Into.the.Void.

Lately I noticed some image distortion appearing on some websites using my laptop with Debian squeeze. Menus on swiftfox did not appear as they should, some logos appeared out of their place and there were artifacts and other annoying things. For example Planet Gnome looked like this:

When using iceweasel 3.0.12 everything looked fine. Then I followed a guide to install Iceweasel 3.5 from experimental to my system. Images looked distorted again. So there must have been a problem with the latest xulrunner….

After some googling I bumped into Debian bug #491871 – [965GM EXA] display corruption with xulrunner 1.9. Following post #67 on that thread I was able to repair my xorg.conf to something that fixed the image distortion. Now Planet Gnome looks like this:

One of the things that good Linux applications should have is uniformity. Just like Mac OS X does. All applications should use the same keybindings to perform the same tasks. For example, on _every_ OS X application, in order to quit it you have to press “CMD+Q”, it’s that simple and everybody follows it. Everybody. On Linux though there are some applications that simply don’t care about uniformity. One of these applications is smplayer.

While it is almost standard for Linux applications to quit using Ctrl+Q, smplayer simply doesn’t have this option. It has the option of closing the current video with Ctrl+X but it doesn’t have the simple option of quitting using a keyboard shortcut.

So, the next (oneliner actually) patch does simply what I described above. It makes smplayer quit using “Ctrl+Q”.

The screenshot that shows what the patch does:

smplayer-0.6.8-quit.patch:

+ quitAct = new MyAction(QKeySequence("Ctrl+Q"), this, "quit");
connect( quitAct, SIGNAL(triggered()), this, SLOT(quit()) );
openMenu->addAction(quitAct);

And a patched ebuild for smplayer-0.6.8 to use this minor patch (only one line is added to the ebuild):
smplayer-0.6.8-r1.ebuild

P.S. Keybindings in smplayer can be set through Preferences, and someone could actually put Ctrl+Q as the quit shortcut but I think that this should be the default setting like most other applications have it. Uniformity matters.

On my Macbook (4,1) I am currently using Debian with kernel 2.6.30-1-686-bigmem. This Macbook has Broadcom 4328 wireless chipset installed (02:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03)) and unfortunately the necessary kernel module provided by Broadcom is pretty unstable. Or very unstable. Oh well…it’s totally unstable.

I had random freezes, usually when I first booted and tried to modprobe the module. After some searching around the net and a lot of experiments I’ve managed to create a kernel module that looks quite stable. At least I stopped getting any more lockups and freezes…To reproduce the module with the patches I’ve used follow the directions bellow step by step.

Find your kernel version:
mybox:~# uname -r
2.6.30-1-686-bigmem

Install kernel header files related to the kernel version you found (on the above example it is: 2.6.30-1-686-bigmem):
mybox:~# aptitude install linux-headers-2.6.30-1-686-bigmem

Remember to replace the version (2.6.30-1-6-bigmem) with the output of your mybox:~# uname -r

Create necessary dirs:
mybox:~# mkdir hybrid_wl
mybox:~# cd hybrid_wl

Download Linux drivers package from Broadcom:
802.11 Linux STA 32-bit Driver
(Driver info site: 802.11 Linux STA driver)

The following configs can be used when you have either Vodafone Mobile Internet or Cosmote Internet on the Go or both 3G USB sticks and you want to connect to the 3G Internet (in Greece) while using Linux. I’ll provide two ways to connect to 3G, the command line way using wvdial and the GUI way using umtsmon.

1) Using wvdial
Create /etc/wvdial.conf:

[Dialer Defaults]
New PPPD = yes
Dial Command = ATDT
Dial Attempts = 1
Modem = /dev/ttyUSB0
Modem Type = Analog Modem
ISDN = 0
#commented out see the comments on the post.
#Baud = 460800
Username = user
Password = pass
Init1 = ATZ
Init2 = AT&F E1 V1 X1 &D2 &C1 S
[Dialer cosmote]
Phone = *99#
Stupid Mode = 1
Init3 = AT+CGDCONT=1,"IP","internet"
[Dialer vodafone]
Phone = *99#
Stupid Mode = 1
Init3 = AT+CGDCONT=1,"IP","internet"
[Dialer vfPIN]
Init4 = AT+CPIN=1234
[Dialer cmPIN]
Init4 = AT+CPIN=5678

WARNING: You HAVE to change the PINs on the last part of the config

To connect to Cosmote, plug in the usb stick:

# wvdial cmPIN
# wvdial cosmote

To connect to Vodafone, plug in the usb stick:

# wvdial vfPIN
# wvdial vodafone

2) Using umtsmon
Connection->Manage Profiles and create the necessary profiles with settings that look like these:

Username and Password does not really matter. Enter something like User/Pass or Username/Password.

