Description of problem: Using nvidia driver, with a GTX460m. This laptop is the not-so-high grade G53J, with the screen : 1356x768'' On a fresh installation of FC14 with KDE, brightness controls works ( both fn keys and power manager appears as working, and everything seems okay in /sys/class/backlight/acpi_video0/ and /proc/acpi/video/GFX0/LCDD/, the values are okay and change accordingly). However, in reality, brightness is stuck at approximately 75% of max luminosity, and will not change. I also added the following section in /etc/X11/xorg.conf.d/00-system-setup-keyboard.conf : Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Before, when trying to increase brightness over approximately 75% resulted in the brightness moving back on forth around this value without being able to exceed it (on "paper", the brightness was also stuck in reality). I found this bug : https://bugzilla.redhat.com/show_bug.cgi?id=646322 However, I cannot load thinkpad_acpi. su -c 'modprobe thinkpad_acpi' Password: FATAL: Error inserting thinkpad_acpi (/lib/modules/2.6.35.10-74.fc14.x86_64/kernel/drivers/platform/x86/thinkpad_acpi.ko): No such device su -c 'modprobe thinkpad_acpi force_load=true' Password: FATAL: Error inserting thinkpad_acpi (/lib/modules/2.6.35.10-74.fc14.x86_64/kernel/drivers/platform/x86/thinkpad_acpi.ko): Invalid argument Version-Release number of selected component (if applicable): nvidia driver version : 260.19.29 kernel : 2.6.35.10-74.fc14.x86_64 How reproducible: Always Steps to Reproduce: 1.Install FC14 on the same laptop. 2. 3. Actual results: Brightness cannot be changed. Expected results: Brightness can be changed. Additional info:
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
