looks like a driver issue to me.
as you can read in the log ps fails to open the x window because it cannot create an OpenGL2D context
this can have several causes, the most common ones are(in no particular order):
- your graphics driver isn't installed properly
- you have the wrong graphics driver installed
- your X configuration is wrong
- your graphics driver is too old
so your best bet will probably be to reinstall/update your graphics driver.
if it doesn't help, you should verify it's actually installed properly:
ldd `which glxgears` -> libGL.so should point to the right one
glxinfo | grep direct -> should say direct rendering is enabled
glxgears -> you should see some rotating wheels and in the terminal get a decent amount of FPS (I'd say 3000-5000 as a minimum, but don't nail me on those values)
especially with multi-arch systems, it commonly happens that libGL for one arch points to the wrong one.
in this case do ldconfig
also you should make sure that your installed graphic driver actually supports your graphic card (e.g. open source drivers may not support the latest cards and binary drivers may not support very old cards)
finally in case your X configuration is wrong: I'd say it's best if you consult a help channel of your choice - preferably for your distribution - to get some help
additionally something seems wrong with your audio configuration. you may want to check this as well
kind regards
