd. alebo nie to si myslel? :).

ked som dal
swigrid ~ # cat /etc/fstab; id swigrid
tak mi vypisalo toto:

# /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/ fstab,v 1.14 2003/10/13 20:03:38 azarah Exp $

# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.

# < fs > < mountpoint > < type > < opts > < dump/pass >

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

# Adding the following line to /etc/fstab should take care of this:

Ok

/dev/cdroms/cdrom0 /mnt/dvd iso9660 noauto,ro 0 0
 /dev/cdroms/cdrom1 /mnt/cdrw iso9660 noauto,ro 0 0

změň na

/dev/cdroms/cdrom0 /mnt/dvd iso9660 users,noauto,ro 0 0
 /dev/cdroms/cdrom1 /mnt/cdrw iso9660 users,noauto,ro 0 0

Pak

/etc/init.d/ivman restart

a snad to půjde.. když ne, ta řekni, co ti vypíše emerge -pv ivman dbus

[swigrid]

swigrid ~ # /etc/init.d/ivman restart
-su: /etc/init.d/ivman: No such file or directory
swigrid ~ # emerge -pv ivman

These are the packages that I would merge, in order:

no ale tu uz teraz vidim problem, prvy subor co treba nainstalovat, ten doxygen. som dnes rano roby celkovy uprade systemu a na tom to zastalo. a este som neskumal ze co to, ale toto je kratky vypis hlasky (dufam ze je tam nieco co ti bude davat zmysel)

Huh, tak to jsem mimo. Můžeš zkusit restartovat počítač, aby se 100% projevily ty změny v /etc/fstab. Doufám, že mě za tuhle radu nebude nikdo kamenovat... no a když to nepůjde, tak ti musí poradit někdo jiný, sorry, taky začínám

[swigrid]

ten restart pomohol na prejavene zmeny mplayer dvd:// funguje uz aj v normalnom uzivatelskom rezime. a ten dalsi problem hmm to skusim niekde inde. dakujem :)

[David Watzke]

Není zač, já jsem rád, že jsem pomohl

[swigrid]

a v tom logu sandbox sa nachadza toto:

open_wr: /usr/lib/graphviz/config
open_wr: /usr/lib/graphviz/config
open_wr: /usr/lib/graphviz/config
open_wr: /usr/lib/graphviz/config
open_wr: /usr/lib/graphviz/config

a opakuje sa tato hlaska v logu asi aj 50x mozno aj viac

Tady vidíš, že se tam ty nový skupiny nevyskytují. Změna skupin se projeví až po novým přihlášení uživatele ;)
