Distribution Specific Notes

Ubuntu

With the current kernel (2.6.20-15), sound does not work in Ubuntu. You can download these files and copy them to /lib/modules/2.6.20-15-generic/kernel/sound/pci/hda/ to get sound working. It should be fixed in later kernels.

Summary

The installation of Linux on the Samsung R20 was a very easy exercise without any unexpected issues encountered at all.
