# Display Issue on Ubuntu 24.04 with kernel 6.8
## Problem Description
On Ubuntu 24.04 LTS with kernel 6.8 (specifically 6.8.0-52.53~22.04.1), a major display issue occurs when booting the system.
### Symptoms
- Black screen at startup
- No brightness control
- Need to use recovery mode to access the system
## Hardware Configuration
- Lenovo Yoga Pro 7 14ASP9
- Processor: AMD Ryzen AI 9 365
- Integrated Graphics Card: AMD Radeon 880M
## Working Solution
### 1. Upgrade to kernel 6.12 LTS
```bash
sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline
sudo mainline install-latest
```
After installation, restart the system.

### 2. Switch from Wayland to X11 (to resolve lags)
Edit the GDM configuration file:
```bash
sudo nano /etc/gdm3/custom.conf
```
Uncomment (remove the `#`) the following line to disable Wayland:
```
WaylandEnable=false
```
Restart the system or the GDM service:
```bash
sudo systemctl restart gdm3
```
