Installing CUDA automatic reinstall Nvidia driver

cn flag

I am using Ubuntu 20.04 with nvidia gpu. From driver list I can select nvidia driver version 510, but when I try to install cuda version 11.2 (new version is CUDA 11.6). During the install, it will reinstall nvidia driver version 460. Which will happen next is I can not use multiple monitors with version 460. Multiple monitors work well with Nvidia version 510.

dpkg: error processing package cuda-drivers-460 (--configure):
 dependency problems - leaving unconfigured
Setting up libnvidia-encode-460:amd64 (460.32.03-0ubuntu1) ...
No apport report written because the error message indicates its a followup error from a previous failure.

dpkg: dependency problems prevent configuration of cuda-drivers:
 cuda-drivers depends on cuda-drivers-460 (= 460.32.03-1); however:
  Package cuda-drivers-460 is not configured yet.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
