Goldberg <dark_sylinc@yahoo.com.ar>"> Matias N. Goldberg</a> <pre>This could be caused by the Ubuntu's Unity Compositor (Compiz). You could try forcing VSync off in one of Compiz config/tweak tools. It could also be caused by the tear free parameter. To test that try: xrandr --output VIDEO --set TearFree off where "VIDEO" is the name of your monitor output; you can find out by just running "xrandr" and it will list all of your monitor outputs. For example mine reads: HDMI-A-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 510mm x 290mm 1920x1080 60.00*+ 50.00 59.94 1920x1080i 60.00 50.00 59.94 1680x1050 59.88 1400x1050 59.95 1600x900 60.00 1280x1024 60.02 1440x900 59.90 1280x800 59.91 1152x864 75.00 1280x720 60.00 50.00 59.94 1024x768 60.00 800x600 60.32 720x576 50.00 720x480 60.00 59.94 640x480 60.00 59.94 Thus I should write: xrandr --output HDMI-A-0 --set TearFree off</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
