Keyboard not working in Citrix Receiver for Linux – a workaround

In technological terms, this is an amazing time to be alive.
In many ways, the advances in computing over the last 20-odd years have changed the way we live.
The specific advance that concerns me in this post is the ability to securely and remotely connect from my computer at home, to the computer in the office.
These days, remote working of this nature often requires the Citrix Receiver to be installed on the client machine – i.e. the one I’m using at home.
In my case, this machine is almost certainly running a Linux OS.
This shouldn’t be a problem. After all, the Citrix Receiver is available for Linux. However, as with any application available on multiple platforms, any bugs may be specific to an individual platform.
I was reminded of this recently. Whilst my Windows and Mac using colleagues were able to use the Citrix Receiver with no problems, I found the lack of a working keyboard when connecting to my work machine something of a handicap.
What follows is a quick overview of the symptoms I experienced, together with the diagnosis of the issue. Then I go through the workaround – i.e. uninstalling the latest version of the Receiver and installing the previous version in it’s place.

Resolving Hardware Issues with a Kernel Upgrade in Linux Mint

One evening recently, whilst climbing the wooden hills with netbook in hand, I encountered a cat who had decided that halfway up the stairs was a perfect place to catch forty winks.
One startled moggy later, I had become the owner of what I can only describe as…an ex-netbook.

Now, finally, I’ve managed to get a replacement (netbook, not cat).

As usual when I get a new machine, the first thing I did was to replace Windows with Linux Mint…with the immediate result being that the wireless card stopped working.

The solution ? Don’t (kernel) panic, kernel upgrade !

Support for most of the hardware out there is included in the Linux Kernel. The kernel is enhanced and released every few months. However, distributions, such as Mint, tend to stick on one kernel version for a while in order to provide a stable base on which to develop.
This means that, if Linux is not playing nicely with your Wireless card/web-cam/any other aspect of your machine’s hardware, a kernel upgrade may resolve your problem.
Obviously it’s always good to do a bit of checking to see if this might be the case.
It’s also good to have a way of putting things back as they were should the change we’re making not have the desired effect.

What I’m going to cover here is the specific issue I encountered with my new Netbook and the steps I took to figure out what kernel version might fix the problem.
I’ll then detail the kernel upgrade itself.
