A cursory scan found no DRI drivers. DRI drivers are needed to get the full OpenGL performance and functionality. Their absence can cause OpenGL to be reported as not working, and prevent games and productivity applications alike from working properly.
Installing the Mesa DRI drivers may fix this issue. ++color:cyan++However if you use the proprietary AMD or Nvidia drivers you may need to install other packages.++
On CrossOver 17 and greater, the simplest solution to fix this issue is to run:
The ++color:cyan++commands usually also apply to newer versions of the distributions above as well as derived distributions++. So for instance a fix for Debian 7 may still be valid for the latest Debian Testing and is typically also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora likely also works on Red Hat Enterprise Linux, CentOS, etc.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
