I've built a HTPC running Linux (Ubuntu 12.04) w/ AMD Liano processor and a Fusion motherboard with HDMI. Initially I was using AMD processor and Catalyst driver output to HDMI.
Then I realized that video decoding acceleration is poor with this combination. I've installed vaapi acceleration packages but XBMC refused to work with it. Not to mention even flash acceleration is not working as it requires vdpau.
So I brought a Nvidia GT 520 card for this. Lucky the card is quiet cheap
Once I installed the card with Nvidia proprietary driver, everything seems to now well with output going to the HDMI in Nvidia card. Sound works great, video acceleration works as well with vdpau as I can see Chrome Flash youtube is now consuming very few processing power. Of course I've the blue tint problem with the flash but I managed to fix it with the /etc/adobe/mms.cfg thing.
However a problem happens.
Whenever I try to logout (either my Unity session or a delicated XBMC session), the system freeze with some console message (I can't recall exactly "SYSV service stop......" or "using libgcrypt-1.5 ...." and I cannot get back to the login screen (I'm using ubuntu so it should be lightdm).
I tried to ping the machine and SSH to it. Ping responses with either problem with connection or reply with a very long latency. SSH doesn't work (I think probably due to long network latency). Seems like the machine is still on but with a very high CPU utilization.
Keyboard / mouse is not responding (alt-ctrl-f1 doesn't work) and I've to hard reset the machine.
Anyone have similar issue and any fix? Now I've reverted back to AMD (and open source radeon driver which seems to work pretty well). Really hope that I can get some video decoding acceleration.
