Note: A very similar device (ASPIRE 5736Z-4085, look up the entry) has been reported that comes with a Broadcom Corporation BCM43225 wifi card which does NOT work with free software.I notice that it was working perfect with this videocard with some old trisquel version. However, at Trisquel 5.5 and 6 appeared a problem which left the screen black. nomodeset kernel parameter was leaving the computer usable, but aspect relation was erroneous and it was a pain to watch the screen. I found a solution. Use the parameter "acpi_osi=" and increase brightness pressing brightness buttons after grub and the light will be returned returned. I'm using succesfully this on Trisquel 6.0 and I can use the laptop comfortably and with 3D acceleration.
