Package: mate-power-manager Version: 1.8.1+dfsg1-1 Severity: normal Dear Maintainer,
On login, the LCD brightness is changed to the value in the Power Management Preferences, under the "On AC Power" tab. This happens not only on AC power (as expected), but also when running a laptop on battery power, which I would not expect (I would expect the value listed there only to be applied on AC power, not on battery power). Oddly, when changing the brightness slider in the settings ("Set display brightness to"), the new brightness is applied immediately when on AC power, but is not (immediately) applied when running on battery power. As a separate issue, but I'm mentioning it here anyway as it's related, there is no way to *not* change brightness when running on AC power on login (and, due to this bug, also on battery power). I personally prefer to set the brightness depending on the environment, not (normally) based on battery power. I can report a different bug for this if necessary, but maybe that feature is too close to the freeze to be added anyway. Here are my power management preferences: ~$ dconf dump /org/mate/power-manager/ [/] button-power='interactive' sleep-display-battery=600 brightness-ac=22.0 info-last-device='/org/freedesktop/UPower/devices/mouse_0003o046DoC52Bx0004' backlight-battery-reduce=false button-lid-ac='nothing' spindown-enable-battery=true info-stats-graph-points=true info-stats-graph-smooth=false action-critical-battery='suspend' button-suspend='suspend' info-history-graph-points=true info-history-time=86400 info-page-number=0 idle-dim-ac=false info-history-type='charge' idle-dim-battery=false button-lid-battery='suspend' info-stats-type='charge-data' info-history-graph-smooth=false icon-policy='never' By changing the "Set display brightness to" setting a few times and logging out and back in, I have confirmed it is really set to that setting. And it is that setting it is set to when it is on battery power as well. I have attached a screenshot of the Power Management Preferences window. -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16-2-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages mate-power-manager depends on: ii consolekit 0.4.6-5 ii dbus-x11 1.8.8-2 ii libatk1.0-0 2.14.0-1 ii libc6 2.19-11 ii libcairo2 1.12.16-5 ii libcanberra-gtk0 0.30-2.1 ii libcanberra0 0.30-2.1 ii libdbus-1-3 1.8.8-2 ii libdbus-glib-1-2 0.102-1 ii libfontconfig1 2.11.0-6.1 ii libfreetype6 2.5.2-2 ii libgdk-pixbuf2.0-0 2.31.1-2+b1 ii libglib2.0-0 2.42.0-2 ii libgnome-keyring0 3.12.0-1+b1 ii libgtk2.0-0 2.24.25-1 ii libmate-panel-applet-4-1 1.8.1+dfsg1-1 ii libnotify4 0.7.6-2 ii libpango-1.0-0 1.36.8-2 ii libpangocairo-1.0-0 1.36.8-2 ii libpangoft2-1.0-0 1.36.8-2 ii libunique-1.0-0 1.1.6-5 ii libupower-glib3 0.99.1-3 ii libx11-6 2:1.6.2-3 ii libxext6 2:1.3.3-1 ii libxrandr2 2:1.4.2-1 ii libxrender1 1:0.9.8-1 ii mate-notification-daemon [notification-daemon] 1.8.0-2 ii mate-power-manager-common 1.8.1+dfsg1-1 ii notification-daemon 0.7.6-2 ii policykit-1 0.105-7 ii systemd 215-5+b1 ii upower 0.99.1-3 ii xfce4-notifyd [notification-daemon] 0.2.4-3 Versions of packages mate-power-manager recommends: ii udisks 1.0.5-1+b1 Versions of packages mate-power-manager suggests: ii mate-polkit 1.8.0+dfsg1-4
