We have detected some issues with colored boxes, flickering of some areas of the screen, and even a loss brightness to 0% (similar to a shutdown), which is due to a conflict with the free AMD graphics driver included in the Linux kernel, in versions lower than 6.11. Here you will find a step-by-step tutorial to apply a solution..
Step 1: Edit the GRUB Configuration
Open the GRUB configuration file. Open a terminal:
1. Type the following command to edit the GRUB configuration file using a text editor (you can use `nano` or your preferred editor):
| sudo nano /etc/default/grub |
2. Modify the kernel command line. Locate the line that starts with: GRUB_CMDLINE_LINUX_DEFAULT
3. Add `amdgpu.dcdebugmask=0x10` at the end of the parameters within the quotes. For example:
4. Save the changes:
In `nano`, press `Ctrl + O`, then `Enter` to save.
Exit the editor by pressing `Ctrl + X`.
Step 2: Update GRUB
In the same terminal, run the following command to update GRUB with the changes made:
| sudo update-grub |
Step 3: Restart the System
Restart your computer to apply the changes:
| sudo reboot |
Step 4: Verify the Solution
After rebooting, check if the screen flickering has stopped. Open a browser, move windows, or play a video to see if the issue persists.
If you continue to experience flickering, graphical glitches, random restarts or similar problems, I recommend reviewing our other tutorials before contacting technical support.
