I booted with acpi_backlight=vendor and the Fn+F8 and Fn+F9 keys worked as expected to control the internal laptop screen brightness. But there was a side effect: now, plugin the external VGA does not change to external screen automatically anymore. And after manually changing to the external VGA in KDE and removing the VGA cable does not change back to the internal laptop screen automatically. I hope there is a way to keep Fn brightness keys working and the automatic screen selection, simultaneously.

I installed linux-headers-3.11.0-4, linux- headers-3.11.0-4-generic, linux-image-3.11.0-4-generic and linux- image-extra-3.11.0-4-generic from Saucy packages repository but the problem persists. When trying: $ xev | sed -n 's/^.*state \([0-9].*\), keycode *\([0-9]\+\) *\(.*\), .*$/keycode \2 = \3, state = \1/p' keycode 36 = (keysym 0xff0d, Return), state = 0x10 keycode 232 = (keysym 0x1008ff03, XF86MonBrightnessDown), state = 0x10 keycode 233 = (keysym 0x1008ff02, XF86MonBrightnessUp), state = 0x10 Event codes appear correctly. And changing: /sys/class/backlight/intel_backlight/brightness changes the brightness of the screen, but pressing the key combination does not. I believe this happens because the key combination is, in fact, changing the value of /sys/class/backlight/acpi_video0/brightness I have http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu http://ppa.launchpad.net/bumblebee/stable/ubuntu in my package sources Thanks! --- ApportVersion: 2.9.2-0ubuntu8.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: silvio 2689 F.... pulseaudio /dev/snd/pcmC1D0p: silvio 2689 F...m pulseaudio /dev/snd/controlC0: silvio 2689 F.... pulseaudio DistroRelease: Ubuntu 13.04 HibernationDevice: RESUME=UUID=58f7acf2-4914-4b11-a2ac-e641cb4b39fd InstallationDate: Installed on 2013-08-18 (57 days ago) InstallationMedia: Kubuntu 13.04 "Raring Ringtail" - Release amd64 (20130424) MachineType: Notebook W350STQ/W370ST MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.11.0-9-generic root=UUID=f0bca002-701a-49bb-befc-7343bac2e245 ro locale=pt_BR quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.11.0-9.16-generic 3.11.2 RelatedPackageVersions: linux-restricted-modules-3.11.0-9-generic N/A linux-backports-modules-3.11.0-9-generic N/A linux-firmware 1.106 RfKill: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no Tags: raring Uname: Linux 3.11.0-9-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lp lpadmin plugdev sambashare sudo vboxusers dmi.bios.date: 04/11/2013 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 4.6.5 dmi.board.asset.tag: Tag 12345 dmi.board.name: W350STQ/W370ST dmi.board.vendor: Notebook dmi.board.version: Not Applicable dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: Notebook dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr4.6.5:bd04/11/2013:svnNotebook:pnW350STQ/W370ST:pvrNotApplicable:rvnNotebook:rnW350STQ/W370ST:rvrNotApplicable:cvnNotebook:ct9:cvrN/A: dmi.product.name: W350STQ/W370ST dmi.product.version: Not Applicable dmi.sys.vendor: Notebook To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1218547/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
