    I found one thread about it https://devtalk.nvidia.com/default/t...37310/#3737310


    if you wanted to play with your pc, you would have to buy a pc with intel

      RadeonSI is only the newest generation. Everything else should work just fine.

      Also, if X doesn't start, you have a bug and should report it. Any error messages? If it is an llvm assertion error you might want to do it with
      Code:
      startx &> startx.log
      because as far as I'm aware those are only printed to stderr and not to a logfile.

        With a mid or high end AMD CPU, it's rare to be actually CPU limited in games (if it is the case, blame the game devs).

          mmm it looks like outdated software, remember for radeonSI you need daily bleeding edge code, meaning

          kernel 3.10-rc1[for UVD]
          glamor git
          llvm svn
          mesa git
          xf86-video-ati git
          pixman git[helps]
          cairo git [helps]
          xorg 1.12 or better
          libdrm git

          if you are using ubuntu or derivates you need to find a PPA if you are confortable with source distros Gentoo is quite good

            what are you talking about?
            intel graphics?

              overlayfs?

              What about overlayfs wasn't it proposed for inclusion in 3.10?

                  for playing with unstable kernels, you don't need any dedicate graphics, with an intel hd4000, is fine.

                    1) 3.10.0-rc1 is a release candidate, not "unstable" at all. Hell, I've been running release candidate kernels since December on my [b]Primary[b/] Workstation+Gaming rig and haven't had any instability at all.
                    2) I don't own any intel cpus, haven't since my atom died, my pentium e4300 was outdated, and my P3-550MHz Katmai was retired.
                    3) I like to game. I also own SSDs and other cutting-edge hardware. Why would I want to be stuck in 2012 (or 1979 without a GUI)?

                      That means that there are heavy threaded applications assigned to virtual cores which makes the cpu running 24/7 on turbo mode, thus making the cpu a fryer.

                      My 4c/8t intel suffers less heat on win7 with debian or kali or backtrack in a virtual machine.
                      There are options to control that. By using the HT on one core it can shut down the other three cores, which can save power. Or in some cases improve performance by allowing high levels of turbo.

                      If you don't like using turbo then you can set the maximum allowed clock speed to a lower value. It is one of the files under /sys/devices/system/cpu I am pretty sure.

                      If you'd like to spread the jobs around the cores mess with:
                      'sched_smt_power_savings' tunable under /sys/devices/system/cpu/
                      controls the multi-threading related tunable. By default, this is set to
                      '0' (for optimal performance). By setting this to '1', under light load
                      scenarios, the process load is distributed such that all the threads in
                      a core and all the cores in a processor package are busy before
                      distributing the process load to threads and cores, in other processor
                      packages.
                      And finally, if your CPU cannot take the heat of running at full load or at full turbo then your cooling system is inadequate and you should fix it. Intel CPUs will control themselves and not burn out unless you disabled the thermal protection system somehow so really that should not be a problem. I even seem to recall an article about running an Intel 3770 with a small heatsink and no fan, just to show that it is possible. Worked fine except for slowing itself down quite a lot.
