Hello everyone,
I'm new to the forum. 

I'm having some problems with GIMP 3.0.4 (Flatpak) installed today on my PC with Linux Mint 22.1 Cinnamon.
Until two days ago, I had version 2.10.36-3ubuntu0.24.04. However, since yesterday I have been unable to use it: when creating or opening an image, the various mouse cursors (brush, selection, etc.) remain confined to the left side immediately after the toolbar and there is no way to do anything. After searching in vain, I purged GIMP (sudo apt-get purge --auto-remove gimp) and installed the Flatpak version.

Now, these are the problems I have: 

1. When I went to Edit>Preferences>Folders>Brushes, I saw that there are 2 folders, but when I try to open them, it tells me that the folder cannot be found. The folders indicated are these:
   /home/franz/.var/app/org.gimp.GIMP/config/GIMP/3.0/brushes
   /app/share/gimp/3.0/brushes
   I went to check and, indeed, under the folder /home/franz/.var/app/org.gimp.GIMP/config/GIMP there was nothing, all the various folders were missing, i.e. there was no /3.0 folder and all the subfolders /brushes /filters /fonts /plug-ins etc.! So all the other various preference folders do NOT actually exist (!?); 
   
2. When I try to put a new brush in the brushes folder indicated by the programme (see above), it does not exist when I reopen Gimp. It should be noted that, since the folder did not exist (see point 3 above), I created the /3.0/brushes folder myself, but, as mentioned, even if I put new brushes in it, they are not recognised.
   
3. When I right-click on a layer, all the icons are missing from the list that appears. Have they perhaps been removed in the current version?
   

When working with Gimp's histograms, you always have the choice of whether you want to display the x-axis linearly or non-linearly. 

When working with python the function to get the histogram values has no paramter for the x-axis e.g.
t, mean, std_dev, median, pixels, counter, percentile = layer.histogram(Gimp.HistogramChannel.VALUE, 0.5, 0.6)
returns the values using the non-linear x-axis. 
In contrast the function to change the histogram e.g.
t = layer1.curves_spline(Gimp.HistogramChannel.VALUE, curve)
calculates the spline on the linear x-axis.
I found this out by comparing the values with the manually created values in Gimp.

I need a possibility to gett the correction by spline on the non-linear x-axis.

Is there a way to achieve this?

Hi!
I would like to crop an image by entering the values in the crop dialog box.
The values I'm looking for is Position X/Position Y and Size X and Size Y.
These values describing the cropping area and should be enough but:

- when I try to enter values in the corresponding fields, my image is zooming. Regardless if I use the NumPad or the normal numbers. I'm not able to input the numbers.
  What is the way to enter the value fields and be able to put numbers in it? 

- when I was able to somehow enter those numbers I can't see a way to execute the crop. When I click in the image, it will reset these values.
  How do I actually initiate the crop after I entered the values?

All the tutorials in the net show the interactive way to crop but I could not find any that shows how to do it just by numbers.

Thanks for any suggestion.

Hi there, ive installed the 3.0.0 version but i cant use the dynamics thing. It works in the previous versions.

...for ubuntu 22.04 / 24.04 / equivalent Mint.

On my cloud storage gimp_304_deb.AppImage about 97 MB 
https://u.pcloud.link/publink/show?code=...T6WXijSh2V

Comes with installed gimp_gmic_qt 3.5.4 (remember QT5 is required) and resynth-heal plug-ins.

Edit:  An update to gmic plugin 3.6.1
https://u.pcloud.link/publink/show?code=...WRUVuJAzNk
Download unzip and put the gimp_gmic_qt folder in your user plugins folder (it will supersede the old version) 

It has some failings, python is a bit old.  The usual guarantee - there is none

It's said inpainting may be used to repair a damaged photo. G'MIC has 5 different inpaint routines. Between them they have about 2 dozen adjustable parameters. I can't find any basic instruction. Why 5 separate inpaint routines? What are all the parameters for? If anyone could advise a beginner, or point to such advice, it would be appreciated.

Hi

I've been trying to start GIMP with a custom set of fonts, separate from my system, so I've been using a custom fontconfig path, with fonts.conf being:

Hi, newbie to Gimp here. Does anyone know if it's possible to undock the image window while Gimp is in single window mode? 

I'm not a fan of floating windows, I want it to be like Photoshop where it's a single window for the app but having the option to undock the image window as I need to drag it my 2nd monitor for ref when working on an image in the 1st monitor.

As far as I can tell I seem to be only able to undock the image window when not in single window mode.

Hello everyone!  I'm new to Gimp!  Been using Corel Draw for over 20 years now and am retired from the graphics field. I'll be 70 in July so be gentle with me please! I'd like to get to know how to use Gimp to pass my time and have been watching videos on how to do things.  I'm very excited to try my luck with Gimp.  I've started by downloading Gimp 3.0.2 and wanted the G'mic and Resynthisizer plugins too.  Well That didn't go to well. I'm not sure if these are compatible.  Neither plugin works on my Windows 11 PC running a Intel Ultra 9 processor with 32 gig of ram.  I've followed the videos from downloading to installing and everything seems to go well but when I try to access the plugins they are not there in filters. Soooo, I'm here to learn as much as I can from all of you.  Please don't yell at me for posting this if it is in the wrong place...just point me in the right direction please.  Thanks Robbie
