Harald, though kwin did run (as I reported before), the patch was somehow lost, so I had distorted popup shadows again... I tried it again and again, the same result. This was with the command sequence: apt-get source kde-workspace apt-get build-dep kde-workspace cd kde-workspace-* <apply patch> fakeroot make -f debian/rules configure cd obj-i686-linux-gnu/ make kwin cd kwin sudo make install how is it that the patch was lost? May be I applied the patch not at the right moment? However, I succeeded the second way – built kwin the regular way (described in my first email) and then symlinked the libkephal.so.4 to libkephal.so.4.7.0.abi1 Donatas <div class="gmail_quote">2012/2/13 Harald Sitter <<a href="mailto:apachelogger@ubuntu.com">apachelogger@ubuntu.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div class="im">On Mon, Feb 13, 2012 at 4:36 AM, pansz <<a href="mailto:pan.shizhu@gmail.com">pan.shizhu@gmail.com</a>> wrote: > On Sat, Feb 11, 2012 at 3:49 AM, Donatas G. <<a href="mailto:dgvirtual@akl.lt">dgvirtual@akl.lt</a>> wrote: >> apt-get source kde-workspace >> apt-get build-dep kde-workspace >> cd kde-workspace >> <apply patch> > > probabaly the more official way to compile "apt-get source" package is > : dpkg-buildpackage -b -uc > you need to have installed fakeroot. > > After compile you could just find the kwin executable and cp kwin to /usr/bin. </div>Very true. Except that will take 6 hours and is what Donatas wanted to avoid :) <div class="HOEnZb"><div class="h5"> -- kubuntu-devel mailing list <a href="mailto:kubuntu-devel@lists.ubuntu.com">kubuntu-devel@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/kubuntu-devel" target="_blank">https://lists.ubuntu.com/mailman/listinfo/kubuntu-devel</a> </div></div></blockquote></div>
