i've updated my system from ubuntu 12.04 to ubuntu 12.10.
Now i can't use the R tool : pick color. The only color i have is black !
Do you know this trouble ?
Yeah, it happens on other OSes too. Under Linux it might be due to variations between window managers, or even hardware variations. Are you using Unity, and what graphics hardware does your computer use?
It's one of those eternal cyclic bugs. People complain they can't pick any colour off the screen, and that's useful so we change the implementation so they can
do this, which is susceptible to the problem you're seeing; people complain again so we change it back to only being able to pick from the canvas; back to step 1.
Anyway, we should probably make a workaround for people having this issue: meta-bug at https://gna.org/bugs/?20311Edit:
