I have a Minix Z83-4 media PC. First thing I did was installing Linux Mint (cfxe desktop) and I did a kernal update (because sound was not working) to 3.16? IIRC



I am having the problem that my TV does not get an HDMI signal after I turn the TV off and on. I have to reboot the Minix if I want my screen back. If I first turn the TV on and than the computer there are no problems.



This problem only occurs when I am logged in to the desktop environment.
If I am at the login screen, I can turn off/on the TV without problems.
As soon as I log in, the screen turns black and it has no HDMI signal.
Opening a virtual terminal (Ctrl + Alt + f1) also gets me an HDMI signal.



The TV has 4K resolution but I am working at half the resolution. Both the login screen as well as the virtual terminal are however at this 4K resolution (which is the default resolution) (You can tell by the extremely small texts). When I login to the desktop the reso gets set to my desired settings.



I am desperate for a solution.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
