Title:
8086:0046 [Acer Aspire 5742] Screen brightness not working
Status in linux package in Ubuntu:
Expired
Bug description:
My laptop does not respond to the screen brightness control after default
Ubuntu install. The following workaround worked: http://askubuntu.com/a/450594
It adds a config file to /usr/share/X11/xorg.conf.d/
adding acpi_backlight=vendor to boot params did nothing
adding acpi_osi=Linux to boot params only fixed the keyboard shortcuts, but
the screen indicator and the brightness settings dialog stopped working.
Please let me know if this is not the right package, or if you need
more info.
