I suspect there are few of hot pixels on my panel. As it is still under warranty and by the rules of my vendor I can replace a machine if panel has a 3 dead pixels on it, I'd like to check how many dead pixels there actually are. In Windows, there are plenty of simple applications that just fill the whole screen with different colors so hot/dead pixels are easily visible. Does something like this exists for Ubuntu?
I'm getting a lot of

messages in my syslog, about 10 every second. That just makes syslog unusable, can I somehow get rid of them?
I don't know and don't really care about the reason of those messages being there, partly because my motherboard doesn't have pcie slots on it and partly because everything I care about works perfectly. That might be a WiFi chip I disabled in bios but hey, I don't want wifi to be powered on, I'm not using it.
So can I just suppress those messages?
I have noticed, that although my "Bluetooth Headset" works perfectly fine, buttons on it, like Previous, Next, Play etc do not.
Why is that?
For my work I need to stay close to 2.8 version of llvm (not yet released). I found out that Maverick will have it installed and already have some prepackaged version.
Is there a way I can use just this packages (and all the packages it depends on) in my current Ubuntu installation? Some kind of repository maybe?
I'm trying to move to grub2 and while chainloading from legacy grub works fine, I'm not sure how to move completely. Old grub was installed in boot sector of swap partition, /dev/sda3, and was working fine there. I want new grub to be installed there as well but during upgrade-from-grub-legacy it suggest to install at MBR or at ubuntu root partition, /dev/sda4. How do I force it to install at /dev/sda3? Can I just do grub-install '(hd0,3)' instead of upgrade-from-grub-legacy?
