# 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.
