Hello all.

Just joined and wonder if anyone has found a work-around for the "little green circle mouse droppings" issue with the latest Linux Kernel ATI mobility drivers, and GIMP 2.4+?

I ran a few searches but they returned nothing, so I'm sorry if this has already been coverd, and I missed it.


Thanks,


Dan

never heard of that...do you mean that mouse movements left artifacts on the opened imagines ?

if so what happen if you save and reopen the images with the green circles, are visible on the saved imagine?

and may be useful more details (wich distro you use on what kind of computers and so on)

TangledWeb,

This won't help much, but I recall the issue years ago using GNU/Linux. What you would get was like a trail left over when you would move your mouse cursor across an Image window open in Gimp. I don't know if you ever notice, but if you switch to a different screen or workspace and then return to the workspace Gimp is on, the trail disappears. Let me do some research, I think the issue was even discussed here on gimptalk some months ago. I have not had the problem for a long time. I can't recall if I had to set my screen size to correspond with my monitor settings or exactly what. But I recall having that problem, finding a solution, fixing it, and since it has been years, forget the fix at this time.

Until I can research it and find the answer, maybe someone else will read this and have faced the same issue recently and know the fix off hand. Fortunately for me, it has been years since I had that issue, so long that I had forgotten the fix, lol. I'll make an effort to search for a fix for ya. In the mean time, please continue to do some searching in your GNU/Linux distro forums for answers, or even post the problem there and someone may provide an answer for you sooner there.

:h:

[highlight]Update[/highlight]: I found one link discussing the issue here:

It still doesn't sound familiar to the fix I used years ago, but throwing it out for your review.

While I have never experienced this problem, I seem to recall it having cropped up during the 2.3 development cycle (around version 2.3.12). The problem was owing to graphics acceleration and, on Windows, the workaround was to disable acceleration in the hardware setting.

Perhaps you could try using the VESA driver and see if that corrects the problem.

Afternoon, guys.

Thanks so much for the rapid response!

Ayup. Just moving the mouse across the open document while a drawing tool has been selected, but without clicking any mouse buttons, leaves trails. They are not visible in the saved product, and any action which requires a screenwrite will temporarily erase them, so they don't get saved to the work, but seeing through them while working is an issue. In particular, and in general, the computer(s) are either HP or Compaq laptops in the ze-4000-5000 series. The offender seems to be the ATi Radeon Mobility drivers. I've tried a dozen or so recent distros and the problem is evident in all of them, so it's a FUBAR between the newer GIMPs and the newer Linux kernels.

(ccbarr) Ayup! That's the critter, alright.

(saulgoode) Ayup! That's when it cropped up. In fact, I filed a bug report with the GIMP developers, and got a rather curt response that it was the driver's fault, then the discussion that followed indicated the change in the GIMP was a difference in a reference color for the non-active brush. (I have filed bug reports with both the kernel devels and the GIMP devels. Each is pretty sure it's the other guy's problem. : )

Sooooo. I'm down to scrounging for work-arounds. :w:

[highlight]UPDATE:[/highlight] Oddly enough, by some experimenting this morning on another project, (F8 fedora Compiz-fusion installation) I found a solution. Once the Compositing driver for Compiz-fusion is running ... the problem disappears! Soooo. Even though I don't usually run the eye candy, (slows the system down) it does fix the problem.

[SOLVED!]

Thanks again, guys!
