Hi Ben, Karl, I'm very happy Karl could help diagnose this. (In reply to comment #30) > Give this a try: > http://cgit.freedesktop.org/~darktama/nouveau/commit/ > ?id=31080d6499d64e0578ef55f7473ed83b7bfd72af A janitorial mishap gave me an opportunity to (finally!) update the affected machine. It is now running v3.16-rc6, which includes commit 7fac4933 (matching your patch above). The remaining issues mentioned in comment #8 appear to be fixed in my configuration, too. Thanks! I think this ticket can be closed. Cheers, -D
