HALd Hangs When Starting On Gentoo
For the last couple of days I have been having a problem with the Hardware Abstraction Layer daemon version 0.5.9.1 on my Gentoo Linux installation. Every time I tried to start it, it would just hang for a long time without showing any output, until after a few minutes it just failed to start. After searching on the internet for a while, I found several other people that have the same problem but have not found a solution, and it seems that Ubuntu is experiencing the same problem.
Since this was a new installation, I decided to check the Gentoo KDE HAL guide to make sure that I did not miss anything. It turned out that I did not miss anything, and I even had inotify support enabled in the kernel. That can checked that by typing the following command:
gunzip -c /proc/config.gz | grep INOTIFY
If you see the following output, then everything is alright. The y can be replaced by an m, meaning that you chose to compile it as a module.
The next step was to see if hald is reporting any errors. This can be simply done by issuing the following command:
hald –daemon=no –verbose=yes
I found that the following error was being repeated over and over very fast, so if you see the same output read on to see my solution.
device_info.c:984: Unhandled rule (0)!
I am not sure which of the following commands solved it, but after I executed them all I no longer had any problems. I believe that the re-emerging of pciutils might have been the solution, because I remember that I originally left the zlib flag enabled, which is a big no-no if you want HALd to compile.
rm -rf /usr/share/hal/
emerge hal pciutils
