Also, this work around... I'm not so sure it's a good solution to

How do I get rid of an existing /dev/md0? I'm thinking that I can try creating a RAID1 array using the two allegedly good disks and see if I can make that work. If that works, I'll get rid of it and try recreating the RAID1 with one good disk and the one that mdadm thinks is faulty. Hopefully that will show me whether I have a hardware problem or a software one. Jeff

[gentoo-user] XFCE4 keyboard shortcuts not working

I don't know what keys correspond to XF86Display and Superp so I haven't tested those. The commands associated with the two shortcuts that don't work do execute successfully so I'm not sure what the problem is. Does anyone know how to fix this? - Grant

[gentoo-user] Linux Kernel 3.2.0 USB Mouse
Hi all, I'm trying to upgrade the kernel on my desktop from 3.1.6 to 3.2.0(-r1). Unfortunately, my Logitech USB trackball does not work in 3.2.0. It is listed in the lsusb output so it is being recognized but neither GPM nor X responds to it. I have tried to make sure that the .config files are as identical as possible. The differences that I see do not seem relevant to my problem. Any ideas? Cheers, Hilco
Re: [gentoo-user] [SOLVED] Init Scripts Not Starting
Alright, so... I haven't mentioned it up until now because I didn't feel it would have any bearing on the problem, but the installation in question is a VirtualBox guest operating system running on a Windows host. Since I didn't have any particular attachment to the installation, I decided to fdisk and start from scratch. I did this and got the barest most basic Gentoo installation up and running. After I had done this, I realized that I had forgotten to add net.eth0 to default. I did so, rebooted, and sure enough, net.eth0 did not start. I then went and meditated under a tree for a while, because it seemed the world had finally turned its back on me. After this, I said 'what the hell' and tried out a few things. One of the things I tried was to rebuild openrc. For whatever reason, this worked. I'm going to try this on another installation of VirtualBox on another machine and try to reproduce it, but I'm still a little in the dark. This installation was built using the latest minimal install iso, latest stage3 and latest portage snapshot.
