Troubleshooting ############### There are many different issues that can arise when setting up Looking Glass. Below is a list of known issues with potential solutions: .. _when_launching_looking_glass_the_desktop_doesnt_appear: When launching Looking Glass the desktop doesn't appear ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - **Using an AMD GPU?** - After the end of the Radeon HD Series, new AMD GPUs go to sleep when no display is connected. For this reason, one of two conditions must be met. #. The GPU needs to remain plugged into a monitor (this is good for testing & troubleshooting). #. The GPU needs to have a dummy plug installed which presents itself as a monitor. .. _the_clipboard_is_not_working: The clipboard is not working ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - **Is clipboard synchronization enabled?** - Before you can copy or paste content between the guest and host, :ref:`clipboard synchronization ` must be enabled. - **Did you install the Spice Guest Tools?** - The `SPICE Guest Tools driver `_ must be installed on the host OS to synchronize the clipboard. The download is labeled "spice-guest-tools". .. warning:: Do **NOT** install the QEMU Guest Tools driver. These are not the same. - **Is it installed 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.
