<div dir="ltr"><div>Hi! </div>On such strange moments I recommend to do fsck -fy of all filesystems, then verify all system files with <a href="http://manpages.ubuntu.com/manpages/hardy/ru/man1/debsums.1.html">debsums</a>: <ol><li>sudo apt-get install debsums</li><li>sudo debsums_init</li><li>sudo debsums --all --changed </li><li>collect the list of packages with missed files, then reinstall them manually with apt-get install --reinstall ...

I rebooted Monday morning and found that my desktop had been massively modified with no warning. * My bottom bar disappeared * Places disappeared from the top bar * Buttons on windows changed such that there was only a delete button * With the bottom bar gone, I lost my usual desktop selector. There may be other things but those are the primary ones. I certainly did not expect any such change in an LTS. Is there any way I can either back out these changes or repair the damage? The unexpected and unwanted UI change is driving me nuts and having significant impacts on my work productivity.
