AFAIK, llvmpipe is used by the Modesetting DDX, while Radeon DDX uses AMD CEDAR. Whether either could possibly use the other I have no idea, but since the Modesetting uses a very different technology, I suspect it's not possible. >> Info:...Shell: Bash v: 5.1.4 running in: konsole inxi: 3.3.00 >> # dmesg | grep adeon ... >> [ 38.389555] radeon 0000:01:00.0: VRAM: 1024M 0x0000000000000000 - >> 0x000000003FFFFFFF (1024M used) >> [ 38.389561] radeon 0000:01:00.0: GTT: 1024M 0x0000000040000000 - >> 0x000000007FFFFFFF >> [ 38.389820] [drm] radeon: 1024M of VRAM memory ready >> [ 38.389824] [drm] radeon: 1024M of GTT memory ready. ... > similar but only 512M vram. I suppose the hang could be from CPU initializing VLC before the video actually starts running. Have you tried watching top as you start VLC? How powerful is your CPU? When I have trouble with VLC, I often find trouble absent using SMplayer. -- Evolution as taught in public schools, like religion, is based on faith, not on science. Team OS/2 ** Reg.
