I seem to have some issues with my ubuntu 11.10 installation.
Firstly, I cannot change the default wallpaper. The screen comes up, everything works as excepted, except that it doesn't actually make the change. Next time I open up the dialog, it is as if nothing happened. It doesn't matter if I log in using GNOME, GNOME Classic, Unity or Unity 2D.
I also installed the System Load Indicator (which shows the CPU usage, memory, network, etc, in nice mini-graphs in the top panel). However, upon the next log-in, this goes back to default settings.
Some other things I've noted:
If I change the UI theme to for instance Radiance, this actually changes the theme, and is saved between sessions. However, the Appearance dialog fails to recall what the current setting is, and defaults to "Ambiance".
[Update]: In gnome tweak tool. I've changed the Default, Document, Monospace and Window title font size. Weirdly, the only change remembered is the Window title font. If I change any of the other sizes, close the gnome-tweak-tool, re-open it, it's back to the default values, except for the Window title font.
[Update]: The preferences in nautilus are not stored.
If anyone knows what could be the problem, and if the two I mentioned could be related to each other, I'd be happy to investigate. Might there be a folder or file with incorrect permissions?
Thank you for taking the time to read this. I'll keep adding more observations as I find them.
I never figured out how to resolve the issue, and eventually gave up and did a clean install. I still don't know what I did to mess it up the first time, so I can't really post and accept an answers. My suspicions is having done a manual install gtk+ and glibc-2.30.2.
