Probably not very useful. Hm, is there anything in dmesg/Xorg.log about this freeze when you switch to pipe C? Can you try to connect gbd to X and grab a backtrace to figure out where it is stuck (note: don't vt-switch when gdb is connected to X, it sends a signal to X, which gdb intercepts and then stops X, resulting in a hung vt-switch ...)? -Daniel -- Daniel Vetter Mail: daniel at ffwll.ch Mobile: +41 (0)79 365 57 48
