Description of problem: Laptop Toshiba Satellite T110-107 I believe this is related to bug 702352. I'm using Fedora KDE 19 but have seen the same issue on Ubuntu using Unity and Enlightenment as at Thursday 01/08/13 (two days ago). The brightness keys are recognised but screen brightness is always max (unless screen is off). Changes to brightness through graphical menu in system settings > power management has no effect but the slider is movable and the box displaying the new brightness percentage is rendered. Version-Release number of selected component (if applicable): Linux 3.10.4-300.fc19.x86_64 #1 SMP Tue Jul 30 11:29:05 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux How reproducible: Attempting to change brightness either with keyboard Fn keys or using graphical menus. Steps to Reproduce: 1. Press key 2. Observe brightness 'bar' render and animate 3. Observe no change to screen brightness Actual results: Screen brightness does not change Expected results: Screen brightness should change Additional info: # pm-utils-bugreport-info.sh SUSPEND LOG cat: /var/log/pm-suspend.log: No such file or directory ====== SYS POWER total 0 -rw-r--r--. 1 root root 4096 Aug 3 10:50 disk -rw-r--r--. 1 root root 4096 Aug 3 11:53 image_size -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_async -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_freeze_timeout -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_print_times -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_test -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_trace -rw-r--r--. 1 root root 4096 Aug 3 11:53 pm_trace_dev_match -rw-r--r--. 1 root root 4096 Aug 3 11:53 reserved_size -rw-r--r--. 1 root root 4096 Aug 3 11:53 resume -rw-r--r--. 1 root root 4096 Aug 3 10:50 state -rw-r--r--. 1 root root 4096 Aug 3 11:53 wakeup_count ====== SYS POWER STATE freeze mem disk ====== SYS POWER DISK [platform] shutdown reboot suspend ====== QUIRKDB Kernel modesetting video driver detected, not using quirks. location: /usr/lib64/pm-utils/video-quirks total 88 drwxr-xr-x. 2 root root 4096 Aug 1 21:39 . dr-xr-xr-x. 7 root root 4096 Aug 1 21:39 .. -rw-r--r--. 1 root root 5338 Jul 1 15:34 20-video-quirk-pm-acer.quirkdb -rw-r--r--. 1 root root 899 Jul 1 15:34 20-video-quirk-pm-apple.quirkdb -rw-r--r--. 1 root root 4259 Jul 1 15:34 20-video-quirk-pm-asus.quirkdb -rw-r--r--. 1 root root 5942 Jul 1 15:34 20-video-quirk-pm-dell.quirkdb -rw-r--r--. 1 root root 3671 Jul 1 15:34 20-video-quirk-pm-fujitsu.quirkdb -rw-r--r--. 1 root root 10798 Jul 1 15:34 20-video-quirk-pm-hp.quirkdb -rw-r--r--. 1 root root 3911 Jul 1 15:34 20-video-quirk-pm-ibm.quirkdb -rw-r--r--. 1 root root 3680 Jul 1 15:34 20-video-quirk-pm-lenovo.quirkdb -rw-r--r--. 1 root root 11584 Jul 1 15:34 20-video-quirk-pm-misc.quirkdb -rw-r--r--. 1 root root 943 Jul 1 15:34 20-video-quirk-pm-samsung.quirkdb -rw-r--r--. 1 root root 2289 Jul 1 15:34 20-video-quirk-pm-sony.quirkdb -rw-r--r--. 1 root root 4133 Jul 1 15:34 20-video-quirk-pm-toshiba.quirkdb ====== SYS PROPS system_firmware_version: V2.60 system_firmware_vendor: TOSHIBA system_firmware_release_date: 04/21/2010 system_hardware_vendor: TOSHIBA system_hardware_product: SATELLITE T110 system_hardware_version: PST1AE-00K00GEN system_board_product: SATELLITE T110 system_board_version: Not Applicable system_board_vendor: TOSHIBA system_hardware_primary_video_vendor: 0x8086 system_hardware_primary_video_product: 0x2a42 system_hardware_primary_video_driver: i915 system_hardware_primary_video_using_kms: true system_kernel_version: 3.10.4-300.fc19.x86_64 ====== QUIRKS USED --quirk-no-chvt ====== ETC PM /etc/pm: total 12 drwxr-xr-x. 2 root root 4096 Jul 8 09:56 config.d drwxr-xr-x. 2 root root 4096 Jul 8 09:56 power.d drwxr-xr-x. 2 root root 4096 Jul 8 09:56 sleep.d /etc/pm/config.d: total 0 /etc/pm/power.d: total 0 /etc/pm/sleep.d: total 0 DIR /etc/pm/config.d ====== DIR /etc/pm/power.d ====== DIR /etc/pm/sleep.d ====== UNAME Linux localhost.localdomain 3.10.4-300.fc19.x86_64 #1 SMP Tue Jul 30 11:29:05 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux ====== RPM kernel-3.9.5-301.fc19 kernel-3.10.3-300.fc19 kernel-3.10.4-300.fc19 pm-utils-1.4.1-24.fc19 package hal is not installed package hal-info is not installed package gnome-power-manager is not installed package vbetool is not installed package radeontool is not installed package hdparm is not installed ====== FEDORA RELEASE Fedora release 19 (Schrödinger’s Cat) ======
I have the same problem on Asus Zenbook UX31A It works fine on kernel 3.9 (just keyboard backlit that doesn't work) but on 3.10.4-300 , brightness adjustment through FN key doesn't work also and it set the default brightness to 0 (black screen) after enter gnome login screen.
