I upgraded to the 14.04 HWE, and now I can't show a graph at all. I can change the problems that I get, but basically I start Scilab and get:
libEGL warning: Could not open driver /usr/lib/i386-linux-gnu/egl/egl_gallium.so (/usr/local/share/scilab-5.5.1/lib/thirdparty/libgcc_s.so.1: version `GCC_4.7.0' not found (required by /usr/lib/i386-linux-gnu/egl/egl_gallium.so)) libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/fglrx/dri:/usr/lib/i386-linux-gnu/dri:/usr/lib/dri) libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/fglrx/dri:/usr/lib/i386-linux-gnu/dri:/usr/lib/dri) libEGL warning: DRI2: failed to authenticate libEGL warning: DRI2: failed to open swrast (search paths /usr/lib/fglrx/dri:/usr/lib/i386-linux-gnu/dri:/usr/lib/dri) At this point I try to open a graph (plot2d(1:10)), the graph window opens, and Scilab freezes.
