Running Ubuntu MATE 15.10 with Compiz enabled. The X-server apparently crashes every time Stellarium is run. The crash is not immediate, I can pan and zoom the sky with no problems. The crash seems to occur as soon as I try to interact with the menus -- or if I close Stellarium. In this state, all visible GUI elements are frozen except for the mouse cursor.

The system is not completely dead -- I can still switch to a console with Ctrl-Alt-F1, and can still restart the X-server with Ctrl-Backspace.

There is no problem if Compiz is disabled. Also, I have run several other full-screen 3D games and apps with no similar problems. My machine has NVIDIA, but I believe it is using Intel (Broadwell) Graphics. This error post was helpful for me because it reminded me to try without Compiz.

Mistake in my prior post: I can restart the X-server with Ctrl-Alt-Backspace.

I too am getting the same issue. However, for me the crash doesn't happen until I try to resize the window - like exiting from full screen via F11 or even just exiting the application. In addition, just attempting to switch to a different workspace also causes X/Unity to hang!

On my system, CTRL+ALT+Backspace has never worked. However, I can CTRL+ALT+F1 and from there restart lightdm and all is well again!

I'm running Ubuntu 15.10:

I believe my problem to be solved!

After adding ppa:stellarium/stellarium-releases and then running apt-get dist-upgrade, I can re-size and move application to any workspace without issue.

Never mind, crashing has reared its ugly head again; I guess I got excited since on first launch it lasted for more than 10 minutes and figured the issue was resolved - :)!

[Ingo Haase (haase)]

Same here on a freshly installed Ubuntu 15.10 (i5, Intel HD 5500 graphics). CTRL+ALT+Backspace won't work.

[Alex Thompson (alexofdoom)]

Adding the Stellarium project to this bug. I'll try to add more details here to enable the develops to debug this issue, although I understand as I see nothing in any error logs.

I'm using the latest Stellarium from the release PPA on Ubuntu 15.10 x64 (0.14.2-1ubuntu1~ppa3~ubuntu15.10.1). The system is a Intel Core i3-3240 CPU and I'm using the integrated graphics (HD Graphics 2500 with i915 driver).

Similar to the other bug reporters, I get a full X hang. I can return to a terminal to kill X (using Ctrl+Alt+F1) and restore access to my system.

There are no error messages in the X.org log file, syslog or dmesg.

I have attached the stellarium log after launching stellarium with the -d option. I see no error messages in this either.

[Alexander Wolf (alexwolf)]

Alex, what exactly you are doing within Stellarium before X has been hanged?

[Alex Thompson (alexofdoom)]

Changing from fullscreen to windowed instantly hang everything, but it seems to hang without a trigger after 30-60 seconds.

[Alexander Wolf (alexwolf)]

Please run through CLI: mv ~/.stellarium ~/.stellarium.orig and check it again

[Alex Thompson (alexofdoom)]

Sorry for my very slow response.

I still see this issue after moving removing the config (#12) and switching to windowed mode (F11)

[shankao (shankao)]

@alexwolf: is there any other info that we can help to provide? Otherwise I'd change the status back to 'Confirmed' to give it some relevance.
This makes stellarium unusable on Ubuntu, and crashes the X server. That should not happen anyway. :(

[shankao (shankao)]

Confirmed as happening in Xenial too

[shankao (shankao)]

Changing package as per https://wiki.ubuntu.com/X/Triaging

[Alexander Wolf (alexwolf)]

@shankao I really want see log and description of behaviour for fresh installation of Stellarium. In the latest attached log I see few strange records, who shouldn't be here (I use version 0.14.2 on Ubuntu 14.04.4 from our PPA and I see difference).

[Alex Thompson (alexofdoom)]

@alexwolf

I built a version of stellarium from source following the instructions on the wiki and I still see the same behaviour (X hang after leaving fullscreen mode and going to windowed). I removed ~/.stellarium before running and I'll attach the log from this run.

Is there are way of increasing the debug level?

[Alexander Wolf (alexwolf)]

Are you can build it with flag CMAKE_BUILD_TYPE=Debug for cmake?

[Alex Thompson (alexofdoom)]

Yes, confirming that I built with 0.14.2.

I deleted the install and and build directory and started building with
'cmake -DCMAKE_BUILD_TYPE=Debug ../..'
after installing, I deleted the stellarium config ('rm ~/.stellarium') and ran stellarium with the -d option.

Pressing F11 to invoke windowed mode repeated the hang (or possibly a loss of focus/mouse and keyboard input?).

I have attached the log.

[Alexander Wolf (alexwolf)]

Please try build trunk: http://bazaar.launchpad.net/~stellarium/stellarium/trunk/tarball/8233

P.S. Stellarium hangs when running GLSL code and it may be bug in MESA (trunk has changes in GLSL code).

[Alex Thompson (alexofdoom)]

No hang when using the trunk build. This appears to have fixed the bug, although I'll try to play with it more to confirm that it doesn't re-appear.

Thank you for your help in debugging this issue.

[Alex Thompson (alexofdoom)]

Ok, it's not entirely fixed. I think I've seen two triggers for a hang

1) Switching to windowed mode from fullscreen (Now fixed)
2) Running for ~1 minute, either idle or with interaction (NOT fixed).

I've attached a log from case 2, still from the trunk debug build, with a clean ~/.stellarium folder.

[Alexander Wolf (alexwolf)]

Please try disable all plugins in ~/.stellarium/config.ini and check it again.
