Hello, are you talking about the graphical user interface, or the tty/text modes? I use a Focus 40-blue only with tty modes so far and have no real problems, except that line-down is sometimes treated as line-up, however I am in no way sure that this is a brltty problem. With kind regards, Henk. Kristoffer Gustafsson schreef op 4/7/2014 7:24 PM:
