kde/qt3-applications freezing (kile, k3b, opera, qtconfig-qt3,...)

Asked by andog

I'm having a problem on my machine with some applications: k3b, kile, opera,
qtconfig-qt3,... They start up and freeze as soon, as I'm performing the first
actions (e.g. on opening a file the dialog comes up, but I'm not able to select
anything before freezing).

I find interesting, that other users on my system don't have this problem.

So far I tried to delete ~/.qt/ and ~/.kde/.

I tried to completely remove libqt3-mt and all depending
applications (k3b,...) and reinstall.

Repairing broken packages removed slocate and updated some language-packs, but nothing more.

I don't want to delete all config-directories from my home-directory, so has
anybody an idea, what I could try next?

Could it have to do something with the uninstallation of scim?

Ram? is the linux-swap partition switched off on your user?

no, swap partition is small, but switched on

The swap partition should be between 1xRam to 2xRam although if you don't use hibernate mode and do have plenty of Ram then it shouldn't be much of an issue. Going into hibernate mode copies the contents of Ram into the swap-partition but the rest of the time the swap is just used as a buffer for ram to use when it has stuff that its not using right away but might need access to in a hurry.

Basically i can't see why you are having this problem. I thardly seems fair that it's only your user account that is suffering from it on this machine. Have you tried setting up another user and tried switching to using that instead? Sorry, it's not an elegant answer, hopefully someone will give a better ansewr soon.

Good luck and regards form

The size of the swap partition to be twice the size of RAM I heard is now obsolete and having 4 GB of RAM and not using hibernate, I think it should not be the problem.

The problem is not obvious for me either. I am thinking, it could be some side-effect of removing scim.

The thing with the user accounts is reasonable, because I carried the same home directory from ubuntu 5.10 to 6.06 to 7.10 and now 8.10, but the other users are empty accounts.

Switching to a fresh home directory is shurely the fastest solution, but a bit nasty, as long as I don't want to lose all settings of the programs.

The other reason the solution is important for me, is the curiosity which side-effect causes hanging qt3.

Solution:

scim and qt. I just wanted to reinstall scim, when i noticed there is a package regarding scim and qt:

scim-qtimm: SCIM context plugin for qt-immodule.

removing this package solved the problem :-)

thank you for your help!

lol, brilliantly solved there. Nicely done :) I'm glad you dodged the new-user approach too, i wasn't happy with that plan. I think hibernate mode is worth avoiding but some say it really helps cut down on power-consumption, i think they miss out the power used during shutdown tho as this takes a lot longer for hibernate mode.

Anyway, congrats and nicely done :)

I don't want to fight the drawbacks of hibernate on a fully encrypted machine ;-)

Is there any special reason you mentioned swap-space?

cheers

Not really but if Ram+Swap=VeryLowNumber then that could lead to slow downs. Seems like you have plenty to spare tho :)

ok, but who really wants to run kde(libs) on such a system ;-)

lol, you'd be amazed at some questions in here - and thinking back, some of the crazy things i tried in first couple of months too :)
