I have an Acer Aspire One HAPPY-2DQuu with a croatian keyboard. After installation of stable the keyboard doesn't work properly. Some keys like 5 and 9 don't work at all. This is the case wheter I select the generic 105 keys keyboard or the acer laptop keyboard and with all available croation option. How can I solve this? How can I read out how the actual device identifies itself? Thanks in advance!
