Same here. How do we change the stepping of screen brighteness thingie in X11? Text mode goes correctly from 0 to 8 here, but gnome changes it steps of 2.
Thanks. ** Package changed: ubuntu => gnome-power-manager (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/1000270 Title: Laptop backlight brightness increases/decreases 2 steps each time Status in “gnome-power-manager” package in Ubuntu: New Bug description: Hi, I have a Lenovo 3000 N200 laptop which uses a Nvidia Geforce Go 7300 graphics chip. I noticed this issue in Lubuntu 11.10 with the Nvidia binary driver and also after booting a Xubuntu 12.04 CD (using the Nouveau driver there I think). As far as I can remember, this issue wasn't present with either Ubuntu 8.04 or Xubuntu 9.10. The laptop has 8 possible backlight brightness settings. At the desktop, increasing or decreasing brightness (by pressing Fn-F10 or Fn-F11) causes the brightness to increase or decrease by 2 steps instead of 1. However, in text mode -- after switching with Ctrl- Alt-F1 -- changing brightness works as it should, in single steps. I noticed that the page http://forum.notebookreview.com/acer/434638-linux-acer-1410-1810tz-1810t.html mentions a fix for a similar issue with Acer laptops. That fix adds a line to /etc/rc.local: echo N > /sys/module/video/parameters/brightness_switch_enabled Applying that to my laptop fixed the screen brightness double-stepping at the desktop, so now changing brightness works as it should. However after doing that, the brightness cannot be changed at all when in text mode.
