BTW, when I exit to console using Ctrl+Alt+F1 and then execute "echo -n 1 > /sys/class/backlight/acpi_video0/brightness" or "echo -n 30 > /proc/acpi/video/C14B/C15F/brightness"
all works fine. It seems to me that my Function keys (Fn+F9/F10) work fine and pressing them changes the brightness value correctly, but I feel that this value isn't read in GNOME by some other module that operates a backlight lamp or something like this. Outside the GNOME it all works fine. I don't know if it is a GNOME issue or X server issue or what else it can be -- Backlight brightness problem on HP Compaq 8710p https://bugs.launchpad.net/bugs/308784 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
