How to use Unity and KDE concurrently?

I want to have Unity as my default desktop (CTRL-ALT-F7) and KDE as a secondary virtual desktop (CTRL-ALT-F8) so that I can run KDE applications like Quartus on it without messing with my typical setup.
From this question I'm under the impression that I could start a virtual desktop from a TTY with the following command:



startx /usr/sbin/lightdm :1 vt8


But I don't want to have to run a command in a TTY every time I boot, and that command fails with the following error anyways:



xauth: timeout in locking authority file /home/<user>/.Xauthority


Which was NOT fixed with rm ~/.Xauthority-* as per this answer.



My question is this: How can I get the secondary virtual desktop to start on boot?



I'm running Ubuntu 18.04 with ubuntu-unity-desktop and kubuntu-desktop packages installed. I can log out of my Unity session and switch to KDE and log in without problems.






linux ubuntu kde lightdm x

          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...
