Fedora 17 USB Multiseat Compatible Hardware

Posted on 08. May, 2012 by in UD-160-M

The Plugable $50 thin client KickStarter project is growing.

But we need early adopters so we have people using the solution, finding and fixing problems, and helping to spread the word. What we deliver now might not include some KickStarter extras and will be higher priced than through the KickStarter project, but it will include all the components and will work with Fedora 17 Beta.

Hardware

Interested in getting your hardware now? If you’re in the USA, here’s what will work with Fedora 17 Beta:

Plugable USB 2.0 Universal Laptop Docking Station with DisplayLink DVI/VGA up to 1920×1080, Audio, Ethernet, and 4 Available High-Speed USB 2.0 Ports Product Details $79.00
Plugable DC-125 USB 2.0 Laptop Docking Station and Multiseat Thin Client – VGA up to 1440×900 / 1280×1024, Audio, 2 USB ports Product Details $64.95

Note the $79 version does not mention use as a thin client (it’s marketed for the laptop docking market), but it will work. And in the future and as part of the KickStarter project, we’ll have a UD-160-M model which is the same hardware, but with documentation tailored for the thin client / multiseat case.

International Shipping Options

If you’re outside the USA, we’re still working on expanding our options. Note that the UD-160-A is not sold on amazon.co.uk and the DC-125 sold there is not yet updated with Fedora support (we’ll let you know when it is).

So to reach the rest of the world, we’re offering a new option for international shipping of the DC-125 from the USA via USPS Flat Rate Priority. It’s the same price as in the USA ($64.95), but with an additional $16.95 shipping cost. Just visit the DC-125 page, and choose “more buying choices” in the lower right.

And look for the second option with “INTERNATIONAL SHIPPING AVAILABLE”.

Let us know if you have any trouble with payment through Amazon. This version of the DC-125 includes all the components purchased through normal channels, but without the extra color packaging — this is so it can fit in a $16.95 fixed-rate priority international shipping box.

If you’ve never ordered and had an item shipped from the USA before via the US Postal Service, please research the rules in your country. We declare the actual value of all items, so in some countries customs and/or VAT taxes are collected, and all of those are paid by the recipient once the items arrive in country. And also note that while every shipment will have a tracking number, the tracking is generally poor once the item has left the USA.

Software

You can download Fedora 17 Beta here. Must be the default version (GDM) and use the “install media” option at the top — live CDs don’t work yet because of the modifications needed.

Install F17 to the hard drive of an available machine. For 3-4 thin clients, you can use a spare older machine – we’d recommend a machine with 1GB RAM and 2 cores or 2 GHz or more, but anything that F17 will run on at all, will work.

The thin clients will only come up to a green screen at this point. A few pre-release fixes are needed:

  1. Disable SELinux. Here’s how. Things will work now, but with some plug/unplug instability. To fix that …
  2. Get our latest fixes in udlfb.
    • Get all latest fedora updates (so your kernel and kernel-devel headers are at the same version)
    • sudo yum install gcc kernel-devel
    • Get latest udlfb, compile and install. The following commands will do that: 
      git clone http://git.plugable.com/webdav/udlfb/
cd udlfb
make
sudo make install
sudo depmod -a
  3. make sure none of those steps reported errors (missing module dependencies are actually ok). Reboot.

Now, any Plugable UD-160-A/M or DC-125 thin client you plug in should automatically pop up a new login.

Comment here or email support@plugable.com if you have any trouble at all – we’d be happy to help! And thanks in advance to the early users who help find issues and spread the word about how cool this technology can be!

The $50 Thin Client

Posted on 01. May, 2012 by in udlfb

Imagine if you could easily share one computer with a whole class, your whole family, the whole office.

We believe this makes a lot of sense. It saves a lot of time and money. It lowers the environmental impact of computing.

The way we can make this truly compelling is with low cost USB thin clients and zero software licensing fees. So we’ve launched a KickStarter project to try to push this concept over the finish line.

We’d love to have you involved! Visit the Plugable Thin Client on KickStarter to learn more.

Mac OS X 10.7.3 Breaks Display Rotation

Posted on 16. Feb, 2012 by in USB-VGA-165

We recommend not upgrading your Mac to the OS X 10.7.3 release if you are using a Plugable graphics display adapter.

This latest upgrade to the Mac OS was made publicly available at the beginning of this month. Unfortunately it breaks display rotation functionality in all third-party display drivers.

DisplayLink, the maker of the graphics chipset in Plugable graphics display adapters, is in touch with Apple about potential fixes for the problem. When word of a solution arrives, we’ll post it on the Plugable blog.

Meanwhile, if you already have upgraded to 10.7.3 and now find that your rotated display connected throgh a third-party graphics display adapter seems to be broken, here are the steps posted in the DisplayLink Mac forum (http://displaylink.org/forum/showthread.php?t=1484) to restore functionality:.

1. Shut down the Mac.

2. Disconnect the Plugable graphics display adapter.

3. Boot in safe mode by pressing and holding the shift key after the startup tone (http://support.apple.com/kb/HT1455).

4. Open the Display preferences in System preferences.

5. Reboot.

6. Connect your Plugable graphics display adapter. The display should work again, and its rotation should be back to standard.

If you have upgraded to 10.7.3 but do not use display rotation, you might not see any problems. However, we still do not recommend updating to 10.7.3 until DisplayLink is certain that all display-management functionality is stable in this version of Mac OS X.

DisplayLink’s latest Mac driver works properly with OS X 10.7.2 and earlier OS X releases.

You can find the current DisplayLink driver for OS X at http://displaylink.com/support/mac_downloads.php.

If you’re having trouble with your Plugable graphics display adapter on a Mac, you can look to our support forums at http://support.plugable.com or write to us at support@plugable.com. We’re here to help.
