After rebooting I get this in the output of xrandr:



HDMI2 connected (normal left inverted right x axis y axis)
 1920x1080 60.00 + 50.00 59.94 24.00 23.98


I then try to set it up:



xrandr --output HDMI2 --mode 1920x1080 --right-of eDP1


At this point nothing happens on the external screen, my main screen just flickers once, and when I run xrandr again I get this:



HDMI2 disconnected 1920x1080+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm


If I then restart X or reboot I get back to square one.



In the systemd journal I see a possibly related issue:




i915 0000:00:02.0: HDMI-A-2: EDID is invalid:




(It's probably worth noting that it does not say that the EDID checksum is invalid)



I've tried deleting ~/.config/monitors.xml and rebooting, but with no luck.

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...
