Trouble launching mne_analyze

Dear MNE experts,

I used to run mne_analyze in the past.
However, today when I tried to launch it
by "mne_analyze --subject XXX", I could
not see its GUI and got the following error
message instead:

"Using a 4096-point FFT in filtering of raw data with 2048-sample tapers.
Desired visual not found."

I'm using VNC connections but mne_browse_raw
and tkmedit are just fine without any X-window/OpenGL issues.
The version of mne_analyze is 2.51 and the SUBJECTS_DIR variable
is correctly set to the MRI directory under CentOS 5.3/tcsh.

Any experience or idea on this?

Thanks!
Tren

Dear all,

Using vncserver.glx instead of vncserver solves the problem.

Best,
