if you think this is a polkit issue, you should tell us what version of polkit you have installed. mea culpa. polkit-0.98-1.fc14.x86_64 Does gnome-power-backlight-helper hang if you run it as root, like this ? /usr/sbin/gnome-power-backlight-helper --set-brightness 4 on subsequent run. I do something interesting. gpm helper app crashes. # pkexec /usr/sbin/gnome-power-backlight-helper --set-brightness 5 ** GLib:ERROR:gvarianttypeinfo.c:186:g_variant_type_info_check: assertion failed: (0 <= index && index < 24) Aborted (core dumped) (In reply to comment #5) > # pkexec /usr/sbin/gnome-power-backlight-helper --set-brightness 5 > ** > GLib:ERROR:gvarianttypeinfo.c:186:g_variant_type_info_check: assertion failed: > (0 <= index && index < 24) > Aborted (core dumped) What version glib2? Does this still happen with a fully up to date F14 system? Not reproducible any further. |
