 Posted: Thu Jan 07, 2016 10:40 pm Post subject: [SOLVED] OpenGL & Genymotion: failure to load swrast |
 |
|
Hi,
I recently upgraded my Gentoo system to the latest nvidia drivers, mesa, and genymotion (2.6.0). Now, whenever I launch genymotion, the player freezes when launching a VM, and I see the following in the console:
| Code: | $ genymotion
Logging activities to file: /home/tbowen/.Genymobile/genymotion.log
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Logging activities to file: /home/tbowen/.Genymobile/genymotion.log
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Logging activities to file: /local/.Genymobile/Genymotion/deployed/MyAndroidVM/genymotion-player.log
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast |
In addition to using the nvidia-drivers, I am also using KDE 4.11.19.
I noticed the new version of genymotion uses Qt5, if it makes a difference.
Any suggestions?
Thanks!

I reinstalled nvidia-drivers, but that did not help. I think there is some issue with either symlinks being messed up during nvidia-drivers ebuild or by genymotion's start-up ruining the LD_LIBRARY_PATH. Regardless, this fixed it for me:
| Code: | # cd /usr/lib64
# mv libGL.so.1.2.0 libGL.so.1.2.0.orig
# ln -snf /usr/lib64/opengl/nvidia/lib/libGL.so libGL.so.1.2.0 |
Genymotion popped up immediately after that. Actually, the symptoms are much broader than Genymotion. Any OpenGL application will produce the same errors, even something as simple as:
| Code: | $ glxgears
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 153 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 35
Current serial number in output stream: 37 |
The glxinfo command will also produce the same error. I used these commands to debug, and once they worked, genymotion worked again too.
Hope this helps someone else! |

sounds like it is trying to use mesa's opengl implementation.
what does the following say:
| Code: | | eselect opengl list |
should be set to nvidia in your case. |

Sorry, I had not documented that, but that was one of the first things I tried. I toggled it to xorg-x11 and then back to nvidia, but it made no difference. Here's the final value as we would hope and expect:
| Code: | $ eselect opengl list
Available OpenGL implementations:
[1] nvidia *
[2] xorg-x11
|
My current solution is definitely a hack, so if there is a way to fix this within the design and intent of the system, I'd much rather do that.
Thanks! |

See my thread here: https://forums.gentoo.org/viewtopic-t-1037122.html
You are probably using Mesa instead of nvidia-drivers libGL.so. See what these commands show for you:
| Code: |
# equery belongs /usr/lib/libGL.so
* Searching for /usr/lib/libGL.so ...
media-libs/mesa-11.0.6 (/usr/lib/libGL.so -> libGL.so.1.2.0)
media-libs/mesa-11.0.6 (/usr/lib/libGL.so.1.2.0)
# equery belongs /usr/lib/opengl/nvidia/lib/libGL.so
* Searching for /usr/lib/opengl/nvidia/lib/libGL.so ...
x11-drivers/nvidia-drivers-340.96 (/usr/lib/opengl/nvidia/lib/libGL.so.340.96)
x11-drivers/nvidia-drivers-340.96 (/usr/lib/opengl/nvidia/lib/libGL.so -> libGL.so.1)
# echo $LD_LIBRARY_PATH
# strings /etc/ld.so.cache | grep libGL.so
libGL.so.1
/usr/lib/opengl/nvidia/lib/libGL.so.1
libGL.so.1
/usr/lib/libGL.so.1
libGL.so
/usr/lib/opengl/nvidia/lib/libGL.so
libGL.so
/usr/lib/libGL.so |
I originally had an LD_LIBRARY_PATH defined that did not have /usr/lib/opengl/nvidia/lib defined, so was not using Nvidia's library. Erasing that uses the order in /etc/ld.so.cache, I think, so now it works for me. |

Ahh, good catch! I originally had PATH, MANPATH, LD_LIBRARY_PATH, LANG, LC_ALL, and LC_CTYPE in my ~/.bash_profile script. I wonder which of these I should delete in addition to LD_LIBRARY_PATH? I don't have any customizations except to add ~/bin to my user's path.
Thanks! |
