This started to happen to me yesterday, but I don't hive a high end system: it's a Intel(R) Pentium(R) Dual CPU E2160 @ 1.80GHz with a normal hard disk (not SSD)
When staring gnome-settings-manager from the console to solve it, I see this warning: oleg...@moria:~$ Unable to find a synaptics device. ** (gnome-settings-daemon:2019): WARNING **: Got less number of items in credentials hash table than expected! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/574296 Title: Gnome theme not applied on session start -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
