I'm running Lubuntu 14.04. I installed fglrx, and the behavior got worse. Before, Scilab would run for a while. Now, it gets to the first graphics issue and bombs.
I'm going to try uninstalling fglrx and see what happens. I'm going to be getting desperate here soon -- this is my work machine, I'm in the middle of a project for a customer, and I'm stuck here. (Disabling on-board video and buying a graphics card is an option). I start scilab from the command line and get: libEGL warning: DRI2: failed to authenticate Then at the Scilab prompt I type scf(0); clf; plot2d(sin((0:0.01:1) * 4 * %pi)) I get a nice graph. Then I close the graph window, and Scilab tanks, with the following message: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0xb6ddc289, pid=4421, tid=543931200 # # JRE version: 6.0_41-b02 # Java VM: Java HotSpot(TM) Server VM (20.14-b01 mixed mode linux-x86 ) # Problematic frame: # C [libscilab-cli.so.0+0x185289] short+0x9f # # An error report file with more information is saved as: # /home/tim/Documents/Customers/Pacesetter/Technical/Software/particle/ScilabCode/hs_err_pid4421.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # The crash happened outside the Java Virtual Machine in native code. # See problematic frame for where to report the bug. # [error occurred during error reporting (null), id 0xb] Aborted (core dumped) On Wed, 2015-05-27 at 08:15 +0300, Nikolay Strelkov wrote: > Dear Tim! > > For me it seems that you need to use proprietary AMD drivers - fglrx. > Open drivers are buggy and show low-performance. > > If you want to use open driver on Ubuntu 12.04 LTS (precise) you > should upgrade its HWE to 14.04 LTS (trusty). > > With best regards, > Nikolay. > > > 27 мая 2015 г. 3:22 пользователь "Tim Wescott" <t...@wescottdesign.com> > написал: > Running a Scilab algorithm that puts up a lot of graphs, > Scilab crashes > with the report below.
