Slackware :: Disabling KDE Dolphin Preview And Kio_thumbnail
Oct 3, 2010
Hi everybody! I am completely stumped with KDE's Dolphin's preview policy. It started with me realizing that when as much as I mouse over an encrypted file (say, an ODS file created and encrypted with OpenOffice), KDE pops up a password prompt. The culprit identifies itself as kio_thumbnail. This is a feature so apparently useless, I would like to disable it no matter what. I know a work-around: hiding the Information panel seems to work. But I like the information panel. On top of that, the same kio_thumbnail does on occasion decide that my computer is underutilized (it feels like it happens during the idle times). It allocates my entire RAM, all 4 GiB of it, and does something fancy. It doesn't crash, however, and goes away a few minutes after I poke the computer.
I don't want a daemonized thumbnailer, is there a way to disable kio_thumbnail or make it be quiet and do nothing? I tried fooling around with Dolphin. I went into Settings / Configure Dolphin... and
1. Disabled all services,
2. Unchecked everything in General / Previews.
I did the same to Konqueror.
As far as I can tell, this had no effect whatsoever. Dolphin still previews all the files it previewed before, and still tries to preview encrypted files when Information panel is open. I am running unmodified Dolphin 1.4 on KDE 4.4.3, the same ones that came with Slackware 13.1 x64.

I cannot use preview function in Dolphin to preview JPG files that the size is bigger than 3MB. It is no problem when the photos' size are smaller than 3MB. Do any one got the same problem?

Dolphin crashes when previewing PNG files - with other image files (PS, PDF, JPG, DVI) when you roll the mouse over the file you get a preview pic in the top right corner - when I roll it over a PNG file, it halts for a second then crashes.

Since I upgraded to 11.3 I don't see that the View > Preview mode is broken. Image icons are created, but they all look like the icons in the picture below. When I move the zoom slider the largest sized icons come out fine. Anyone an idea how to solve this problem? Is there any repository that I can use to get more recent versions that should have fixed these bugs? I just noticed that PNG images come out right, so it could be something related to JPG files.

After I manually installed multimedia codecs, like w32codecall, I got Linux to play movies and I also got thumbnail previews of them in Dolphin. However, I noticed that recently Dolphin doesn't display my thumbnails anymore. I don't quite recall whether the any video player could use my installed codecs, at least xine works. The only thing that could have caused that is actually the automatic system updates I received. I still have my multimedia codecs installed, but Dolphin doesn't show the movie previews anymore.

How this can be done? I already have the necessary codecs installed and have kde 4.2.

How can I disable the folder preview which occur when the mouse stay to a folder icon on the desktop (I use "Folder view" on the desktop) ?
Similarly, is it possible to disable the popup displaying comment and help when the mouse stay over a icon shortcut to an application ? If yes, how and where ?

I am using Slackware64 13.37 and every once and awhile I will get a notification that the kernel is disabling IRQ #16. When this happens it feels like I lose 3D acceleration. KDE becomes very sluggish and lags like crazy. Even when I type into text boxes they lag. The only way to fix it temporarily is to reboot, but then it will happen again in a few days.
My lspci output:

I've been ignoring this problem for about a week but its getting on my last nerve. Dolphin keeps freezing for about 20 seconds when ever I try to move or open files sometimes, It will just sit there and then once it returns it will very quickly execute my command. It seems im not the only one having this issue [url]
I still can't seem to find a fix. I'm running the most recent current BTW

I am running 64-bit current. I have not identified which update started the Dolphin crashes, but it recently has been happening very often, usually within a few seconds of starting it, but not always.
Googling suggested that it might be a dbus issue, so I rolled my own package using dbus-1.4.0 and the slackbuild from the 64 bit current source.
Dolphin has been rock solid since. I noticed that there was an 'allow root globally' patch which I commented out. I am guessing that this may affect applications that I have not used yet or the issue has been fixed in version 1.4.
I have not seen any evidence that other current users have had this problem, but maybe Robby would consider an upgrade?

I have been using KDE4 for some time now as a test and have noticed what at first seems to be a major omission. There is no way to run dolphin or konqueror as root. Old style KDE3 in SLackware 12 had the "root konqueror" option, (or whatever it was named in the KDE menus), but KDE4 doesn't have this. I tried adding a new menu itme in KDE4 to run dolphin as root but it had odd errors about "could not start process" and "could not to talk to klauncher" - it would not display any files from my directory. Konqueror had similar odd problems - something about klauncher and Dbus server. This is a pain as there are sometimes files I wish to move/delete which I need to be root to do and it would be nice to have a gui to do this.
Anyone got any quick ways (from KDE) of achieving this or setting up a KDE menu item to run a file manager (dolphin/konqueror) as root ? I don't always want to have to run "su -c mc" in a terminal to do admin stuff in the filesystem and I don't want to run KDE as root.

