Hi all,
I'm trying install krita 2.7.2 on ubuntu gnome 13.10... I've tested without the backports ppa of kde enabled, but the result is always the same: krita opens only from terminal with 'sudo su'.
I've tried install krita via ubuntu central software (first time in a new box installation), with synaptic reinstall krita... after I've include the backports ppa... the message with normal user via terminal is:
===

Someone can help me?
thanks.

Did a window open and show a backtrace? If so we need that to see what's happening.

Hi,
Well, I've a new install and I verified the executable previleges for all kde and krita files. I've applied chmod o+x in all folders of krita... but it seems isn't here the problem.
Now I've open krita as root, I've an small draw and used some brushes presets and finally save as krita doc, the messages in my terminal are:

I've croped some warnings of same kind.
If you open as normal user krita via terminal the program close simply and the errors are on my first message.
Is possible, via terminal have more informations of krita while opens with normal user?

I've installed in the same box (ubuntu gnome 13.10) the kde-plasma-desktop.
Reinstall krita on kde desktop and the error is the same.

Try to look for a krita-debug or krita-dbg package and install it if it exists. Then, run "gdb krita", type "run", and when it crashes type "backtrace". Post the result here, please.

Greetings,
Sven

Hi,
the packages that you've mentioned don't exists on ubuntu-gnome repositories.
But gdb is already installed.

At a hunch, it looks like your normal user has got a broken .gih file installed. Try moving away .kde/share/apps/krita and restart. If that works, I'd be very interested in that .gih file.

Hi Boundewijn,
thanks of tip... I've move all my gih brushes in other folder and krita is open with normal user
I've made some tests with my dynamic brushes made for gimp... some of these brushes are a bit complex (1 or more dimensions) others not.
This is the link for my collection: http://code.google.com/p/forks-and-dril ... loads/list
I'm interested to understand the differences between the dynamic brushes of gimp and krita... it seems that krita has only 1 dimension, is it correct?
The brushes that were in the .kde/share/apps/krita, that caused the crash you can download here: http://forks-and-drills.googlecode.com/ ... hed.tar.gz
On the archive.tar.gz the series centipede-5* are saved on krita.
The original forks-jag_wet-centipede-5.gih have 10 layers, 2 dimensions [5(Random), 2(velocity)], 128x128px,
I don't know the reason... but this series it seems broken...

---
Do you have some documentation about which .gih kind is supported on krita?
--
thanks

Krita shouldn't crash on any .gih, of course. These are the gimp parasites we support on load:

constant, incremental, random, pressure, angle, tiltx, tilty

We can only create brushes that have constant, incremental, random, pressure and angle parasites.

In general, creating animated brushes in Krita is a bit underdeveloped, probably because most people use presets with the all the other dynamics.

Thanks,
About the dimensions... the .gih brushes can be made with until four.
How krita sees the .gih brushes with 2 or more dimensions?

Judging from the code... I'd say we support all of them. But I see very few gih brushes in real life, so there might be issues. It needs testing.

int chooseNextBrush(const KisPaintInformation& info) const {
quint32 brushIndex = 0;

for (int i = 0; i < m_parasite.dim; i++) {
int index = selectPre(m_parasite.selection[i],
m_parasite.index[i],
m_parasite.rank[i], info);

brushIndex += m_parasite.brushesCount[i] * index;
}
brushIndex %= m_brushes.size();
return brushIndex;
}
