Re: Ati Radeon Hd 7670m Driver Download 64-bit

I would like to play games with better performance than what I'm getting after updating to Kubuntu 16.04 LTS. Half the games are unplayable, sometimes to the level of nauseating due to low fps. I'm not entirely sure if my open-source radeon drivers are working as they're supposed to.
Ideally in a way that other software (like browser or IM) would still be running and kind of accessible. Like on a separate tty or something. In the really perfect case none of that would have any GPU performance spent on it (so not rendered I guess).
You can try downgrading xorg on 16.04 to version 1.16, which works with fglrx. I know this procedure works on 14.04.5, which got the 16.04 xorg version and kernel, but I have not tested or gotten any confirmation that it works on 16.04 as well.
Remember, I haven't tested this. I have gotten confirmation that it works on 14.04.5, but no one I know has tried it on 16.04 yet. It would be great if you are willing to test this. If you don't feel safe doing it, I will be happy to test in a virtual machine. (The fix if it doesn't work should be relatively easy: just reinstall xserver-xorg and the old version should be removed.)
I don't know if it'll help, but I had a similar problem (an ARM Chromebook, the nvidia Tegra K1 video driver it ships with works with up through like Xorg 1.16 or 1.17, not 1.18.) I held back to Xorg 1.15 since that is what was on the system (as well as the kernel), I suppose you should pick latest Xorg fglrx supports. I realized if I looked at the ubuntu 14.04.x lts-vivid, lts-xenial, whichever has the xorg you want, the packages it gives a pretty complete list of packages to hold to have a particular xorg+mesa stack going.
I held back the following packages (this locks them to the currently installed version), had a successful update to 16.04 with a running old Xorg and no complaints about dependencies; and luckily no systemd-related problems either.
I held these with (sudo or gksu) apt-mark hold (package name) before I did the upgrade. Since you are already on 16.04, I think you could get the older versions (Ubuntu 14.04's lts-wily packages have xorg 1.17, original 14.04 has 1.15), install with dpkg, and then hold the packages. You can unhold a package with apt-mark unhold (package name) and dpkg --get-selections grep hold lists what packages are held. If fglrx also needs an older kernel, it could be installed the same way.
I settled for the open-source drivers. I've gotten used to lower performance and I'm not interested of risking breaking everything. Also my performance drop might be due to an entirely different reason (hardware e.g.) which has yet to be explored.
