problem with paintbrush
Hello all,
I have just started using Gimp, switching over from Photoshop. I have two problems:
1.The paintbrush and fill tool do not seem to work. I suspect I accidentally changed a setting someplace and this is the result.
2. The cpu usage is at about 1,000,000 by the time Gimp has started. There are pauses and sometimes freezes when I'm working.

Any help is appreciated!
Thanks

RE: problem with paintbrush
When tools don't seem to work there are usually two causes:

1) you have a minute selection somewhere (remove by Shift-Ctrl-A)
2) you are actually painting somewhere else (another layer below is selected, or a channel is selected). Make sure your layer in selected in the Layers dialog (Ctrl-L)

Another cause, but unlikely if this happens to several tools, is that the tools are in a mode that have little effect on your layer ("below" mode for instance).


About the CPU, it's hard to tell... Gimp can get slow if you have added very many fonts/brushes but since you are a newcomer this is unlikely. Did you install any plugin? What process is burning the CPU? Gimp itself of something else (see your system task manager/process monitor) ? For further guesses please tell us which Gimp version and which oiperaing system you are using.

If you think you have altered a setting and can't find how to back it out, you can make Gimp recreate a new profile for scratch. Locate your Gimp profile and rename it (to ".gimp-2.6.disabled", for instance). Gimp will create a new one with default settings when you restart. You can later copy back carefully useful things from you prevoius profile (brushes/gradients/scripts...)

RE: problem with paintbrush
Thanks for your suggestions, I removed the Photoshop Brushes I had added from the brush folder and Gimp opened up right away, no problems with it getting stuck etc.

I checked that nothing was selected, checked I was on the right layer, and still the brush and fill do not work. Actually, the brush DOES work, it is just that it shows up way to the left of where I click it. When I try the Fill there is a little circle with a slash (can't use) that shows up.

I didn't quite understand how to find the Profile and make changes to it. I went to the file/preferences and found the folders. There are two boxes that can be checked, on all of them the top box is checked and the bottom one is not.

Thanks for your help!

RE: problem with paintbrush
Are you using a Photoshop brush or a regular Gimp one? I have never seen such an offset in the brush, unless you are using the Clone tool by mistake...

The "forbidden" sign in the icon for the bucket-fill tool shows up because you are cliking in a place where the fill won't happen. Two examples:
  • You asked for "fill selection" but are not clicking inside the selection
  • You have selected a layer which isn't the full image size and are clicking outside that layer.
There are likely a couple more cases. If this doesn't explain it, attach a screen capture with your image, the Layers dialog, and the Fill tool options. It is even better if you make a very simple image on which you can reproduce the problem (attach the XCF of that image, too).

There is a link in my previous post to another thread explaining where your Gimp profile is (for Windows & Linux). The two folders you see in almost each category of Edit/Preferences/Folders are normally one located in the general Gimp installation (not writable) and one in your Gimp profile (writable). As such they are a good way to locate your Gimp profile, which is the parent folder of the writable ones. Their "writability" is only useful when you save things to them (gradients, brushes...), and when you have several "personal" folders.
