    Linux kernel driver


      I am installing the latest driver for my video card and its been an adventure. I am using Kubuntu 16.06. I know its not supported but any way. I have successfully got X working with the new driver except for one part. I can't find the kernel driver. I have the X driver and modules installed correctly. The kernel is looking for the frglx.ko file and I can't find it anywhere on my system. Any Ideas?

              This looks like same problem which has been solved with a patch by nenad for catalyst driver.

              Try heading over here:


              there are links to patches and plenty of discussion if you scroll down. There are also previous posts on same site regarding previous kernels.

              The one must is that you will have to downgrade your xorg to 1.17 or earlier.

              The good news is that crimson driver is working with xorg 1.16 and 1.17 on kernel 4.6.7 on Fedora 23 and Fedora 24. So if you can patch the driver you may well be able to get some sucess on Ubuntu.
