# Software & System FAQ

### My computer is slow/laggy after updating

Switch or enable a GPU hacks in
[reconfigure](../../desktop#system-reconfiguration-tl-sys-configure)

### Login as admin

```bash
su admin
# pass : `empowerwatoto

# if you want clean env vars
su - admin
su -l admin
```

### Component not installed

```bash
mkdir /srv/component_name

### How do I switch between the graphical desktop and a TTY?

You can switch to {{< term "Admin Mode (TTY2)" >}} if the graphical desktop is frozen or for admin tasks like updating.

- **To switch to TTY2:**
    - On most computers: <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F2</kbd>
    - On Apple computers: <kbd>CMD</kbd> + <kbd>Option</kbd> + <kbd>F2</kbd>
    - In rare cases: <kbd>FN</kbd> + <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F2</kbd>
    - As admin: `sudo chvt 2`

> [!TIP]
> If the key combinations don't work, try connecting an external USB keyboard.
> Sometimes, a built-in keyboard might be broken or unresponsive.

- **To switch back to the graphical desktop (TTY1):**
    - Exit fbterm with `exit` then use <kbd>Ctrl</kbd> + <kbd>Alt</kbd> + <kbd>F1</kbd>.
    - You can also use <kbd>Super</kbd> + <kbd>Alt</kbd> + <kbd>←</kbd>.
    - As admin: `sudo chvt 1`.

### My computer hostname is mismatched with the tag

Use [reconfigure](../../desktop#system-reconfiguration-tl-sys-configure)

### Fix storage issues ("Disk Full" Error)

Use [tl-comp-manage](../../desktop#components-management-tl-comp-manage) to remove old {{< term "Btrfs Snapshots" >}} and free up space.
