[h1]Test result:[/h1]
[p]The Live installation image of following test result was collected in August 2013. Trisquel 6.0 LiveCD would not login to its live desktop environment. Almost everything worked as expected when using Use netinstall instead (it downloads in order to install the latest system. Even with the up-to-date kernel and driver). drivers from the official repository, the login screen would not appear after the installation. Just a black screen. It seems the system would not switch to VESA driver automatically. Use another display card (Intel/AMD) to install a newer kernel (3.10.5-gnu) and nouveau driver (1.0.9) in order to make it work. Compiz and OPENGL does not work with mesa 9.2 9.2-devel and 9.3 by 9.3-devel, fallback to metacity window manager to display 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] title bar.[/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:[/p]
[code]
; lock-memory = yes
; realtime-scheduling = yes
; realtime-priority = 5
[/code]
[p]into:[/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]
