User talk:Rebhana

The following is a compilation of modifications I applied to my personal installation of Easy Debian and which I suggest(ed) for inclusion in the next versions of debian-m5-XX.img.ext2 and the easy-deb-chroot package.

(This is essentially a writer's digest of my contributions to the thread Easy Debian Fremantle Beta Testing - discussions should continue in the above talk thread, not here, please.)

My current Easy Debian Installation
After installing easy-deb-chroot 0.9.50-1fremantle1 from Extras and extraction of image debian-m5-v3d.img.ext2 I have applied the following fixes and additions:

(Filenames prefixed by $CHROOT refer to files in the image. Within the Debian chroot $CHROOT is to be omitted; in Maemo $CHROOT=/.debian - read the Easy Debian wiki to educate yourself before proceeding blindly!)

Keyboard focus fix
Change $CHROOT/usr/bin/xephwm5 so that the lines containing qobi-wmhint-fix and set-focus read: sudo /sbin/qobi-wmhint-fix $PARWIN
 * 1) /usr/bin/set-focus $PARWIN

This resolves all issues with keyboard focus loss in LXDE for good. (The newer easy-deb-chroot version in Extras-devel achieves the same through Maemo-side scripts.)

Some, but very few, applications have problems with keyboard focus when run under debbie (while running without problem in LXDE). This is solved by qole's new script /home/user/.kbdactive in the devel version of easy-deb-chroot (invoked by Fn+Return when "Set Deb HW Keys" is activated).

debbie-sue
I prefer debbie-sue over debbie, so I changed /usr/bin/debwm: fixkbdfocus "N/A Easy Debian" if [ "$?" = 2 ] ; then debbie-sue xephwm5 fi

brighter theme
While the MurrinaNightOrange theme is really cool, I found it made some applications (in particular zim) almost unusable. To change the theme to something more standard, I produced the file

/home/user/.gtkrc-2.0.mine with content gtk-theme-name="Raleigh"

In both configuration files in /home/user/.config/lxpanel/LXDE/panels I changed transparent=1 to have nicer looking panels after the change to brighter themes in the applications.

fixing sound
In one XTerminal: debbie xmms2d -o pulse Then in a second one: debbie lxmusic

Key bindings
/home/user/.xbindkeysrc "xbindkeys_show" control+shift + q


 * 1)  "wmctrl -r :ACTIVE: -b toggle,fullscreen"
 * 2)    m:0x4 + c:111
 * 3)    Control + Up

"wmctrl -r :ACTIVE: -b toggle,fullscreen" Shift+Mod5 + space
 * 1)  "wmctrl -r :ACTIVE: -b toggle,fullscreen"
 * 2)    m:0x4 + c:65
 * 3)    Control + space

"xvkbd -xsendevent -text '\t'" Control + KP_Enter

"xvkbd -xsendevent -text '\e'" Shift+BackSpace So I changed the binding of full screen toggle to Shift+Fn+Space (which otherwise conflicts with Maemo key bindings) and added additional ones for tab (\t) and escape (\e).

Security updates
After adding security updates to $CHROOT/etc/apt/sources.list: deb http://security.eu.debian.org/ lenny/updates main contrib non-free and disabling lenny-backports, I did a full upgrade by apt-get update apt-get upgrade apt-get clean (without subsequently upgrading manually the packages that were held back when doing so).

Additional packages
In order to have more space in the 2GB image, I have moved $CHROOT/usr/share/doc and $CHROOT/var/cache/apt/archives to /home/user and provided symlinks. From debian chroot: cd /usr/share cp -a doc /home/user/.easydebdoc rm -r doc ln -s /home/user/.easydebdoc doc cd /var/cache/apt apt-get clean cp -a archives /home/user/.easydebarchives mv archives archives- ln -s /home/user/.easydebarchives archives

I personally found the following packages useful, which include a complete LATeX installation and the symbolic math program xmaxima, which both are fairly big.

(Don't forget to run "apt-get clean" regularly to free the space occupied by the downloaded Debian packages once they are installed.)

