When I boot Deepin 15.7, that I recently installed, it for some reason seems to refuse to show anything onscreen without a HDMI connection.



NOTE - It shows GRUB, then when I select Deepin and log in, the cursor does a load and then the screen switches off until I connect HDMI.



I suspect it's in the settings, since it began when I was messing and rotated the screen.



There are many questions like this, but they relate to Nvidia GPUs, which are not relevant to me, and this is is not a first boot.



Any help?

          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...
