[h1]Test result:[/h1]
[p]The Live installation image of Trisquel 6.0 would not login to its desktop environment. Almost everything worked as expected when using netinstall instead (it downloads the latest kernel and driver). Compiz and OPENGL does not work with mesa 9.2 and 9.3 by the time of August 2013. USB Audio DAC dropout from time to time but always with Chromium scrollbar movement (not observed with Intel HD Graphic and AMD + llvmpipe driver).[/p]

[h1]Audio dropouts[/h1]
[p]Audio dropouts cause crackling noise from time to time, especially with Chromium scrollbar movement. Such dropouts do not occur with Intel HD Graphic and AMD + vesa driver. The dropouts of VLC can be alleviated by passing the audio via JACK. System-wide dropouts can be alleviated by changing Pulseaudio settings, stated below.[/p]
[code]
$ sudo gedit /etc/pulse/daemon.conf
[/code]
[p]Change the following settings as stated:[/p]
[code]
lock-memory = yes
realtime-scheduling = yes
realtime-priority = 10
[/code]
[p]Do not turn on High priority in /etc/pulse/daemon.conf . Do not turn on JACK unless using VLC.[/p]