From lenny :


 * encfs (see also wiki)
 * mc
 * odt2txt
 * openssh-client (see also wiki)
 * pgpgpg
 * rsync
 * tree
 * vpnc (see also wiki)
 * xmaxima (screenshot here)
 * wxmaxima (through "apt-get -t lenny-backports install wxmaxima"; screenshots)
 * dvipng
 * graphviz
 * bzr
 * texlive-latex-base
 * texlive-publishers
 * prosper
 * latex-beamer
 * grace
 * djview4
 * pdftk
 * flpsed
 * xpaint

Then with squeeze activated: (generally using squeeze only when I really wanted newer versions)


 * galculator
 * geeqie
 * gramps (needs debbie-sue in lieu of debbie!)
 * pdfgrep
 * sshfs
 * xournal
 * zim (see also wiki)
 * cadabra (computer algebra system for field theorists - pulls in new texlive installation (big!) and requires additionally texlive-latex3 - screenshot)

Upgrade of OpenOffice to 3.2.1 (including also openoffice.org-math, but leaving out openoffice.org-base which does not work in armel):

apt-get install openoffice.org-writer openoffice.org-impress openoffice.org-calc openoffice.org-math openoffice.org-style-crystal openoffice.org-style-galaxy openoffice.org-style-hicontrast openoffice.org-style-tango openoffice.org-emailmerge ttf-opensymbol python-uno apt-get clean

Then revert $CHROOT/etc/apt/sources.list back to lenny only. Besides being on the safe side for future installations, this also frees quite some memory in the image.

See the wiki for more details on some of the above applications!

Other Debian applications I tested
... but which are not in my final image, because of lack of space, lack of need, or other reasons:

Fully working:

 * from lenny
 * gcalctool
 * gftp
 * gnumeric
 * gqview (superseded by geeqie in squeeze)
 * kile
 * sweep (powerful sound editor, which however sometimes fails to open audio device)


 * from squeeze
 * build-essential
 * pdfchain
 * qalculate

Unresolved problems:

 * abiword
 * needs to be installed from squeeze, works, but because gconf2 is upgraded interferes with configuration of other applications such as evince


 * calibre
 * Does not start. Inconsistent python installation?


 * eric
 * Installable from squeeze provided libpulse0 is upgraded (breaks sound in Easy Debian, however)
 * Only works in LXDE; when started with debbie or debbie-sue, does not get keyboard focus. UPDATE: works also in debbie with the simple .kbdactive script that is included in the new version of easy-deb-chroot in extras-devel (and mapped to Fn+Return in xbindkeys).

The rest of this page refers to older versions of easy-deb-chroot and older images.

Proposed changes to easy-deb-chroot 0.9.46-1fremantle1
UPDATE: Almost all of it now in easy-deb-chroot 0.9.50-1fremantle1 in Extras-Testing. "su -" is not made the default behavior of debbie (yet), but there are two new scripts "debbie-sue" for running debbie with "su - user" implicit, and "debsu" corresponding to "debian su -".

PR 1.2

 * PR 1.2 keyboard fix (/usr/share/applications/hildon/lxdefocus.desktop)

su -
(assumes that /etc/profile is amended as in images v3c and later)

/usr/bin/debbie: add hyphen in two lines: sudo /sbin/debian su - ...

Some applications do not work properly without that (zim), others fail in LXDE (gramps), and internationalization works better in debbie and /sbin/debian that way (the Maemo environment variable LANG does not include ".UTF-8").

It would however be necessary to communicate this change to users of images up to v3b, so that they insert the necessary environment variables for openoffice and GTK_MODULES into /etc/profile.

Also in debchroot.desktop change to:

Exec=osso-xterm "sudo debian su -"

I don't think it's necessary to introduce a script with a different name that just differs in the "-" option. The old behavior would still be accessible through "sudo debian su" and "sudo debian su -c" if ever needed, though so far I have not found a case were this was needed. For ordinary users (in particular non-English ones), I believe the "-" option should be the default.

.xbindkeysrc

 * delete spurious first lines
 * include "-xsendevent" in all "xvbkd -text" calls (in my experience needed to make F1-F12 work reliably)
 * add tab and escape, too:

"xvkbd -xsendevent -text '\t'" Control + KP_Enter

"xvkbd -xsendevent -text '\e'" Shift+BackSpace

For additional shortcuts: the Fn+Shift-combination (Shift+Mod5) is usually free. Perhaps this should be used also to replace Shift+Space and Shift+Up for full-screen toggle, since these two combinations are also already in use for N900 Shortcuts and Gestures.

Another suggestion is to include the information about F1-F12 key bindings in the "Information" window of LXDE together with the instruction to first press Fn and then rock the thumb down to Shift (zenity line in /usr/bin/xephwm5that in the image ).

