I just switched from GNOME to KDE5 (with its default display manager) on Debian 9 by issuing:



apt-get install kde-full
apt-get purge gnome*


Now no windows are shown. I can launch the application menu but as programs open no window is shown.



What went wrong?






debian kde5

  • Though I don't know why, that's the window manager not starting. If you can start applications, you can try to start a console and run kwin manually. See if it works, and if it doesn't look at the errors.

  • I can start applications but i cannot see the windows... is there any shortcut to open a "run a command" windows in which i can easily type without seeing?

  • If krunner is launched, Alt+F2 opens a small box from where one can run commands, starts applications, find windows or trigger events. But it's odd, you mean you see nothing at all or you don't see window borders?

  • I don't see anything except the applications if i hover with the mouse on the application bar and the application launcher. So I can type in a terminal and kind of see the output.

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...
