No brightness steps with Thinkpad Z61m in Gnome
Last modified: 2007-10-31 00:37:30 UTC
Alpha1 + Alpha2/3 updates Description: I cannot change brightness in small steps on my Thinkpad Z61m in Gnome How to reproduce: If I press Fn+Pos1 brightness goes to max and if I press Fn+End brightness goes to min without any steps - see screenshots. ouput of powersave -L: Available brightness levels: 8 In Ubuntu 7.04 brightness levels do work in Gnome - not perfectly but I have a few steps between min and max.
Created attachment 134448 [details] Brightness goes directly to min if pressing Fn+Pos1
Created attachment 134449 [details] Brightness goes directly to max if pressing Fn+End
I suspect two applications catching the same button event and changing the brightness at the same time. gnome-power-manager and the gnome-mixer-applet (whatever it is called exactly) for instance. Does 'powersave -k u' (brightness up) and 'powersave -k d' (brightness down) work correctly? Anyway, the powersaved doesn't change the brightness. That's either the hardware itself or the gnome desktop.
> Does 'powersave -k u' (brightness up) and 'powersave -k d' (brightness down) work correctly? Yes, that works without problems - there are 8 steps available from 0 to 7.
Could you try running - "killall gnome-power-manager" "gnome-power-manager --no-daemon" then try adjusting the brightness. Are you getting output similar to - "GLib-GObject-CRITICAL **: g_value_set_int: assertion `G_VALUE_HOLDS_INT (value)' failed" ? if so see - https://bugzilla.novell.com/show_bug.cgi?id=310273
No response in several weeks. Going to presume this is a dupe. *** This bug has been marked as a duplicate of bug 310273 ***
