view story

http://crunchbanglinux.org – i've installed Linux Mint 13 LTS (XFCE) on this rig, and 99% work fine OOTB (WiFi, Dropbox, Skype, ...). even XFCE compositing works great.i only run into trouble when trying to launch OpenGL applications like Stellarium, Google Earth or glxgears. these problems remain even with compositing turned OFF.glxgears gives me a "Segmentation Fault" message only, while Stellarium provides a few more details:Using default graphics system specified at build time: raster ------------------------------------------------------- [ This is Stellarium 0.11.0 - http://www.stellarium.org ] [ (HowTos)
