When Launching Looking Glass the Desktop Doesn't Appear
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- **Using an AMD GPU?**
|
|
|
|
- After the end of the Radeon HD Series AMD started incorporating a
|
|
feature into their GPU's that effectively puts the card to sleep
|
|
when no display is connected. For this reason one of two
|
|
conditions need to be met.
|
|
|
|
#. The GPU needs to remain plugged into a monitor (this is good for
|
|
testing & troubleshooting).
|
|
#. The GPU needs to have a plug like the ones used in GPU Crypto mining
|
|
installed to trick the card into thinking that a display is
|
|
connected.

The Clipboard is not Working
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
- **Did you enable it?**
|
|
|
|
- Before you can Copy/Paste content between the Guest and the Host
|
|
you must `Enable Clipboard
|
|
Synchronization <https://looking-glass.io/wiki/FAQ#How_to_enable_clipboard_synchronization_via_SPICE>`_
|
|
|
|
- **Did you install the Spice Guest Tools?**
|
|
|
|
- Before you can Copy/Paste content between the Guest and the Host
|
|
you must install the `SPICE Guest Tools
|
|
driver <https://www.spice-space.org/download.html>`_. The
|
|
download is labeled as "spice-guest-tools".
|
|
|
|
.. warning::
|
|
|
|
**NOTE: Do make sure that you do NOT install the QEMU Guest
|
|
Tools driver. These are not the same.**
|
|
|
|
- **Did you install them twice?**
|
|
|
|
- The Spice VDAgent is available in both Spice Guest Tools, and
|
|
standalone as a separate installer. Check your installed programs
|
|
and uninstall the VDAgent if it's installed separately.

Depending on your distribution, various circumstances can cause Looking
|
|
Glass to still not run. Below is a list of known issues that can prevent
|
|
Looking Glass from running properly.
|
|
|
|
AppArmor
|
|
^^^^^^^^
|
|
|
|
AppArmor is a security application that can prevent Looking Glass from
|
|
running. How to add security exceptions may vary on your distribution:
|
|
|
|
Start by opening the file ``/etc/apparmor.d/abstractions/libvirt-qemu``.
|
|
Now locate and edit the following lines to represent how they appear in
|
|
the example:
|
|
|
|
.. code:: text
|
|
|
|
# for usb access
|
|
/dev/bus/usb/** rw,
|
|
/etc/udev/udev.conf r,
|
|
/sys/bus/ r,
|
|
/sys/class/ r,
|
|
/run/udev/data/* rw,
|
|
/dev/input/* rw,
|
|
|
|
# Looking Glass
|
|
/dev/shm/looking-glass rw,
|
|
|
|
Save, exit, and restart AppArmor:
|
|
|
|
.. code:: text
|
|
|
|
sudo systemctl restart apparmor
|
