View Full Version : [SOLVED] Dolphin lags hard on launch & navigation - F15 KDE

So, Dolphin has been lagging on my system for a while now.

When I launch Dolphin it takes a good 30 seconds to be open. Then while navigating it is very laggy and not responsive at all.

Is there a log file somewhere I can look at to see what might be causing this lag?

Krusader on the other hand opens very quickly and there is no lag in the navigation of files and folders.

I prefer to use Dolphin for normal everyday tasks and Krusader for more complex operations. It would be nice if Dolphin was responsive again.

Thanks,
PEZ

install kde 4.7 repo (http://repos.fedorapeople.org/repos/rdieter/kde47/fedora-kde47.repo) then update. 4.7 fixes lots of issues.

I have F15 KDE running on quite a few machines, and I don't see a lag unless I look at a folder that has a very large amount of files/apps/sub-folders. An example would be /usr/bin/. When you open Dolphin it starts normally in your /home folder, so, check and see if you have a inordinate amount of files in /home, check the hidden files also. See if the hidden file .xsession-errors has grown too large, that has happened to me at one time. When it grows very fast, it doesn't roll over like its suppose to.
Updating to 4.7 might fix a lot of things, but it won't fix a problem that has nothing to do with KDE.

Once I put the kde repo file in the right place do I need to then add it to yum's config?

Shouldn't KDE be up to date anyway as long as I keep up with system updates?

Once you have put that file in /etc/yum.repos.d then all you should need to run is yum update to get KDE 4.7.

The Fedora KDE SIG has decided that KDE 4.7.X won't be an official update to Fedora 15 so if you want to stay up to date with the latest KDE in Fedora 15 then you will need something like that kde repo.

Awesome, thanks guys!

Update in process. I'll let you know how it goes.

So it seems like it was working properly before I updated KDE actually. I think a prior system update fixed it. But the KDE update went well and nothing broke.

Thanks again!

Great to hear that all went well :)

cancel that still having lag time issues when loading and using dolphin.

I think I found the culprit though.

When I run dolphin from the terminal it reads:


Advanced probing on /dev/sr1 failed while reading block size

I'm going to try and figure out what sr1 is and why it's failing while reading block size.

Can anyone point me in the right direction?

/dev/sr0 is the DVD or CD Rom drive

looks as if my fstab is missing an entry for my optical drives.


UUID=226c1694-9159-4e46-89c5-e856bd55ffae / ext4 defaults 1 1
UUID=464de46d-9ee2-480c-9b15-201f2d2394ec /boot ext4 defaults 1 2
UUID=d7cc5f62-6c51-41ed-9b56-871bf6efb8ca /home ext4 defaults 1 2

UUID=b5b585d2-2112-407a-8bc6-d7304da83681 /var ext4 defaults 1 2
UUID=d7e3d67c-30a1-4b33-bb1a-fdf0ce45ccef swap swap defaults 0 0
none /proc/bus/usb usbfs devgid=501,devmode=664,nodev,noexec,nosuid 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0


how do I go about adding an entry so that it is able to mount my DVD and CD drives and have them function properly?

Basically how do I figure out the UUID of the drives or do I even need that info?

Thanks,

I am going to mark this as solved because I figured out that the problem only takes place when an audiocd is loaded into my cdrw drive.

Still doesn't solve the problem I'm having. I feel like dolphin should be able to function normally when an audiocd is in the drive. I'll be opening a new thread on this soon.

Thanks for the help everyone.
