<div dir="ltr">Thanks for concrete answer. I rebuilt my xf86-video-intel driver with glamor, SNA and UXA support enabled but unfortunately it did not help. My "815 E" chipset still works slow. I think it is because glamor, SNA and UXA does not support my chipset, right ? If so, is it going to be supported in the future or this chipset is just to old. thanks for an answer </div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Apr 5, 2013 at 5:20 PM, Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk" target="_blank">chris@chris-wilson.co.uk</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im">On Fri, Apr 05, 2013 at 05:07:07PM +0200, j j wrote: > I performed an update very carefully.
