Hi, after reading the summaries of Asus UX31E and UX32VD i did some testing of FreeBSD on an Asus UX31A: Hardware -------------- Intel Ivybridge CPU + graphics Centrino(R) Advanced-N 6235 WiFi USB 2.0 + 3.0 Realtek Cardreader (Product-Id 0x139) Software ------------- - FreeBSD-CURRENT (svn274583) - acpi_asus_wmi & acpi_asus loaded - xorg-7.7 - xorg-server-1.16.1 - Mesa 10.3.2 - xf86-video-intel-2.99.916 Results ---------- - F1: Suspend function key works - F2: WiFi function key does not work - F3/F4: Keyboard brightness control works - F5/F6: Display brightness control does not work - F7: Display on/off works - F8: not tested - F9: not tested - F10: Volume on/off does not work - F11/F12: Volume control works - Suspending works - Resuming: - i915 only - no display after resume - acpi_video loaded before i915kms: - no display after resume - acpi_video loaded after i915kms - display coming back, but display brightness after resume is lower although hw.acpi.video.lcd0.brightness reports the same value - Display brightness control partly works - sysctl hw.acpi.video.lcd0.brightness=X works - function key changes the brightness, but only allows to switch between brightness levels 1 and 2. - changing the brightness level from 100 to 30 reduces the power consumpion from 11.5mW to 8.8mW. - with i915.7 patch (http://kib.kiev.ua/kib/drm/i915.7.patch) - display coming back (with and without acpi_video) - Display brightness control does not work (neither with nor without acpi_video) - WiFi (Intel 6235): works - CardReader (Realtek Product Id 0x139): does not work Open questions ----------------------- - How to automatically load acpi_video after i915kms? - How to enable presetting the display brightness? - How to enable a smooth function key based brightness setting? - Is there any hope for the card reader? - There have been several mailing list threads in the past but it seems they all ended up without conclusion. Regards, Lutz
