Re: Bullseye: No MariaDB ODBC driver package

Thank you for the pointer, and I have done some further search and have found the Debian ODBC driver for MariaDB Tracker stating that there is a bug report in building this package for other platforms :shock:

Are there any other ODBC package alternatives to use with MariaDB?

Re: Bullseye: Dnsmasq not working

You're completely ignoring the fact that many other components in the system have changed between Stretch and Bullseye.

tvservice -o will have disabled the display output, and restarting lightdm is then asking to put a framebuffer on that disabled output which understandably fails. Thank you for the answer.
