+# GUI Troubleshooting
+
+If you can start your VM, but can't launch any applications, then you need to fix the issues from the `VM console`, accessible from xen through:
+
+~~~
+qvm-start <VMname> # Make sure the VM is started
+sudo xl console <VMname>
+~~~
+
+## Tips
+
+### Disable auditd messages
+
+To disable auditd messages, you need to edit your VM kernel parameters:
+
+~~~
+previous_kernel_parameters=$(qvm-prefs --get <VMname> kernelopts) # Get current kernel parameters
+qvm-prefs --set <VMname> kernelopts "<previous_kernel_parameters> audit=0"
+~~~
+
+Then, restart your VM.
+
+Once your troubleshooting is done, don't forget to remove this kernel parameters, it makes troubleshooting VMs not starting easier.
