If you use AppArmor (which is enabled by default on Ubuntu), you will also need to add permission for qemu to access the memory file in apparmor. This can be done by adding '/dev/shm/looking-glass rw,' to the /etc/apparmor.d/abstractions/libvirt-qemu file

;NOTE: The most common compile error is related to backtrace support this can be disabled by adding the following option to the cmake command. '''-DENABLE_BACKTRACE=OFF0''', however, if you disable this and need support for a crash please be sure to use gdb to obtain a backtrace manually or there is nothing that can be done to help you.
Should this all go well you should be left with the file '''looking-glass-client'''. Before you run the client you will first need to configure either Libvirt or Qemu (whichever you prefer) and then set up the Windows side service.
The memory size (show as 32 in the example above may need to be adjusted as per [[Installation#Determining_Memory|Determining Memory]] section.

If you want clipboard synchronization please see [[FAQ#How to enable clipboard synchronization via SPICE]]
