delete not working

[garyartista]

I am using gimp 2.8 on Ubuntu 16.04 with a Wacom Tablet.  The problem is that even after reinstalling Gimp the erase key fails to work.  It continues to paint, say, and refuses to switch to erase.  I can make text boxes and use other tools but the program refuses to switch to erase.  If I change the file .gimp2.8 to gimp2.8delete or something and reinitiate Gimp, erase works for a few minutes and the problem returns.  The problem occurs whether I use the tablet or the mouse.  Any thoughts?

welcome to gimp-forum.net

Not much point reinstalling Gimp. Which version have you installed? The stock 'buntu 16.04 is Gimp 2.8.16 but there is a Gimp 2.8.22 from a PPA that is worth upgrading to.

You have already tried the usual 'disable' the Gimp profile advice. Very strange that the mouse is also affected. Never come across that one before.

Which Wacom tablet are you using? The mouse and tablet settings are held in the file ~/.gimp-2.8/devicerc delete that to reset all the settings. Before that, what does that file show for the tablet stylus settings

example, this on my Kubuntu 16.04 + ancient tablet.



Maybe someone can spot something.

My Gimp version is 2.1.16 I'll try the .22 to see if that helps. Intuos pen small CTL 480. Thanks for any additional suggestions

After deleting the device files I have so far been able to work with only one minor difficulty. In one of the color choosing modes the color would not change. I Switched to another mode and the color changed.

[rich2005]

A couple of things.

The listing you give is for the core pointer, there should be entries for the tablet as well that might show some strangeness, but I would leave that for the moment apart from looking in the Edit menu -> Input Devices where there should be something like this screenshot: https://i.imgur.com/Z5e1HaQ.jpg

What it does show is the 'bluetooth mouse' Assuming the tablet is regular USB. Have you tried using a regular USB mouse in place of the bluetooth? The problem might be hardware related.

For Ubuntu (and associated such as LinuxMint) you need to add a PPA. That gives Gimp 2.8.22

see: https://launchpad.net/~otto-meier/+archive/ubuntu/gimp there is information on the page for enabling it.

My setup in input devices is like what you posted. I upgraded to 2.8.22 and ran across the same problem but was able to get it to resume working properly by closing and reopening gimp. I will play with it more today and see how it goes. Thanks for the advice!

Still having the same problem. Closing and reopening Gimp did not help, disabling and reenabling the tablet and stylus. I have disabled and re-enable the mouse, using it in both modes. I am getting 2 copies of devicerc. when I renamed them just now the problem disappeared.

Open Windows>Dockable dialogs>Device status. This will opend a window showing your which tools is associated with which pointer. You will normally see the "core pointer" (that lumps together the non-pressure devices: mouse, trackpad, trackpoint...) and the two stylus ends (since you have a Wacom, I assume it is double-ended so you distinct device for each end of the stylus).

Now, if you hit the Shift-E (which is what you mean by "Erase key"?) does the tool of any device changes?

[garyartista]

The devices are working correctly at the moment. When I click on the eraser tool. or any other, it shows up in the device status. I'll take note of what happens when the problem recurs.

OK, remember that the Tool must be activated with the very device you are going to use it with (you can't select the Eraser with the mouse to use it with the stylus). And normally, keyboard shortcuts should set the tool for the currently active device. It is possible that if the stylus is too high above the tablet, this disables the stylus and (temporarily) activates the "core pointer", which therefore is the one that will receive the tool change.

[garyartista]

Everything worked fine for about two hours then the troubles returned. I have removed the device file twice. Now when I erase I no longer get white, I get a checkered background. I created the file I am working on to fill with a white background. I do not know how to change that or even if it is possible. Odd.

I fixed that with Edit, Preferences, Display, Check Style- white only. Have no idea how this changed.
