My os version is Ubuntu13.04, today, after started and logined, my desktop freezed. But i can still start the software in the left launcher.
I reveive a system bug report that the /usr/bin/gnome-screensaver is crashed.
Then, i start the terminal, and try to start the screensaver.
gnome-screensaver
i got these error:
(gnome-screensaver:): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.background' does not contain a key named 'draw-background'
After google for a while, i found these solution.
sudo vim /usr/share/glib-2.0/schemas/org.gnome.desktop.background.gschema.xml
add the code as below
<key type="b" name="draw-background">
<default>true</default>
<summary>Have file manager handle the desktop</summary>
<description>If set to true, then file manager will draw the icons on the desktop.</description>
</key>
then restart the glib-compile-schemas
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
replace the unity
unity --replace
It is ok now!
By the way, before google for the solution below, i also fix the bug of brightness & lock
errors:
(gnome-control-center:): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.screensaver' does not contain a key named 'show-notifications'
Trace/breakpoint trap (core dumped) (gnome-control-center:): GLib-GIO-ERROR **: Settings schema 'org.gnome.desktop.screensaver' does not contain a key named 'ubuntu-lock-on-suspend'
Trace/breakpoint trap (core dumped)
solution:
sudo vim /usr/share/glib-2.0/schemas/org.gnome.desktop.screensaver.gschema.xml
add these code
<key type="b" name="show-notifications">
<default>true</default>
<summary>dummy summary</summary>
<description></description>
</key>
<key type="b" name="ubuntu-lock-on-suspend">
<default>true</default>
<summary>dummy summary</summary>
<description></description>
</key>
then
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
Have fun with Ubuntu
