Running the 'unity' desktop environment is not fully supported by your graphics hardware. You will maybe end up in a very slow environment after the upgrade. Our advice is to keep the LTS version for now. For more information see https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you still want to continue with the upgrade?
Zure grafikoen hardwareak ez du guztiz sostengatzen 'unity' mahaigain-ingurunea. Baliteke bertsio-berritzearen ondoren ingurune oso motela izatea. Oraingoz LTS bertsioa mantentzea gomendatzen dizugu. Informazio gehiagorako ikusi https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D. Hala ere, bertsio-berritzearekin aurrera egin nahi duzu?
