Since a recent update, I see the bug on an IBM T41. On "gnome-power- manager --no-daemon --verbose" it outputs:
[gpm_brightness_lcd_init] gpm-brightness-lcd.c:496 (16:17:54): Laptop panel levels: 134648572 *** WARNING *** [gpm_brightness_lcd_init] gpm-brightness-lcd.c:498 (16:17:54): Laptop panel levels are invalid! (gnome-power-manager:6019): GLib-GObject-CRITICAL **: g_value_set_uint: assertion `G_VALUE_HOLDS_UINT (value)' failed [gpm_brightness_lcd_get_hw] gpm-brightness-lcd.c:116 (16:17:54): GetBrightness returned level: 0 Looks like the number of levels is bogus. This value seems to originate in the Hardware Information, where under "Generic Backlight Device" laptop_panel.num_levels already shows "134648572 (0x80692fc)". I'd expect something like "8" or "16". -- Laptop brightness on battery power doesnt work https://bugs.launchpad.net/bugs/136693 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
