Could you try to reinstall package containing missed /usr/lib/i386-linux-gnu/egl/egl_gallium.so with
sudo apt-get install --reinstall libegl1-mesa-drivers ? Did you try to install scilab 5.3.3 from ubuntu repositories (sudo apt-get install scilab)? Does it work? Manual unpacking 5.5.1 to /usr/local may cause missed system dependencies. On my ubuntu I have many scilab versions - 5.3.3 from repository and newer versions (unpacked to ~/Software with custom launchers on desktop). 29 мая 2015 г. 4:28 пользователь "Tim Wescott" <[email protected]> написал: > 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. > > On Thu, 2015-05-28 at 23:58 +0300, Nikolay Strelkov wrote: > > I forgot to mention - I have 14.04 HWE > > ( https://wiki.ubuntu.com/Kernel/LTSEnablementStack#Desktop-1 ) on my > > Ubuntu 12.04.5 LTS. > > > > > > 28 мая 2015 г. 22:55 пользователь "Nikolay Strelkov" > > <[email protected]> написал: > > Dear Tim! > > > > > > I did some tests. > > > > Ubuntu 14.04.2 LTS i386: > > > > $ glxinfo | grep -i vendor > > server glx vendor string: SGI > > client glx vendor string: Mesa Project and SGI > > OpenGL vendor string: X.Org > > > > $ lsmod | grep drm > > drm_kms_helper 55071 1 radeon > > drm 303102 5 ttm,drm_kms_helper,radeon > > > > Your command works normally > > scf(0); clf; plot2d(sin((0:0.01:1) * 4 * %pi)) > > > > > > > > Ubuntu 12.04.5 LTS i386: > > $ glxinfo | grep -i vendor > > server glx vendor string: SGI > > client glx vendor string: Mesa Project and SGI > > OpenGL vendor string: VMware, Inc. > > > > $ lsmod | grep drm > > drm_kms_helper 49282 1 radeon > > drm 249595 3 radeon,ttm,drm_kms_helper > > > > > > > > Your command works normally > > scf(0); clf; plot2d(sin((0:0.01:1) * 4 * %pi)) > > > > > > > > So I have no problems with A4-4000 APU. > > > > What exact laptop model do have? > > I understood about AMD A10.
