That's obiouvsly an error that nVidia should fix, but in the latest months nothing has changed!); then Vladimir posted in this list asking the use-copy feature for using compiz in fglrx drivers too, that's why I passed the latest night in porting the code to Compiz and... All works well!

However I'm not so intrested on what ATi offers in their proprietary drivers, since I do really prefer using the free ones... My wish so is that AMD whould release specs instead of binaries... <blockquote cite="mid1184004872.19945.3.camel@localhost.localdomain" type="cite"> <pre wrap="">If this is really needed I think the copy mode patches implemented as a plugin by onestone are better because they avoid cluttering the core with workarounds. </pre> </blockquote> Of course... I think the same. I didn't know that code until Maniac linked me it... It's really better from a code and implementation point of view, and of course that is the code that should be merged, but from my point of view it's hard to maintain since it changes really many parts of the code... So that should be the choice, but only if merged upstream! <blockquote cite="mid1184004872.19945.3.camel@localhost.localdomain" type="cite"> <blockquote type="cite"> <pre wrap="">As in beryl now you'll have an "--use-copy" flag that you could use to load compiz also if you don't have the texture-from-pixmaps support I've tested this with nvidia and radeon (free drivers) and compiz works correctly I've not added an ABIVERSION change in patch, not to update the patch on each compiz change, however as you'd know it's absolutely needed that you recompile every plugin after applying this patch. </pre> </blockquote> <pre wrap="">Actually this doesn't exactly change the ABI so plugins would work without recompiling AFAIK. </pre> </blockquote> Eh, that is what I thought, however without recompiling them all I got a segmentation fault, that's why I said that maybe should be changed... <pre class="moz-signature" cols="72">-- Treviño's Blog - Life and Linux <a class="moz-txt-link-freetext" href="http://3v1n0.tuxfamily.org/blog/">http://3v1n0.tuxfamily.org/blog/</a> </pre> </body> </html>
