That is a storage driver failure. Boot from a live USB, run fsck /dev/sda1 , then reinstall the lvm2 and mdadm drivers.
| Problem | Solution | |----------------------------------|----------| | “Blue screen” after graphics driver | Boot safe mode → uninstall driver → use older Intel driver (v14.41.0) | | WiFi shows but won't connect | Check WPA2 compatibility – set router to WPA1 or mixed mode. Update WiFi driver. | | Audio plays but no sound from speakers | Check internal speaker connection (hardware) or install Realtek HD Audio Manager → toggle jack detection. | | Touchpad moves but no tap-click | Install Synaptics driver → enable tapping in Mouse Properties → Device Settings. | | Brightness keys don't work | Install ACPI driver from Canaima OEM pack or use brightness tool in Linux. | | Webcam not detected | Check USB device ID – often requires uvcvideo driver. In Windows, try Lenovo webcam driver (for Classmate). | drivers canaima letras azules
