key repeat bug

If you're having a bug where the keyboard is glitchy in xorg Specifically keys are sometimes repeating it might be an issue with your clock source. There seems to be a problem with tsc on some amd systems.

Installing some massive bloated program and it's crashing a lot? OpenBSD uses pretty strict default open file limits for users. This can be checked with ulimit -a.

source and ports

Openbsd has three "flavours" - release - stable (release with security patches) - current

Make sure to keep ports and base in sync! List of cvs servers:
https://www.openbsd.org/anoncvs.html#CVSROOT

/usr/src

/usr/src is owned by the wsrc group so you need to add your user to that group before running the following commands. This can be done with:
user mod -G wsrc kota.

If you are following the 6.5 -stable branch using the USA mirror:

cd /usr
cvs -qd anoncvs@anoncvs4.usa.openbsd.org:/cvs checkout -rOPENBSD_6_5 -P src

Updating 6.5 later on:

cd /usr/src
cvs -q up -Pd -rOPENBSD_6_5

It does not destroy any of your local changes; rather it attempts to merge changes in.

ports

Make sure your user is member of the wsrc group and that /usr/ports is group writable by wsrc.

cd /usr
cvs -qd anoncvs@anoncvs4.usa.openbsd.org:/cvs checkout -rOPENBSD_6_5 -P ports

Updating ports:

cd /usr/ports
cvs -q up -Pd -rOPENBSD_6_5
