I'm thinking of upgrading my Ubuntu Studio PC, and to avoid all the problems I had with the current one (lock or slow mouse on a setup based on an MSI 7312 motherboard), can you recommend a 'working' setup (specially the motherboard, due to all the known ACPI problems with the RT kernels)? I intend to "upgrade" my current setup (MSI board) with an ASUS motherboard with a Athlon II CPU. Some of the motherboards I've identified are:
ASUS M2N68-AM PLUS - NVIDIA nForce 630a + Geforce 7025 GPU Asus M4A785D-M Pro - AMD 785G chipset ASUS M4A785TD-M EVO - AMD 785G chipset Any of you have any of these boards working with Ubuntu Studio (with RT kernel)? I also had a previous PC with the AMD780G chipset and had similar problems with the RT kernel, that was the reason to change to the one I have now (with the MSI7312 motherboard, using the K9MM-V chipset), but still have almost the same issues - freezing after boot, mouse getting very slow after some seconds / minutes of use, etc. Or can you suggest any other known working setup? Thanks!
