## Logging Out and Back In

The group `video` doesn't show up in the group list,

```
$ id
uid=1000(arcologos) gid=1000(arcologos) groups=1000(arcologos),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),120(lpadmin),133(lxd),134(sambashare)
```

but now we get an additional line at the end of `clinfo` before it hangs.

```
ERROR: clCreateKernel(-6)
```

Next is to try adding to the `render` group, and then installing
`libnuma-dev` as recommended in the above GitHub Issue thread comment.

Here are some tips to check.

For example, you can verify that the groups exist and the user belongs to them

```
sudo cat /etc/group | grep $USER
```

You can also use

```
sudo addgroup $USER video
```

but this has the same effect as `usermod`.

You can also start a new shell where the user not only belongs to that group, but it is their
primary / login group (which seems a bit overkill).

```
newgrp video
```

This, however, still caused `clinfo -l` to hang with the new line `ERROR: clCreateKernel(-6)`.

Time to log out and log back in again.

## Add User to Render Group

This is the reference, the AMD ROCm manual, that instructs to add the user trying to access the
compute (CL) nodes to the `video` and `render` groups.
