Re: After update only opengl 1.4 instead of 2.0



Hello Hans,

i945 only supports OpenGL-1.4, it lacks a few hardware features to
reach 2.0: https://www.phoronix.com/scan.php?page=news_item&px=Mesa-i915-OpenGL-2-Drop

advertising it as 2.0 capable caused many issues, so mesa developers
decided to revert back to 1.4


best regards, Clemens
