Every time I go to install anything in Crossover 14 or 15 on Scientific Linux 7.1, I get a notice that 3d graphics won't work. I'm not sure if I've messed up my config, but I have a nVidia GForce GTX760 which lspci sees, and I installed kmod-nvidia from ELRepo. lsmod | grep nvidia
nvidia 8642880 75
drm 349210 3 nvidia
i2c_core 40582 3 drm,i2c_i801,nvidia
From what I can tell (I'm not super familiar with 3d accelerated Linux, most experience is from servers and basic 2D GUIs) I have 3d acceleration working, but Crossover doesn't see it? Crossover also wants to install some packages every time I install a windows program.
openal-soft which is installed:
yum install openal-soft.x86_64
Loaded plugins: langpacks, nvidia
Package openal-soft-1.16.0-2.el7.x86_64 already installed and latest version
pulseaudio: yum install pulseaudio
Loaded plugins: langpacks, nvidia
Package pulseaudio-3.0-30.el7.x86_64 already installed and latest version
It also wants the 32 bit versions, but I don't know that they exist for SL7...
