To get bitmapped fonts to work I had to edit /etc/font/local.conf, there is a comment which states what to do. Then I just had to restart xfs, also I read somewhere that it was a good idea to run fc-cache.
I am really fond of the Terminus fonts for terminal applications and emacs (package: xfonts-terminus).
The problems are that the upper button in the middle do not work and the track pad allows tapping. First, I used gpm with an updated synaptics driver to handle input, but this did not work without problems. The real solution is to use the Synaptics Touchpad Driver for XFree 4.x. (http://w1.894.telia.com/~u89404340/touchpad/).
I now have the following in my XF86Config-4:
Load "synaptics_drv" Section "InputDevice" # using the X module Identifier "Synaptics Mouse" Driver "synaptics" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" # absolute area: 0-6143 in both directions Option "LeftEdge" "1700" Option "RightEdge" "5300" Option "TopEdge" "1700" Option "BottomEdge" "4200" Option "FingerLow" "25" Option "FingerHigh" "30" Option "MaxTapTime" "180" Option "MaxTapMove" "220" Option "VertScrollDelta" "100" Option "MinSpeed" "0.06" Option "MaxSpeed" "0.12" Option "AccelFactor" "0.0010" Option "SHMConfig" "on" Option "TapButton1" "0" Option "TapButton2" "0" Option "TapButton3" "0" # Option "Repeater" "/dev/ps2mouse" EndSection
It works pretty well (no tapping, and all buttons work).
There are problems with radeon 3d and suspend, some solution might be here: http://cpbotha.net/dri_resume.html
Secure the installation: http://www.debian.org/doc/manuals/securing-debian-howto/index.en.html
If using testing, set up sources.list to use:
deb http://security.debian.org/ woody/updates main contrib non-free
Clean up old packages and stuff with: apt-get clean
The interface (dialog, editor etc.) used to configure packages is part of the condiguration of debconf, so it can be changed with:
dpkg-reconfigure debconf
deb http://www.debian-multimedia.org stable main
to sources.
I was using testing, but when it became stable I would like to follow stable for a while. The problem was that some of my packages was already upraded to the new testing and that meant that many installs and upgrades was impossible. The solution was simply to put the following in /etc/apt/preferences:
Package: * Pin: release o=Debian,a=stable Pin-Priority: 1001
And do a apt-get dist-upgrade. It worked well (but no critical packaged needed to be downgraded however).
Note: Debian will only downgrade if priorities exceed 1000, that is why 1001 works.
Find the version of the package that you want to install. Often this will be in /var/cache/apt/archives if the new package was only recently installed. If not you can often get the old package from a mirror. Look under pool in the mirror eg [mirror]/pool/[packages].
Use dpkg -i package.deb for install the new lower version.
If there are dependencies on the newer version the package won't install. You have a choice of either forcing the install or downgrading the dependencies as well.
Backports of newer packages to Debian: http://backports.org/
Set up the different sources in /etc/apt/sources.list and make priorities in /etc/apt/preferences. (Explained in apt_preferences(5), http://jaqque.sbih.org/kplug/apt-pinning.html, and http://www.argon.org/~roderick/apt-pinning.html)
Example from apt_preferences(5) to track stable:
Explanation: Uninstall or do not install any Debian-originated
Explanation: package versions other than those in the stable distro
Package: *
Pin: release a=stable
Pin-Priority: 900
Package: *
Pin: release o=Debian
Pin-Priority: -10
Still, it is possible to use testing:
apt-get install <package>/testing
This will sometimes fail with a strange error message (something with "broken packages"). The following works better as it sets the target-release to testing:
apt-get -t testing install <package>
If backports is used, do something like:
apt-get -t sarge-backports install <package>
Use -s to check versions etc.
Find out which packet a file came from:
dpkg -S <path-and-filename>
Info about package:
dpkg -p <package>
Find out which packages are installed:
dpkg --get-selections dpkg --set-selections
List all packages starting with emacs: dpkg -l 'emacs*'
Show files in the package slashem-common: dpkg -L slashem-common
Show status: dpkg -s slashem-common
Setting hold from the command line (so it will not be upgraded):
# echo slashem hold | dpkg --set-selections
Upgrade later with:
# echo slashem install | dpkg --set-selections
(Re)configure a package with:
dpkg-reconfigure <package>
Install a package directly:
dpkg -i <package.deb>
Together with /etc it is a good idea to backup the package listing and the DebConf-base:
# dpkg --get-selections > pakkeliste.backup # debconf-get-selections > debconfdb.backup
Restore with:
# debconf-set-selections < debconf.backup # dpkg --set-selections < pakkeliste.backup # apt-get dselect-upgrade
Alsa, if sounds stops working try to reconfigure as root with =alsaconf=.
Tcpa on linux: http://www.research.ibm.com/gsal/tcpa/
Xine codecs, find them on the mplayer download page, install anywhere and update .xine/config with something like decoder.external.win32_codecs_path:/opt/win32codecs/ -- this can also be done from within xine (config->decoder).
mkisofs and frontends like growisofs will merge content if multiple paths are given as pathspecs, e.g.:
mkisofs -J -r -o image.iso /etc /root /opt
will throw the content of /etc, /root, and /opt into the root of the disk.
Graftpoints can be used to keep the structure on the disk or image:
mkisofs -J -r -o image.iso -graft-points etc/=/etc root=/root opt/=/opt
this will make an image with the three dirs at the top level. This approach will place the specified dir at the exact point, e.g. etc/=/etc/apt will place the content of /etc/apt in /etc and not in /etc/apt -- that requires etc/apt/=/etc/apt etc.
