Notes
For the ATI Radeon Xpress 1250 graphic controller used in the R20 you have to use the X.org radeonHD driver included with most Linux distributions.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.Related Resources

Summary
The installation of Linux on the Samsung R20 was a very easy exercise without any unexpected issues encountered at all.Have you installed Linux on this laptop? If so how about leaving a comment about your success in the comments section below.

Any help?
As Basic as poss please.

Note:
If needed, aticonfig is a tool provided by the drivers that can configure your xorg.conf for you
Installation does not work on most Linux distros
The only version working is Knoppix 5.1
Kernel and acpi
ATI now works perfectly
The best for this laptop: Sabayon
Lot's of problems
Most of the distros I tried didn't even want to boot because they couldn't configure graphics (Sabayon was an exception). Finally got Ubuntu alternative to install and managed to install fglrx manually. It mostly suspends to ram, but cannot always wake up. Sometimes it crashes completely. Battery time in Linux is max 1 hr 20 minutes! No Compiz etc
Re: Lot's of problems
CD drive is easy to replace with slot load one (if necessary). Even marked, where to unscrew for this. (possible 2nd battery in DVD bay place?)
most of distros unaware about new PCI ID: 1002:7942 (ATI Radeon x700 compatible), that's why uncapable to show-up nice looking GUI (still no problem to install in text mode)
SATA is VIA compatible, so use that one if necessary.
Battery time in Linux is equal to battery time in Vista if not in "no-wireless/document only reading" mode
Fedora 7 and co-booting tips
I agree with you, Vista is absolutely diabolical running on this laptop, quite the very worst, slowest, easy-to-crash computer experience I have ever had, ever.
I am very glad to say that Linux works much, much better - Vista uses up almost 400megs of memory for instance and Linux needs less than 300.
To install Linux on this laptop but retain the option to co-boot into Vista (although I don't know why you'd want to!), set the partition size of the 'C' drive to the smallest possible (25 gigs) when you first start up the laptop. Samsung's setup software create another D partition in the remaining disk space.
Then completely remove the D drive - i.e unallocate the partition - from the Disk Manager in Vista. This should provide just enough space for Linux to install itself. I used a bootable Fedora 7 DVD.
FC3 ?
We have FC7 or 8 don't you think 3 is a bit old anyway?
I am sure 7 or higher will do fine.
I am at moment installing Opensuse 10.2 on it. bloody Vista is load of CRAP

Bottom line - the R20 may not work with older Linux distributions unless you can find the relevant hard drive drivers (I was trying Fedora Core 3 since that is the specified host environment for developing applications for an embedded Linux box I am using)
