VMWare currently has the best VDI experience with their Pcoip technology.   A windows client is readily available but not a linux client.
VMWare does sponsor the openview client OSS project, but it does not have support for pcoip (only rdp).  So thats not a good option.
Fortunately there is a completely unsupported workaround! VMware does provide linux based clients to their thinclient partners and several of them have these downloads available.
These steps have been tested on Opensuse 11.4 (HP's downloads are deb based)
First:  Go to HP'ssupport and  download section for their T5565 thin client.  Here is the current link but this could change (google will find the latest link for you): http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=4306249&prodTypeId=12454&prodSeriesId=4306187&swLang=13&taskId=135&swEnvOID=4030
Second:  Download the "Thinpro Add-on Vmware view broker".  Current version is 4.6
Third: Download the "Thinpro Add-on Broker Update".  This has several dependencies you might need.
Now you can use a windows workstation or use wine to extract the exe's you just downloaded.  [...]

I've been running Opensuse 11.4 Beta fro some time now and needed to get the Novell client for Linux up and running.
Surprisingly it worked fairly well with only a few minor modifications.
Step 1: Download binutils-2.19-9.3-*.rpm
Step 2: Do NOT install the binutil. Instead open the rpm in your favorite zip program and extract the libbfd-2.19.so to your /usr/lib64 (/usr/lib for 32 bit users)
Step 3: Download NCL 2.0 SP2
Step 4: Mount the ISO and run the "ncl_install install" command
Step 5: Accept any warning about the missing libbfd requirement. You can just accept the option to "break" the rpm and install anyways.
That should be it! The only issue I still encounter is a message of "User.OU" is not a user object.
To get around this enter the username as user.context and leave the "context" field in the login dialog box empty. You might also need to use an IP address rather than a tree [...]

Ok, Suse Linux Enterprise Desktop 11 should be released anytime now.
Novell has already posted a preview version here: http://www.novell.com/promo/home/sneakpreview.html
I have access to the beta and have been running it on my primary laptop for about 2 months now. Most of the grips with my SLED10 install are now gone. Hiberbation works great, battery life is much longer etc.... But I was suprised at iFolder 3.7 client was nowhere on the DVD.
When I tried to install ifolder 3.7 it complained about deps. Some quick googling shows other having issues with it on Opensuse 11.1 (of which SLED 11 is based on).
I got it working and it was fairly simple. So here are the steps. This should work with Gnome and KDE. Of course, lets hope that Novell gets the iFolder 3.7 client updated by the time SLED 11 is official.
You will need to grab your iFodler 3.7 install from your OES [...]

Well, your running SLED 10 SP2 because it's the best corporate linux desktop around. SLED 10 SP2 only comes with GTK 2.8. Thats not a problem for most applications.
However, Firefox 3 is out and requires GTK 2.10.
So how do you get Firefox on your SLED 10 desktop? Well, it's not too bad.
You can build GTK 2.12 into a new directory structure and link Firefox 3 directly to it
These instructions are based off an excellent article over here: http://blogs.warwick.ac.uk/mikewillis/entry/of_firefox_3/
I've added the GTK engines to give firefox a more natural look. And I chose to build GTK and all the other libraries directly under firefox. We would not want to build and install GTK 2.12 into the normal paths becuase that would break alot. I've chosen to install them right under the firefox directory in a folder called opt. That way the entire firefox and all it's dependency are right in a [...]
