Stellarium Issues

Hello. I'm having issues getting Stellarium running on my Acer Aspire 5536-5519. I'm running 5.5 with the 3.0.0-20-generic-pae kernel, have compiz enabled, and tried libgl1-mesa-dri-experimental. The system has Mobility Radeon HD 3200 Graphics.
Thanks for your time!
Do you really have 3D acceleration? I doubt it is even possible on such an AMD system. To check it:
$ glxinfo | fgrep rendering
Hello. After install of mesa-utils. $ glxinfo | fgrep rendering Direct rendering: Yes
No error messages. The application is relatively slow to load and is very slow functioning. Example: Moving from east to south with the cursor is delayed and choppy.
I am afraid there is not much to do beyond considering buying another computer with an Intel graphic chipset. The free drivers for AMD cards are not very efficient. I am even surprised that you could get 3D acceleration.
Not surprising, direct rendering is also available with the software
rasterizer, other values should be used to find it 3d acceleration works
(although there would be no issue if it worked).
I obviously need to update my knowledges. So, you tell me that on a modern GNU/Linux, the direct rendering is always true whatever the graphic driver. Even with vesa? How to know whether 3D acceleration is enabled?
There is a variable to disable 3d acceleration for a program:
diff -u <(LIBGL_ALWAYS_SOFTWARE=t glxinfo) <(glxinfo)
[...]
-OpenGL vendor string: VMware, Inc.
-OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
+OpenGL vendor string: nouveau
+OpenGL renderer string: Gallium 0.4 on NV46
[...]
(Omitted many lines with different extensions or visuals.)
So I would trust the vendor and renderer strings more. Not tested them
on other machines.
Very good. Thanks for your help! Stellarium runs quite well on my eepc, but I guess I'm out of luck with the Acer. Thanks again.
