Hey, <br>i kept on searching tweaks for my ATI driver on ubuntu to be able to use Pd in a efficient way (&#39;cause the downgrade didn&#39;t sound so cool since i just installed 9.04).<br><br>I finally found this links, and the tweaks explained in there are really helping. Motionblur works nicely and i can use [gemframebuffer] and glsl-related. CPU is still high&amp;higher but i will look into it.<br>
So this stuff could help someone else too in the future:<br><br><a href="https://help.ubuntu.com/community/RadeonDriver">https://help.ubuntu.com/community/RadeonDriver</a><br><br><a href="http://www.thinkwiki.org/wiki/Additional_options_for_the_radeon_driver">http://www.thinkwiki.org/wiki/Additional_options_for_the_radeon_driver</a><br>
<br>also tons of other options are available via terminal --&gt; man radeon<br>(but this is not a big discovery)<br><br>cheers<br><br><br>M<br><br><br><div class="gmail_quote">2009/8/14 Marco Donnarumma <span dir="ltr">&lt;<a href="mailto:devel@thesaddj.com">devel@thesaddj.com</a>&gt;</span><br>
<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">mmm.. i found out the truth.<br>i write this just for information (probably most of you already know it but it can be useful to post it anyway).<br>
<br>catalyst 9.3 and earlier drivers don&#39;t support x 1.6 and catalyst 9.4 doesn&#39;t support a bunch of older radeon cards (as mine).<br>
This means the only option one has is to downgrade to ubuntu 8.10.<br><br>M<br><br><br><br><div class="gmail_quote">2009/8/14 Marco Donnarumma <span dir="ltr">&lt;<a href="mailto:devel@thesaddj.com" target="_blank">devel@thesaddj.com</a>&gt;</span><div class="im">