/usr/bin/xephfocus
UPDATE: xephfocus no longer needed by new Easy Debian package

Check for "N/A $WMNAME" instead of only $WMNAME. Otherwise browser windows with Easy Debian in the title might be picked. export PARWIN=`wmctrl -l | grep -i "N/A $WMNAME" | awk '{print $1}'`

Include title option to fix "Info bug": zenity --display=:0 --info --title="Information" --text="This window is needed to gain keyboard focus in LXDE. Click OK." &

Proposed changes to image debian-m5-v3b.img.ext2 (old)
UPDATE: All the issues addressed below are fixed in the new image (v3d). If you don't want to re-install, you can find here what's required to fixing a v3b-installation yourself.

Better internationalizability

 * change /usr/bin/xephwm5 such that:

zenity line now has --title Information clause to force dialog title to not change per locale (safer: covers all locales)

original suggestion:

export TWOWIN=`wmctrl -l | grep -i Info | awk '{print $1}'`

This covers languages bs, ca, cs, da, de, en_CA, en_GB, es, eu, fr, gl, hr, hu, id, it, lt, lv, nb, nl, nn, pl, pt, pt_BR, ro, sk, sq, sr@Latn, sv


 * don't enable sticky keys hack by default

therefore in /etc/xdg/lxsession/LXDE/autostart comment out:


 * 1) xkbset exp 60 =sticky =twokey =latchlock
 * 2) xkbset sticky -twokey latchlock

Preparation for "su -" in future /usr/bin/debbie

 * Add

export GTK_MODULES=libgtkstylus.so export SAL_USE_VCLPLUGIN="gtk" export OOO_FORCE_DESKTOP="gnome" export SAL_NOOPENGL="true" export OOO_DISABLE_RECOVERY="true" export SAL_DISABLE_SYNCHRONOUS_PRINTER_DETECTION="true"
 * 1) Messy hack to make tap-and-hold work with GTK apps.
 * 1) Some OpenOffice environment variables
 * 1) export SAL_DISABLE_CUPS="true"

to /etc/profile

PS1='deb:\w\$ ' into /etc/profile. Remove any $PS1 setting from /root/.bashrc.
 * Instead of "PS1='\u@\h:\w\$ '" I also suggest to put I

v3c: Implemented differently: get partition ID from blkid, like chroot script
 * In order to work also with "debian su - user" needs full path "/sbin/blkid" in /etc/profile !
 * $PS1 setting should (still) be removed from /root/.bashrc, so that prompt is not overwritten when one does "debian su -" (needed for having full localization also for root)

packages

 * evince
 * does not show up in LXDE menu. For that it needs "NoDisplay=false" in /usr/share/applications/evince.desktop followed by

xdg-desktop-menu install --novendor /usr/share/applications/evince.desktop


 * make evince also display postscript files
 * I noticed that installing "gv" pulled in the required packages (psfontmgr perhaps?) to display postscript files also with evince


 * extra packages
 * are of course not needed, since everyone can install them themselves. The following packages are however small enough to consider having them added: less, rsync . Slightly bigger but extremely useful: openssh-client (wontfix), cups-client


 * xbindkeys
 * man pages are missing, but would be desirable I think. Simply re-install xbindkeys.


 * /var/run/onfirstchroot.rc script might have xbindkeys started by default. But that does interfere slightly with Maemo. For instance, Shift-Space under Maemo is a language toggle, which is then turned into a full screen toggle until closechroot is executed.

Sound
Not sure whether fixing sound by debbie xmms2d -o pulse and then starting lxmusic fixes the configuration stored in /home/user or in the image. If in the latter, this could be fixed in the image.

Minor cleanups

 * /etc/hosts aliases localhost to Nokia-N800-23-14. Since the 2GB image doesn't work for Diablo (true?), this should be changed to Nokia-N900-42-11 perhaps.


 * xephwm5 produces (harmless) error "trl: command not found"


 * /var/log could be cleaned. Since no syslog is started (correct?), auth.log, bootstrap.log, daemon.log, debug, kern.log, lastlog, messages, scrollkeeper.log, syslog, user.log contain only obsolete messages from before the image was created and could be emptied (frees a few MB)


 * are the files in /root used at all (another MB)


 * /etc contains a number of files ending with "." or ".MonSep8"


 * /etc/passwd contains (encrypted) root and user passwords


 * /var/backups/ could be emptied


 * /etc/mtab fixed to make "df -h" work (thanks hstende)
