Here are some tips to get rid off some annoyances in Debian 7 aka Wheezy, Debian 8 aka Jessie and Debian 9 aka Stretch. Some of these annoyances also appear on systems that directly derive from Debian or are very similar to Debian, like Raspbian or Ubuntu.
pcspkr error message
Get rid off error message "Driver ‘pcspkr’ is already registered, aborting..." when booting: in /etc/modprobe.d/blacklist.conf create an entry "blacklist snd-pcsp"
exim4
Don't need a MTA? Deactivate it easily:
cd /etc/rc2.d mv S21exim4 K21exim4
The same way it's possible to deactivate all the NFS and portmapper crap.
Clearing screen on tty1
Debian 7
Since some time, Debian automatically clears the screen when the login prompt appears. This is especially annoying on tty1 because it vanishes all messages from the boot process. The solution is quite simple: in /etc/inittab find the line "1:2345:respawn:/sbin/getty 38400 tty1" and put a "--noclear" before "38400". Credits: man getty
Debian 8+ with SystemD
See SystemD
Setting video mode
Due to a bug in update-grub, GRUB_GFXPAYLOAD in /etc/default/grub is ignored. Two changes enable it:
In /etc/grub.d/00_header
if [ "x${GRUB_GFXPAYLOAD}" = "x" ] ; then GRUB_GFXPAYLOAD=800x600x32 ; fi
some lines later
set gfxpayload=${GRUB_GFXPAYLOAD}
Avoid PAM messages from CRON
In /etc/rsyslog.conf find section "RULES". Just before "auth,authpriv.*" insert
:msg, contains, "pam_unix(cron:session)" ~
In Ubuntu, this information is saved in /etc/rsyslog.d/50-default.conf.
After saving the file, restarting the service is required:
service rsyslog restart
Avoid "perl: warning: Setting locale failed."
This warning is displayed if you start "perl -e exit".
locale-gen dpkg-reconfigure locales
In the dpkg-reconfigure program, the language printed by echo $LANG must be selected.
Cron is not working correctly
- Symptoms: Jobs are not executed at all or print strange error messages on execution.
- Reasons: Cron does not have sufficient information where to find the programs/scripts specified (missing PATH) or the wrong program is used to execute scripts (i.e. sh instead of bash).
Insert these lines at the header of your crontab file (always edit it with "crontab -e", set EDITOR environment variable when needed):
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin SHELL=/bin/bash
Text-based console cannot show UTF-8 characters
dpkg-reconfigure console-setup
