This happens on both Ubuntu 13.10 Unity, and Ubuntu GNOME. It use to happen on Kubuntu, but the ".config" settings have solved it. No more gliches on Kubuntu 13.10 at all.
With Ubuntu 13.10 Unity, the Launcher and Panel are "rainbow" colored and completely cover up Launcher & Panels. The background is normal. The Launcher flashes for a breif second so I see the icons, but then the "rainbow" color covers it up. With Ubuntu 13.10 GNOME, it is random when it freezes. I can ALWAYS cause it to freeze if I start Empathy. Various programs can cause it to freeze but not always. Empathy will always freeze the computer, and cause the screen to have unrecognizable virtical lines. A power off is the only option, That "elephant" nonsense doesn't work here. I know its the "GeForce 6150SE nForce 430" graphics that's causing this, because if I use "nomodeset" nothing freezes. With Kubuntu, when it first started freezing, I could use "modeset=0" and it would work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1181902 Title: Nouveau driver glitch on Ubuntu 13.04 will cause system to freeze under certain conditions Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: Hi, This only happens to Ubuntu 13.04, as my GeForce 6150SE card was working fine for Ubuntu 12.10. The Nouveau driver glitch will cause my whole system to freeze under certain conditions. I first get my system freeze when starting virtualbox, which is installed from the offical Oracle virtualbox PPA. Duplicated several times -- Freshly boot into X, then start virtualbox from within xterm via "virtualbox &", 2 seconds later my whole system freeze up. Google search indicated that it might be cause by the offical Oracle virtualbox PPA, so I followed the advice to switch to the offical Ubuntu virtualbox from the software center, but get into system freeze doing exactly the same thing. Duplicated several times as well. I was about to conclude that it is the virtualbox's problem when I suddenly remember that I've got into such system freeze before doing something entirely different, because the symptom is exactly the same. So I tried again -- "startx -- :1" to get me into another X session, and quit. Yes, then and there, I get into such system freeze again. The symptom is that the display turned black, then a random pattern tiled across the whole screen. Installing the closed source additional driver (nvidia) to replace the Nouveau driver solve the problem, which in turn proved that my suspicion was right -- it *is* the Nouveau driver that is causing the problem.
