The Mesa drivers only support OpenGL 4.5 Core mode, they don't support OpenGL 4.5 Compatibility mode. It's odd but for some reason they only support OpenGL 3.3 Compatibility mode, and the developers have stated they don't intend on changing it. So games and other software that require higher Compatibility modes will never run on Mesa.
There are some environment variables, MESA_GLSL_VERSION_OVERRIDE and MESA_GL_VERSION_OVERRIDE, that make the drivers report a higher compatibility mode but since the underlying functionality is still missing they don't work. In any case I have a Sapphire Nitro R9-390 so I'm trying to work out a deal a crypto-miner to exchange it for an Nvidia GPU. Unfortunately AMD is only fully functional for crypto-mining under Linux at this time, and since AMDGPU-PRO will be a mess for the next few years and the open source drivers will never be fully functional I'm giving up on AMD. Thank you for your help but I've lived with a crippled GPU for almost a year now and I have to acknowledge there's no viable option left other than surrender. It's not Ubuntu's fault, AMD simply abandoned its loyal customers. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libepoxy in Ubuntu. https://bugs.launchpad.net/bugs/1698233 Title: New libepoxy0 causes hang at boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libepoxy/+bug/1698233/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
