USB redirection issues

Wednesday, May 30th, 2012

If you enable USB redirection for Citrix XenDesktop, VMWare View, Fabulatech or Microsoft RemoteFX the rule to enable USB redirection in general does not mean that this will redirect all USB devices now. You need also to setup class rules (Printers, HID..) or device rules to get it working.


Configuring VMWare View Display settings

Wednesday, May 30th, 2012

If you want to setup the monitor configuration for VMWare View sessions, you need to configure this thru the RDP Global configuration in the IGEL Setup or UMS Profile. It’s not really clear and i noticed this today in a workshop, so a good reason to post it here.


Universal Desktop OS support for ATI Radeon HD 2400 XT

Friday, May 25th, 2012

We just tested a ATI Radeon HD 2400 XT with the IGEL Universal Desktop OS and it work perfectly incl. dual monitor support. The ATI Radeon HD 2400 XT is used with a regular desktop pc.

Requirements: Universal Desktop OS incl. Advanced Feature Pack and feature “Native graphic card driver support enabled”


IGEL UMD-Multimonitoring extreme or could I get one screen more please?

Friday, May 25th, 2012

Do you need a workplace with more then two screens… Maybe 3, 4 or up to 8. Then you should try the IGEL Universal MultiDisplay solution which is available now. The solution is quite new and IGEL provides a small data sheet here:

During my test with a trial version it works quite smart but i recommend to use a UD3 as satellite. Really a nice solution and much more flexible and cheaper then other available solutions. You can find the results from my first test’s here:

Minimum requirement is the Universal Desktop LX Firmware 4.09.200, a UD5 as master incl. the recommended network card (available in the starter kit), one or more satellit system’s (UD2,3 or 5) and a license from IGEL to enable the solution.


Fixing WiFi connection issues when using IGEL Universal Desktop LX / OS

Thursday, May 24th, 2012

If you run into WiFi connection issues try the following settings as add-on to your WiFi configuration. All settings can be found in the IGEL Setup / Profile -> System -> Registry -> network -> interfaces ->wirelesslan.

wireless_mode = IEEE 802.11 b/g = Try to setup the used channel if possible

Make alway sure that you setup the right regulatory domain and location in the regular wireless configuration in the IGEL Setup, this can also cause a lot of issues if configured wrong.



Webcam test in the IGEL Linux

Tuesday, May 22nd, 2012

If you want to check if a webcam works in general in the IGEL Linux, create a terminal session and start the session. Log in as root and type in/execute ls /dev/video* , the result should look like /dev/video0.

If you got no result the webcam will not work, if you got /dev/video0 type in: gst-launch-0.10 v4l2src device=/dev/video0 ! ‘video/x-raw-yuv,width=640,height=480,framerate=30/1’ ! xvimagesink and execute the command. If you have /dev/video1 or similar just change the command parameter to the right value. After the command is executed you should see the video picture from your webcam. Please note: this don’t mean the camera will work with Citrix, VMWare or whatever. This still needs to be tested but it’s a good indicator if the camera will work in general. If this fails, you can still try/use USB redirection of course.


Tip: IGEL Thin Clients don’t refresh there status in the UMS Console or don’t get a new configuration

Tuesday, May 22nd, 2012

Setup a DHCP Option 224 as string field or a DNS hostname “igelrmserver” which points to the management server. If using the DNS hostname make sure that the name can be resolved…

Make sure that the client-server communication port’s are open, see also

If using Linux based IGEL Thin Clients you can create a terminal session (IGEL Setup->Accessories) and after you start the terminal session use “ping igelrmserver” and “probeport +server name/ip+ 30001” to verify a working UMS connection. If using the DHCP option type in “cat /wfs/dhclient.leases.eth0”, you should now see the options provided by your DHCP incl. “option igelrmserver “+servername/ip+”;. If you can not read the servername/ip you have not used the string type for the DHCP Option 224 and you need to fix this in your DHCP Server configuration.


Official IGEL FAQ collections available

Monday, May 21st, 2012

Hello Folks,

IGEL got some new FAQ collections available on there download server, the downloads links:

German (2009):

These FAQ’s contain a couple of information’s like supported hardware, session improvements and are very useful. It’s funny that they’re currently not available at but i believe it will follow later.


Using Citrix VDI in a Box 5 with IGEL Linux clients (Firmware 4.09.100 or higher)

Saturday, May 19th, 2012


before the firmware release 4.09.100 it was only possible to use Citrix VDI in a Box 5 thru the XenApp configuration in the IGEL Universal Desktop LX/OS but not with the Firefox browser. Since the 4.09.100 you can also use the firefox browser but:

You need to enable a setting in the registry for this, it’s only mentioned with a short context in the release notes for the 4.09.100 firmware.

Open the IGEL Setup or the UMS profile and go to System->Registry and enable the setting browser_plugin.ica.vdi_fix.

After this configuration the VDI in a Box Webinterface works like a charm for the users.

Improve USB storage write performance

Saturday, May 19th, 2012

To improve the write performance for USB storage devices in general follow these steps:

1) Open the IGEL Setup or your UMS Profile and go to System->Registry
2) Disable devices.autofs.sync_option

Note: This will not work for “true” USB Redirection (View, XenDesktop, RemoteFX, Fabulatech and so on) but it will improve the general performance for RDP, ICA and other drive mappings. Test in advance!

Tip: Helpfull site to identify hardware based on chipsets

Monday, May 7th, 2012

Sometimes users have a problem with the IGEL Release Notes or Driver support, means you’re looking for a supported WiFi Device and you get a list with supported chipset’s. But how to find a device based on these chipsets? Quite simple, just look at .

Here you can search for a chipset and you will get a list with devices that are using the wanted chipset, like the Ralink RT2970:

Of couse you still need to test the device and nobody will take a warranty that this will work for you at all but it’s better then nothing.
