Hi Mohammad, This error typically indicates that the PyMOL installation interferes with a different Qt installation on your system. I though we have this under control, our launcher script unsets all (known) interfering environment variables.
Can you check which Qt environment variables are set on your system? Type this into a terminal: env | grep QT Our libraries should also be unaffected by LD_LIBRARY_PATH, but just in case, can you also check: env | grep LD For your information, libqxcb should be picked up from pymol/plugins/platforms/libqxcb.so, not from /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so Cheers, Thomas > On Jul 4, 2018, at 9:39 PM, Mohammad T Mazhab Jafari <mazha...@gmail.com> > wrote: > > Hello, > > I am trying to run pymol on my linux computer (Ubuntu 17.10). > > I downloaded PyMOL-2.1.1_0-Linux-x86_64.tar.bz2 > > then unpacked with > > tar -jxf PyMOL-2.1.1_0-Linux-x86_64.tar.bz2 > > When I try to execute pymol from the pymol folder, I get the following > message. > > This application failed to start because it could not find or load the Qt > platform plugin "xcb" > in "". > Available platform plugins are: eglfs, minimal, minimalegl, offscreen, xcb. > Reinstalling the application may fix this problem. > Abort (core dumped) > > I have libqxcb, > > locate libqxcb > /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/libqxcb.so > /usr/lib/x86_64-linux-gnu/qt5/plugins/xcbglintegrations/libqxcb-egl-integration.so > /usr/lib/x86_64-linux-gnu/qt5/plugins/xcbglintegrations/libqxcb-glx-integration.so > > > Any idea how to solve this issue? > > Thanks. > M. -- Thomas Holder PyMOL Principal Developer Schrödinger, Inc. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ PyMOL-users mailing list (PyMOL-users@lists.sourceforge.net) Info Page: https://lists.sourceforge.net/lists/listinfo/pymol-users Archives: http://www.mail-archive.com/pymol-users@lists.sourceforge.net
