Hi! I've discovered that I can't run OpenGl contexts while using Plasma. Example: install qtbase5-examples and run: /usr/lib/<arch triplet>/qt5/examples/widgets/graphicsview/chip/chip The chip example starts perfectly but after clicking on "OpenGL" on any of the views either a black screen or a static image of the chips is showed. Changing any parameter won't affect it. I tried to debug this and I: - Closed plasma+sddm and then run startx xterm. Ran the example from there and OpenGL works perfectly → X issue possibly discarded. - Tried the three available renderization engines for Plasma: OpenGL 3.1, OpenGL 2.0 and XRender, restarting the session after setting the engine and then running the chip example. No OpenGL. - Checked Xorg.0.log, nothing. - Checked .xession-errors, nothing. - Checked the above two files with tail -F and started the app, changed OpenGL status... nothing. I'm using an Intel video card here, but I suspect the problem is somewhere else. Does anyon has any other idea on what should I check? Thanks in advance, Lisandro. -- Un viejo proverbio de El.Machi dice que la memoria es como las papas fritas... ¡nunca sobran!
