mitochondrion Hi! There is something strange with screenshot taking shortcuts. Only the combinations that save the screenshot to the "Pictures" folder seems to be working. Sometimes when I try to take a screenshot using the crtl + print combination (the stock one for saving a screenshot to the clipboard) it saves the screenshot to the Pictures folder.
Justin I'm assuming you're using Budgie, if so it is a conflict between keyboard shortcuts as mentioned. There is a Budgie Screenshot Applet available that is amazingly functional and has shortcuts to allow you to upload to image sharing websites as well.
