But my first concern ATM is to get this system in a usable state - that's what the customer pays me for. On of the many things I tried before even posting was to use the nv driver. Modified the xorg.conf, but for some reason, the system goes on using nouveau regardless. ** Is it still possible to use nv on today's Arch ? ** I've used nv for years without any problem. The reason to prefer it over nvidia was not ideological - nvidia has latency problems as well, and I never needed 3D acceleration. Looking at the xrun statistics in function of audio period size, it looks like current nouveau is blocking audio (either by dis- abling interrupts, or by locking a shared HW resource) for about 3-4 ms. *No* driver today should ever do that - it's really late 1990's performance. > The work to provide good, detailed, and useful bug reports is in > user's hands, not developers'. > When the users don't do their homework, regressions remain. Agreed. Ciao, -- FA O tu, che porte, correndo si ? E guerra e morte !
