Dolphin locking up my Computer.

[Raydog]

I cannot access my Root file system in Dolphin.

If I click on my hard drive under Devices, click on Root under Places or click on / in the Location Bar it locks up my Macbook and requires a hard shut down.

I can move the pointer but can't select anything with it or use my keyboard.

I tried to open Dolphin using kdesudo Dolphin but it does the same thing. Any ideas?

Edit- I forgot to say that I applied the updates for Maui and thought that  that had broken something, so I did a fresh install and it turned out not to be the case. I'm at a lose.

Sounds very strange. How about get a listing in the terminal with ls /?
Does it show anything or freezes?

Do you experience any other lockups when doing heavy tasks on the harddrive/ssd?

[Raydog]

Here is the result from ls /. No other lockups. Thanks for the response.

Code:

bin   etc         initrd.img.old  lost+found  opt   run   srv  usr      vmlinuz.old
boot  home        lib             media       proc  sbin  sys  var
dev   initrd.img  lib64           mnt         root  snap  tmp  vmlinuz

Very strange indeed then.
Can you start dolphin from the terminal and see if it throws any error there.
Also check the ~/.xsession-errors file for dolphin logs.

[Raydog]

I can open Dolphin from terminal. If I try to open it as root (using kdesudo dolphin I get an error "the process for the file for protocol died unexpectedly".
At least it didn't freeze.

I opened ~/.xsession-errors , did a search for Dolphin and found no errors.

Just to clarify: I can open anything in my Home folder, the freeze happens if I try to open anything outside Home. Very strange indeed.

[leszek]

Yeah opening it up with kdesudo is not supported really. We have added the open with root actions contextmenu for that matter.

So opening up dolphin in terminal and going to your / (root) does not freeze it then?

[Raydog]

Yeah opening it up with kdesudo is not supported really. We have added the open with root actions contextmenu for that matter.

I can't get to any thing out side my Home folder to open as root with root actions.

So opening up dolphin in terminal and going to your / (root) does not freeze it then?

No, any attempt to access anything outside my Home folder immediately freezes.

Very frustrating.

OK, I just rebooted using the iso USB stick and there is no problem with Dolphin there.
Could it be a permissions problem? How would I find out?

Linux noob.

[Raydog]

I created a new user and Dolphin is fully functional.
Since it's early on I think I'll just start over.

User manager in the new user does not see my old user. How can I delete the old user?

[leszek]

You can use the userdel command as sudo/root user and give it the name of the user to remove.
