Hi Axel,

Thanks for your reply!

I do have .vmdrc file under my home directory, but it already contains "menu main on" and "menu graphics on". Previously the main window and the graphic window would pop out automatically, but not any more now.

I just deleted the ~/.vmdrc file, and typed vmd. Again, only the OpenGL Display window appeared, and the text message got stuck there after showing:
Info) /usr/local/lib/vmd/plugins/LINUXAMD64/molfile

Subject: Re: vmd-l: unable to open VMD as normal

What you describe about your system suggests that it is not completely repaired.
Only a local person can help you with that.

The situation of having the OpenGL window but not the main VMD window can happen, when you have a .vmdrc file in your home directory but it does not include the command "menu main on" or there is an error when processing the file *before* it reaches the "menu main on" command.

Again, this is something local and usually self-inflicted.

Dear all,

Previously I had been running VMD smoothly on my Linux desktop (CentOS7) before the mother board and the power supply of the computer were replaced with the exact same models as the old ones.

After replacing the mother board and the power supply, my Linux desktop have several weird behaviors including failure of starting VMD:
(1) It cannot be rebooted to the normal login interface unless I choose the 2nd Linux core at the beginning process.
(2) It cannot find the inserted data hard drives. I have to unplug the data hard drives, then start the computer, then manually insert the hard drives one at each time and type commands to mount the hard drives one by one.
(3) When I type 'vmd', only the VMD OpenGL Display window is popped out, but the "main" window never appears. It seems that VMD is hanging there and waiting for something forever. The text messages on the terminal is as follows:

[xibing_at_qin ~]$ which vmd
/usr/local/bin/vmd

Can anyone help me figure out the reason behind? We can schedule a Zoom meeting so that you may access to my Linux desktop remotely.

Thanks!
