Sometimes if left alone, it enters something like sleep mode. The only way to wake it up is toggle screen mode from GUI to Terminal, and then back to GUI. Do this by CTRL-ALT-F1, then CTRL-ALT-F8. Not sure if due to Mint, the motherboard, or the USB thumbdrive the system is fully installed to (not LIVE USB type install).
Can't seem to create links placed in Desktop folders to files or folders located on other media. In Windows this is possible and if the media is not present, the link not currently valid, a message informs one of it. Can not Linux do the same?
