Comment 41 for bug 1264795

I've used Ubuntu 16.4 in variuos computer mainly hp g4 250 without any problems. No I'm using the Aspire 5 A517-41G-7161 and I got the problem . Its particularly annoying because the applications switcher pops up randomly and lasts on the screen for a few seconds. The solutions here proposed are too technical for me to access. I need a more easy explanation if there is someone that have solved the problem. It's a pity, after so many years where I've been using Ubuntu, I'm thinking to migrate somewhere else.
