lumanet's questions

I have connected my Blu-Ray disk drive via a SATA -> USB adapter to my notebook. But is not found as optical disk drive by the system. When I type in

lsusb

it shows:

Bus 004 Device 005: ID 152d:0578 JMicron Technology Corp. / JMicron USA Technology Corp. JMS567 SATA 6Gb/s bridge

And when I do: dmesg | grep usb

I get this:

As far as I can see it is recognized as a hard disk drive. Is there a way on linux to change this or is it because of the adapter/ bridge and can not be changed? (In the last case I would of course purchase a new one. Anything I have to pay attention on?)

I have a very specific problem with Kmail. I cannot login to one of my imap mail accounts. 3x other imap mail accounts are working perfectly but not that one. I first thought it might be the mail account, but when I tried it on a fresh Kubuntu vm installation it worked also with that mail account.

So I thought it's most likely because of some wrong configuration. Unfortunately I didn't find a way to completely purge my Kmail, Kontact and Akonadi configuration and databases. All my attempts failed so far.

I have already tried the following:

1. removing:

rm -r ~/.config/akonadi*

rm -r ~/.local/share/akonadi*

apt purge --auto-remove akonadi-server

2. stopping some services with:

akonadiconsole

I tried to remove some of the services (like "local folders"). This didn't help either.

When I start "Kontact -> Kmail -> Settings -> Configure KMail" I still see the old Identities. So I guess not all the data (configuration or database) is removed. How do I completely remove all the configuration and databases and do a fresh Kontact reinstallation.

All in all my system is working quite well so I would like to avoid a complete Kubuntu reinstallation.

Thank you for your help. :)
