Just did that.
I had earlier tried to move to bullseye - but a glade problem got in my way -
So just 2 days ago - I first upgraded from buster to bullseye - then bullseye to bookworm - installed linuxcnc from the
debian repository.
Good overview of upgrade at
https://www.debian.org/releases/bookworm/amd64/release-notes/ch-upgrading.en.html
Tells you how to clean out cruft before hand.
Only had a couple of minor problems - I had to reinstall a customized component - and fix a hal line that it didn't used
to complain about. There was a missing '(' in the old copy of hitcounter.py
What really made me smile is gladvcp just worked!
I run under kde - so I disabled the search indexing engine and other fluff.
You can run htop - before the desktop starts - go over all the tasks that you
probably don't want.
You can disable tasks with systemctl disable task-name
# cat /sys/module/apparmor/parameters/enabled Should return N if you get it
disabled -
You will want to disable apparmor.
You need to set a kernel paramater.. My line looked like this (a four core
machine)
GRUB_CMDLINE_LINUX_DEFAULT="quiet text isolcpus=2,3 apparmor=0"
isolcpus makes a difference as well.
This is with three copies of glxgears running:

Of course, latency is not so important is you are doing counting in hardware
(think Messa)..

Any one installed Debian 12 and running Linuxcnc on a machine? Since Linuxcnc
is now in Debian Stable, I was wondering if anyone cared to voice their
opinions about installing and running Linuxcnc that way.
I have a machine that I am starting to refit and I am considering trying to
install that way rather than using one of the more obsolete Linuxcnc ISOs.
