I have an acer aspire 5720, and have same issue.
I don't use acer-wmi.
I use standard acpi video module, and now it doesn't work
nothing in /sys/class/backlight, and this in dmesg:

[  211.907597] ACPI: Failed to switch the brightness (using hardware
keys)

This is when I try to change brightness, and this on module load


> [ 1910.228636] ACPI Error (video-0537): Current brightness invalid [20090320]
> [ 1910.229006] input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A08:00/device:34/device:35/input/input9
> [ 1910.390188] ACPI: Video Device [VGA] (multi-head: yes  rom: no  post: no)
>

Best regards,
