# Tails Troubleshooting Guide #
|
||
|
|
|
||
|
|
## Black screen during startup
|
||
|
|
|
||
|
|
This was reported with earlier versions of Tails -- the problem should now be fixed.
|
||
|
|
If you do encounter a black screen during Tails startup, you can try to constrain display settings by appending vga codes to the Tails boot parameters.
|
||
|
|
If you do not know the codes, append `vga=999`, and a helpful prompt will appear.
|
||
|
|
|
||
|
|
Note: Tails 2.3 does not appear to honour the vga code.
|
||
|
|
|
||
|
|
## Window extends beyond the bottom of the screen
|
||
|
|
|
||
|
|
This problem seems to arise because Tails sizes to the height of the screen, but there is a title bar at the top of the window.
|
||
|
|
Either remove the title bar altogether, or move the window upwards using ALT+drag.
|
||
|
|
|
||
|
|
## Persistent tools do not work
|
||
|
|
The persistence tools, such as persistent volume, may not work because Tails has not been launched from USB.
|
||
|
|
The HVM disk(s) can be configured and mounted from within Tails to provide persistent storage.
|
||
|
|
If you want to use an existing USB persistent volume:
|
||
|
|
1. Interrupt the Tails vm boot process with arrow-up when the grub boot menu appears.
|
||
|
|
2. In dom0 attach the USB drive containing the persistent volume to the Tails VM.
|
||
|
|
3. Continue booting Tails. Tails-greeter will detect the encrypted partition on the attached USB.
|
||
|
|
4. Unlock the persistent volume in Tails-greeter and use it as normal.
|
||
|
|
|
||
|
|
## Tails qube doesn't shut down cleanly
|
||
|
|
If the Tails qube will not shut down cleanly, you can kill it from the GUI Manager or enter ```qvm-kill Tails``` in the console.
