Tried with the old sandy bridge again: [ 819.027] (II) Module intel: vendor="X.Org Foundation" [ 819.027] compiled for 1.20.5, module version = 2.99.917 ... [ 819.039] (--) intel(0): Integrated Graphics Chipset: Intel(R) HD Graphics 30 00 [ 819.039] (--) intel(0): CPU: x86-64, sse2, sse3, ssse3, sse4.1, sse4.2, avx; using a maximum of 2 threads ... [ 819.040] (II) intel(0): SNA initialized with Sandybridge (gen6, gt2) backend Before all the updates, e.g. last year, it worked with SNA and no TearFree. Now, when displaying images, e.g., with GraphicsMagick, I see horizontal line segments which eventually get filled in. Otherwise, e.g., all the xterms in the world, work fine, as do e.g. 2 copies of glmark2, with a score of 182. Work arounds include (all with TearFree off): - switch to UXA (glmark2 score of 50) - switch to modesetting driver (glmark2 score of 50) On another front, I cannot boot a computer with nouveau and a NVidia GeForce GTX 680 (GK104). At the point where the console normally changes resolution, the screen goes black and everything stops. (No panic AFAICT) Cheers, Patrick