My slackware 13.37 64 with 4 gig ram , has a strange thing in dolphin. My machine runs very well with kDE4.6.1 from alien and no other problems. When I copy files to a folder it does not show , I have to close dolphin and reopen to see those files. If I click on a compressed file and select extract folder here it does the same.

I have set System Settings --> Advanced --> Removable Devices to 'Enable automatic mounting of removable media' --> 'Mount all removable media at login' and 'Automatically mount all removable media when attached'.
But, the SlackDVD does not appear in ls /media until after I double-click the 'SlackDVD' in Dolphin.

I have some problems accessing NTFS USB devices from Dolphin. If I mount by hand the device, mount -t ntfs-3g /dev/sdc1 /media/disk I can access to the disk from Dolphin. mount command reports: /dev/sdc1 on /media/disk type fuseblk (rw,allow_other,blksize=512)When the same disk is mounted through Dolphin (by clickin on the disk icon), I cannot see any content. mount command reports: /dev/sdc1 on /media/FLS-U2-300 type fuseblk suid,nodev,allow_other,blksize=512,default_permissions)root@obelix:~# As you can see, mount command reports different configurations. I suspect the extra parameters used by Dolphine causing problems but I don't know how to configure KDE to change the mount options. This problem is new to Slackware 13.1. My previous 13.0 configuration had not that problem

Is there any Slackware-current or Slackware64-current users in the LQ Slackware forum experiencing lags or slowdown on Dolphin file manager on KDE 4.5.1? I experienced this first on KDE 4.5.0, after the current update KDE to 4.5.1 I still have this problem.
Hovering mouse on a file can take a while, opening a text file with kwrite took several seconds and dolphin window will appear blank (like hang). Sometimes Dolphin crashed when opening file, changing directory or hovering mouse on a file.
Quick googling points to this discussion at http://dot.kde.org/2010/08/31/kde-releases-451 which suggest a bug in libdbus.

I've just did a fresh Slackware 13.1 install on a 32-bit box for friends of mine. It's an older machine with an AMD Athlon XP 2500. Generally everything works just fine, with one exception, however.Connecting a LUKS encrypted USB harddisk is notified by KDE. Clicking on the device icon in Dolphin opens the dialog asking for the LUKS passphrase. No error message appears, but the file system is not opened and mounted, anyway.However, before another attempt I have to "remove" the device in Dolphin.Output of dmesg:
Code:
# Nov 25 23:58:24 mycomputer kernel: device-mapper: ioctl: unable to remove open device temporary-cryptsetup-3023

Is there anyway to right click on a file in the Dolphin window and select mail to: then kmail should open and the file gets mailed accordingly.
Or some way to implement this?

Dolphin will only open Samba shares if I open them by typing in smb://SERVER-IP. It also does not show up in the Network section of Explorer under Windows 7. How do I fix this? The only Samba share icon that shows up in Dolphin under Network --> Samba Shares is Workgroup. If I click it it changes smb://workgroup, but then it does nothing and shows no files. Here is my Samba server's smb.conf file.
Code:
[global]
workgroup = WORKGROUP

I inserted a disc and tried to access it through Dolphin. It shows up in the directory explorer thing as a disc and with the disc name, but it has a little / thing in the bottom corner of the icon, and when I try to access it, it gives me this long error on the bottom of the file area (can't remember what all it said, something about 'harvey' and being unable to find the directory in /etc/fstab). The same thing happened with an external drive, which seemed to work fine before but now has the same problem.

I downloaded Slackware64-current to give it a try on my laptop and all went well as usual. However when trying to connect to another computer from Dolphin via sftp I was informed that sftp is an 'invalid protocol'. I can use ftp, though. Same thing happens with Konqueror. Using Konsole I can successfully start sftp, although that is not exactly what I want or need. For me, this is really a major problem as my office computer can only be accessed at home via secure shell. I need to be able to upload/download files and folders from there and from other machines. I wasn't really aware of how heavily I depend on this until now. Has anyone else run into this problem? If so, is there a fix or a workaround?

Kernel 2.6.21.5, slackware 12.0
When you do 'man bash', you'll see some words are highlighted. I'll say that the video card has used high intesity in these instances. How do I disable this video card capability? Can this only be done by recompiling the kernel? Of course, I am talking about the text consoles, i.e., the video card in text mode.

I just set up my firewall, and now I can't see any Samba workgroups. It says it can't find any workgroups on my local network, and it may be caused by a firewall. It is a firewall issue because if I disable my firewall, I can see the workgroup. What do I need to open on my firewall to see the workgroup? I am using Slackware64 13.37.
Here is how I set up my firewall.
Code:
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -s 127.0.0.0/8 -d 127.0.0.0/8 -i lo -j ACCEPT
iptables -A INPUT -p icmp -j ACCEPT
I got the commands from here url.

You may know that there was a security release for Adobe Flash Plugin for Linux x86 but not for x86_64. There has been a development:
See : http://labs.adobe.com/downloads/flashplayer10.html
It works fine here. I have a Multilib Slack 13.1 stable.
