Phil, this has been going on since the first days of December, not just a couple of days. Google it, riot police is very brutal, beating people up, men, women, lying on the ground or no, armed or no, peaceful or no.
I've installed KDE desktop alongside Pantheon. A big mistake, as it turned out... Now many of my apps are visually broken: Chromium, code::blocks for example. My desktop fonts are changed and other stuff. I could try and purge the ppa, but I'd really like to try out KDE for some time and VM is not really an option. Please help guys... :(
