anTraX with MATLAB 2019a freezes on Ubuntu 20.04 unless ran remotely #5
Comments
Thats weird. Can you load matlab itself from the same terminal? |
Yes, it loads normally |
Can you try launching the app from the matlab prompt?
|
The GUI loads from the MATLAB prompt, but does not find the session: I then realized I've seen this before in #4. Here I thought this issue was fixed because I tried running antrax from home with X forwarding, which worked then and works now for some bizarre reason. |
Let me get it straight:
Is that correct? |
I just found the problem... Since it would load properly through GeForce GTX 550 Ti + nvidia-driver-390 GeForce GTX 550 Ti + generic driver (all nvidia software purged) On-board graphics + generic driver Sorry I bothered you with this all along, the problem was on my side. Thank you again for all your help! |
I decided to test the above and installed anTraX on another computer with newer hardware (GeForce GTX 1650, nvidia-driver-430), but older software (Ubuntu 16.04). It loads fine with MATLAB R2019a full installation, but unlike what was discussed in #4 works with Do you happen to have an idea why an older GPU/driver is enough for MCR, but not for the full MATLAB installation? I am quite curious now. |
Sorry, no... this is probably a question for for matlab support, but unless it will come up again I'll probably let it be for now. Hopefully at some point in the future I will convert the code to be pure python. |
I am not sure if it is worth the effort. I think many of the weird problems I was dealing with were specific to my computers, rewriting the matlab code might just create a different set of problems. And here's a dramatic turn: if I I didn't have any such problems with MCR, it seems to load on all computer both locally and remotely. |
Just a quick update on this issue: I swapped GeForce GTX 550 Ti with GeForce GTX 1050 Ti and the problem I described here in the first post persisted with nvidia-driver-390. However, when I upgraded to nvidia-driver-460, the problem went away. Looks like the old nvidia-driver-390 was causing the weird issues in this case, GeForce GTX 550 Ti is not compatible with newer drivers. |
I have a very strange issue on my Ubuntu 20.04 computer: anTraX does not load GUI's unless I run it remotely (from another computer with
ssh -X
). I thought this might be a graphics problem, so I purged all nvidia software from the computer. That didn't help.Here is how it looks locally:
And remotely:
The content for the
matlab-antrax.sh
file (the first two lines are unnecessary, it loads without them through ssh as well):The GUIs (at least most of them) load fine with MCR, so this issue is not critical for me. I thought I should document this peculiarity here in case somebody else runs into this weird problem.
