Die Schieberegler im Entwickeln-Modul lassen sich nur mit gedrückter ALT-Taste verschieben. Was mache ich falsch?

Do you mean moving with the mouse or moving with the up- and down-arrow keys?

with the mouse, with arrow-keys is working well

In a first step try is to reset the preferences to the default settings.

• Reset Procedure:
• Close Lightroom.
• Windows: Hold down [Alt]+[Shift] while restarting Lightroom.
  Mac: Hold down [Opt]+[Shift] while restarting Lightroom.
• Overwrite the Preferences when prompted by the dialog.
• Close Lightroom.
• Restart Lightroom.

It's recommended to backup your preferences before you reset the preferences to the default settings:
