The following error occurs when you install Comsol Multiphysics 10.04 on Ubuntu 4.2:

The program 'swt' has ed an X Window System error.
This probably reflects a bug in the program.
The error was 'baddrawable (invalid Pixmap or Window parameter )'.
(Details: serial 2135 error_code 9 request_code 136 minor_code 3)
(Note to programmers: normally, X errors are reported asynchronously;
That is, you will receive the error a while after causing it.
To debug your program, run it with the-sync command line
Option to change this behavior. You can then get a meaningful
Backtrace from your debugger if you break on the gdk_x_error () function .)

There is a way to add a line of graphics. rendering.2drend = swing in the. comsol/v42/comsol. prefs file. I find this method does not work for me. In fact, the cause of this error is that the video card driver is incorrect, or the driver is not properly installed. The Ubuntu graphics card driver may not work well, but it can be replaced by runningComsol-3 drend swThe command ignores the 3d display function to run comsol, so that comsol can run perfectly.
