Title: [power]: gnome-settings-daemon crashed with SIGSEGV in gnome_rr_screen_get_dpms_mode() Status in “gnome-settings-daemon” package in Ubuntu: New Bug description: Insert the installation usb key to my machine, and go to the live session(choose Chinese as the installation language and then click "try ubuntu" ). open the firefox, terminal ... in the live session, they all work well. and then click install ubuntu 12.10 icon on the desktop, and then some error appears. I noticed that there are some similar bugs existing, but I prefer file it here due to the installation language is not the same, and the hardware is not the same .... we can mark it duplicated if needed in the future.
