System Information
Ubuntu 15.04 Mate 1.8.2 64 bit
Nvidia GeForce GT 320M

Blender Version
Broken: official 2.77 and 2.77a
Worked: 2.76b

Short description of error
Under Ubuntu 15.04 Mate, by opening the attached file with the 2.77 and 277a official versions, Blender totally freezes not only itself but also the whole OS; only possible option is to turn the laptop off by the manual button and restart (even CTRL+ALT+CANC doesn't do anything).

By testing a bit, I found that the problem is in the (quite big) Olympus Mons mesh inside the file: I just deleted everything else and kept only that mesh (as in the attached file) and the freezes still occurs. Also, by opening the file in 2.76b (that instead works fine), hiding the mesh on a hidden layer and saving, gives the following: Blender opens the file without problems, but again everything freezes as I try to show the layer with the mesh.

I tried the same also with last official versions under WINDOWS 7, that instead work without problems.

Exact steps for others to reproduce the error
Just open under Ubuntu 15.04 Mate the attached file with the last 2.77 or 2.77a official builds.

Looks like attaching the blend file doesn't work, I cant see it anywhere. Just let me know if I need to send it to you by other means (it's a compressed 42 Mb zip).

Yes, file is missing… You should be able to drag-and-drop it in the comment area (and wait until it’s uploaded), or else please use some other webservice (dropbox, gdrive, etc.).

Drag-and-dropping the file again:

blendercrash.zip

OK, seems it worked this time. :)

OK… file loads OK here (debian64 testing, on both integrated intel GPU and on the NVidia GTX 850m).

Now, 1M mesh is rather heavy, and GT320m is rather low-end GPU, and ubuntu 15.04 is rather old. So first bet would be, too old distro (i.e. GPU drivers), please try with a recent ubuntu (use a liveCD or so if you do not want to install it). Also, please do check you are using proprietary nvidia's drivers, not nouveau free ones (those are not officially supported).

Ubuntu 15.04 is rather old, really? And yes, I have the right drivers.

Btw, as I already explained, I can open the file without any problem with Blender 276b, so obviously the problem started with something odd in 2.77 and 2.77a.

Hi, I can open file with Blender 2.77a on:

Opensuse Tumblweed x86_64
CPU Intel #4200 4 GB
GPU Intel GN 965
xf86-video-intel 2.99.917-6.1

This is really old laptop with crappy Intel GPU, must be something else.
Enrico, do you get any error messages when you start Blender from terminal?

Tested the file on AMD X3 455, R7 360.

Xubuntu 15.10, proprietary driver 15.201.1151
Blender Version : 2683dd8

Ubuntu 14.04 LTS, Mesa 10.3.2
Blender Version : d09a372

Arch Antergos, Mesa 11.1.2
Blender Version : d09a372

All opened the file fine. Ubuntu 14.04 2D performance in general with the old Mesa is bad compared to the new one for my card. But that is not Blender's fault :)

Wolfgang, as far as I understand no particular errors besides missing addons.
I attached a screengrab.

I added also the screengrab of 276b (that has no problems in opening the file):

The only difference I can see in the console is the "version 3 imported" line for 2.77a, I have no idea what it means.

Hi, you can start Blender from terminal with gdb blender > run
Gnudebugger should save your OS from freeze and you get may info what happen.
Type bt should give even more information.
Such errors are hard to catch when it only happen on your system as it seams.

Cheers, mib

Mib, I installed gdb and tried to run blender with the gdb blender > run command line: nothing happens, the cursor keep on flashing inside the console window and that's all.

Btw, if this freezing happens only to me under my system, probably there's no reason to keep this bug report still open. :)

Maybe mistyping. :)
Type gdb blender
Type run
After freeze or crash.
Type bt

:) I got it now.

Started blender 2.77a with the gdb option and everything OK until I tried to load the blendercrash.blend file, then again instant freeze of everything and no way to type bt or read something in the terminal, sorry.

Several questions and suggestions:

See if the file crashes when using blender-softwaregl
See if the file crashes in 2.76 when enabling VBO option in User Preferences -> System
See if blender crashed when opening the file without loading UI

Hi Sergey. :)

OK:

2.77a, started using blender-softwaregl, opens the file without problems (but obviously with very low performances)
instead, contrary to what formerly happened, Blender 2.76b crashes with VBO enabled, but it doesn't freeze also the OS
last, both 2.77a and OS totally freezed as before even without loading the UI.

So this points to OpenGL driver issue. We cannot do much here really, just try to get newer drivers (again, those featured with Ubuntu15.04, even proprietary NVidia ones, are quite old now).
