kde-3.4.0 media ioslave problem [solved]

hothead · Last edited by hothead on Tue Mar 22, 2005 7:09 pm; edited 1 time in total

You need to install pmount in order to get the media:/ ioslave to work properly
an ebuild is available at https://bugs.gentoo.org/show_bug.cgi?id=69575

When trying to access a unmounted cd/dvd via the media ioslave
"I get a popup message "The process for the media protocol died unexpectedly."
Anyway the media seemed to get mounted. When I access the media for a second time after closing the popup message and the stalled mount window the contend of the media content is shown as expected. When I mount the device before accessing it there is no error message.

Does somebody has the same problem or better a solution?

Regards

I have the same problem and also noticed that Video-DVDs are always shown as mounted (even when they're not). Choosing "open in new window" mounts them with the same pop-up error message. Hope that gets fixed in 3.4.1

I've got the same problem with the thing dying. Annoying.

is there already a bug on bugs.kde.org? if not, considder creating one... (after checking this problem also exists on eg a kubuntu livecd)

Well, i found a way to fix it. Reading a few posts on kde-bugs it seems that kded requires a binary called pmount. I couldn't find it in portage, so i got it from here. It needs sysfsutils to compile.
Don't know if it's a good solution, but at least it makes the media ioslave work without those errors. My Video-DVDs are still shown as mounted.
@hothead: I didn't use the split builds. I used the "DO_NOT_COMPILE" option on some packages, but not on kdebase, which seems to be the only relevant package to this issue.

I already commited a bug to the kde bugtracker as well as to the gentoo bugtracker
http://bugs.kde.org/show_bug.cgi?id=102086

Maybe you want also take a look at a interesting howto I found at the gentoo wiki.
http://wiki.kde.org/tiki-index.php?page=DBUS

At the momement I try out this article and pmount.

I emerge pmount, but it did nothing to help the problem.
So i read the manual. Ran a test mount with the command.. Then it worked next time..
But do i have to run it each time i boot? how does it work to fix that bug?

Eject command for kde ioslaves still won't work tho =/.
Works fine in console, but nothing happens for the rclick one.

hi,
I have the following problem. I can't see devices in media:/
although if I plug in a (eg) usb stick it shows up in media:/ and on the desktop... so it seems like hal/dbus is working just fine. Is there something I should do with fstab maybe?

thanx for any help

hothead · Posted: Wed Mar 23, 2005 1:16 am Post subject:

Are you sure dbus and hald are running?
ps -A | grep dbu
ps -A | grep hald

a fstab edited by fsab-sync should look like that

kmare · Posted: Wed Mar 23, 2005 2:11 am Post subject:

yes... dbus and hal are running... also the /etc/fstab is edited by fstab-sync... it's just that media:/ doesn't want to show anything. Only devices that I plug after the system is booted... no partition or dvdrom devices...

thanx though

PS: I have hal and dbus to boot at the "default" runlevel. Should I put them at the "boot" maybe?

EDIT: there's no "managed" in fstab... I think that there should be a managed entry for each device handled by fstab-sync, right?

hothead · Posted: Wed Mar 23, 2005 1:12 pm Post subject:

the case is that fstab-sync should do that for you.
Do you use udev? hald needs an udev enabled system.

yes... udev is installed and running...and I also disabled devfs... I really don't know what else to do... I read a lot about the subject and everything seems to be running as it should but I don't get my media:/

btw: when I had devfs enabled together with udev the devices were there, but I was getting some strange kernel messages. Reading someone's post the solution was to disable devfs, as I did...

anyway thank you for helping...

Got everything to work with default settings, all i had to do is add messagebus and haldaemon to my user's groups.

The only thing not working for me is the eject command. It unmounts the cdrom but never eject it and then I have to switch to a console to 'eject /dev/hdwhatever'. Will we be able in the near future to simply push the eject button on the drive to get the disc back with the dbus-hal-media-slave scheme?

I have installed pmount-0.7.1 alongside hal and dbus and it seems to work well. It produces an icon in konqueror "media:/" when you plug in USB storage or load an optical disk. By setting KDE background to display all devices except hard drives, both mounted and unmounted, everything is smooth. I particularly like that I get an unmounted icon when inserting a device, which I can then mount, unmount as required which disappears when I eject/remove the device.

In my opinion, pmount is *not* needed. I can view both mounted/unmounted cdroms, dvds and usbsticks through my media:/ protocol and on the desktop. And I can eject/umount/safely remove the hardware in any order I feel like also. And I do not have pmount installed on my system. My hotplugging is now working better than it ever has on any system Ive tried. You need the following packages: hal, udev and dbus. You should *not* use ivman together with KDE. Search the forums for an answer to why not.

Also, the following USE-flags are needed: USE="hal udev usb -devfsd" You might also throw in the following USE-flags, since they will provide alot of fun later on: USE="zeroconf kdeenablefinal" You will need to use KDE3.4 and recompile parts of KDE after adding hal and udev to your USE-flags, possibly kdelibs and kdebase.

Edit: You will also have to create a /media directory on the root filesystem. Your /etc/fstab should be automatically updated when plugging in the appropriate hardware, so it is no need to add an entry for removable medias (like cdroms, floppies, usbsticks etc) in /etc/fstab.

Maybe a bit off topic, but I have a question about ivman and pmount:

If I want to automount my USB harddisk or memorystick without KDE and without using a kind of fstab-sync (no window manager used, booted in the shell),
is that possible with HAL / udev / pmount and ivman?
Or does ivman always use fstab-sync?
