x11-drivers/nvidia-drivers-169.07 supports xorg brightness control, too.
"Brightness controls (Alt F10,F11) are hard wired, but only have effect while in text-mode, or using xorg-vesa- or xorg-nv-driver. While researching, I found some info from that seems relevant: It’s worth mentioning that even though the brightness controls did not work while in X, they nevertheless did work after changing to a text TTY. After finding this thread I tried again with 313.30, and the brightness controls work again. In both cases my brightness control did not work. I updated the nvidia-drivers package to 331.20 and then 325.15. I’m running Gentoo with xorg-server-1.14.3. I’m using a Lenovo T61p with a Quadro FX 570M. Let me chime in with what appears to be the same problem. So it looks like a regression for the 319.12 version specific. Just installed this version 313.30-0ubuntu1~xedgers~raring1, with that version the brightness controls are working like it should.

I am going back to a previous version now, because I can’t work without having those controls working, but I am perfectly able to test some things out if asked, a reboot and a reinstall of the driver is done in a minute.

With the 304.x and 310.x drivers the controls were working fine.ĭISTRIB_DESCRIPTION=“Ubuntu Raring Ringtail (development branch)” Or maybe someone else will show up with a better solution.I am using Ubuntu 13.03, with the latest xorg-edgers ppa installed.Īnd just installed the latest NVidia binary driver trough the repository.Īfter a reboot, I found out that my brightness controls are suddenly not working anymore. For instance, on my ASUS laptop I counted 8 things that work in Ubuntu and don't work in pclos (but I managed to set some workarounds for some of them). use Ubuntu (or the LXDE flavour of Ubuntu) or Windows. You can use sections 2 and 3 from my howto as hints for setting up key bindings use xrandr and bind multiple keys for multiple brightness values (I had the impression that xrandr can't do it incrementally like xbacklight does so you need more keys for more values). try another video driver, maybe this way you'll be able to adjust brightness the hardware way with xbacklight (well, good luck with that)

So, since only xrandr works for you (and xbacklight doesn't), it means that ATM you can adjust brightness only the software way, so you have a few solutions: Tion, if your hardware has support to actually change theīrightness, you will probably prefer to use xbacklight. However, this is a software only modifica‐ Multiply the gamma values on the crtc currently attached to the The xbacklight command only works as far as changing the value of the parameter, nothing happens with the screen.īy the way xbacklight does not seem to be present in the older versionś root commands. (Changing to US international doesn't make any difference.) I also checked the keyboards in PCC, in both cases it's the same: US keyboard type generic 105-key (intl) PC. It seems as though something is not hooked up right! When I go back to the old 2010.12 live disk - the one that does allow brightness control - I do get XF86MonBrightnessDown/Up with F4/F5. The others do nothing, the key-press is not recognised. Similarly F2, F3 & F10 give XF86WLAN, XF86Battery & PRINT. Got proprietary Nvidia drivers installed by Ubuntu itself, graphic card is recognized well by the system yet brightness control does not work when adjusted by either FN + F5/6 shortcut or by dragging brightness slider manually (keyboard shortcut triggers slider move as well, so it's heard by the system). Xbindkeys -k doesn't do anything with most of my FN keys in the latest version, but F1 gives Thanks omnio, I don't know too much about the "innards", but you had me exploring.
