Ubuntu 12.04 x86_64 kernel 3.2.0-35-generic Mathematica 9 linux version (x86_64) crashes with errors:

X Error of failed request: BadGC (invalid GC parameter)
Major opcode of failed request: 59 (X_SetClipRectangles)
Resource id in failed request: 0x0
Serial number of failed request: 2266
Current serial number in output stream: 2268

X Error of failed request: BadGC (invalid GC parameter)
Major opcode of failed request: 59 (X_SetClipRectangles)
Resource id in failed request: 0x0
Serial number of failed request: 2267
Current serial number in output stream: 2268

...

The above errors occur when I run command mathematica as a general user. It crashes before GUI is started. However, if I run it as root sudo mathematica, all work well.

Can someone fix this problem?

How good are you with the command-line? This answer suggests, that it is a problem with the wrong Qt-libraries. You could use ldd to find out which libraries are used but it's a bit of work. – halirutan Jan 2 at 4:10
Antoher thing: Which desktop-environment are you using? I use the classic gnome (otherwise I have the same system as you) and everything works fine. Have you tried to select a different one? You can do this at the login-screen. – halirutan Jan 2 at 4:13
I use KDE desktop. – goodluck Jan 2 at 4:57
And can you debug what Qt libraries are use? If not, you can come to chat and I help you. – halirutan Jan 2 at 5:31

Thank halirutan very much! It's really the problem of a setting for QT. Mathematica9 crashes when "systemsettings -> Qt Graphics System -> Raster" is selected. This changes the file ~/.kde/env/qt-graphicssystem.sh and hence the QT_GRAPHICSSYSTEM envirenment variable.

QT_GRAPHICSSYSTEM=native  mathematica   # work
QT_GRAPHICSSYSTEM=raster  mathematica   # crash
QT_GRAPHICSSYSTEM=opengl  mathematica   # work

Here is a detailed instruction on how to install Mathematica under Linux (with pictures, in Russian) install mathematica 9

A link to a Russian language web site is not particularly useful to the general public, is it? – Sjoerd C. de Vries Apr 9 at 21:53
I don't think these instructions are terribly useful since pretty much anyone will be able to work this out for themselves, and if not information is available on the WRI website anyway. Plus, what appears to be a keygen is visible in one of the screenshots... c'mon... – Oleksandr R. Apr 23 at 11:45
