Added upstream Gnome.org bug ID in "See Also". (Hope I put it in the right place.) Upstream they asked me to run xbacklight (which is not installed in Fedora by default, but IS available as a yum package. (Thank you koji packageinfo and auisl!)) This may be a kernel driver problem because when one uses xbacklight to VIEW the display brightness the brightness is CHANGED to be the complement of what it was. As I said in my upstream report: I think I see the problem.... Is xbacklight -get supposed, ever to CHANGE the backlight value? To attempt your test, I ran xbacklight in an xterm window, just before attempting to enter the power management control panel. Basically, every time I run xbacklight, either with no arguments or with the -get argument, it sets the backlight value to the complement of what it was. IE: $ xbacklight 11.000000 $ xbacklight 90.000000 $ xbacklight -get 11.000000 $xbacklight -get 90.000000 If the library call to get the value is changing the value, from no matter where you issue the library call, that would tend to create problems. Good news! I just took updates today and with the 3.11.1.-200 kernel, the problem is fixed. Now calling xbacklight -get only gets and does not set the brightness. |