Both versions tested on Debian and Gentoo and they are working just fine.

If someone has the Wind ADSM settings please provide them as a comment so I can complete the post with all three Greek 3G providers.

I am using the Password Exporter addon for Firefox to sync my passwords between my various Firefox installations (2 OS on the laptop, 2 OS on the desktop and one for portable firefox on a usb stick). I am using it with version 3.0.X and 3.5 just fine.

I have created a shell script that finds the differences between two exported password files and creates a new xml with the differences of the two so that one can edit it and pick the ones he wants imported.
File: ff-password-sync.sh
To use it follow these two steps on each firefox installation:
Firefox->Tools->Add-ons->Password Exporter->Preferences->Export Passwords
Then use the script (you need bash and mktemp):
$ ./ff-password-sync.sh laptop-password-export-2009-07-01 dektop-password-export-2009-07-02
If it runs successfully you should have 2 files in your home dir:
ff-password-sync.diff: Contains the differences of the two files in diff format
ff-password-sync.xml: Contains the unique username password combinations that are missing
Edit ff-password-sync.xml to possibly remove entries you don’t want imported and then go to:
Firefox->Tools->Add-ons->Password Exporter->Preferences->Import Passwords
and load ff-password-sync.xml

If you engage in this process it’s almost certain that you will hit this bug:
“Can’t add a login with both a httpRealm and formSubmitURL.’ when calling method: [nsILoginManager::addLogin]”

The fix is provided by a user on his blog: Fix for Firefox’s Password Exporter Add-on

I’ve uploaded an ebuild for the latest version of nicotine+ on gentoo’s bugzilla. Nicotine+ is a great p2p app written in PyGtK2 to connect to the Soulseek network.

I’ve also added psyco as a USE flag since it makes nicotine+ faster…but sadly, a bit more unstable as well. Test it and see if it makes any difference to you.

Ebuild: nicotine+-1.2.12.ebuild

I’ve decided to start a filter for adblock plus to filter out advertisements from Greek sites.

You can find more information on subscribing to the filter on the page: Greek adblock plus filter.

I started the list a long time ago with some personal filter for sites I visit the most. In order to enrich the list I searched and found a list with the supposedly “top 50” greek sites (regarding traffic), so I visited them and started adding filters to reduce the ads on them.

I warn you though, the filters are a bit strict…and I don’t like flash ads…I really don’t. I hope you like the list.

Please contact me, by email or by commenting on Greek adblock plus filter page to add your own custom filters to the list.

With the recent addition of halevt in Gentoo’s portage it is now relatively easy to automatically mount media like USB sticks and CD/DVD discs on /media.

What I wanted to do was to emulate my previous set of configs and scripts that ivman used to create icons of automatically mounted media on ROX desktop (called pinboard). I am using ROX pinboard on top of my favorite window manager, fluxbox.

The idea is that halevt is started by the fluxbox startup config file and when a new device is attached to the computer, halevt config calls a script that creates an icon on the ROX pinboard using ROX rpc. When a device needs to be removed ROX pinboard is configured to call a special eject command that checks for a couple of things before unmounting the device and calling the script to remove the icon from ROX pinboard.
Apart from automatically mounting/unmounting of devices I have also added a nice option in the halevt config to unmount and eject the CD/DVD drive when the eject button on the device is used and of course when the CD/DVD is not in use. That emulates a bit the windows behavior that so many users have gotten used to.

Since the script used by halevt involves a lot of file reading/writing and parsing I thought it would be wise to convert my old rox.panelput bash script to perl. And I was correct, the speed difference, even for such simple tasks is more than noticeable.

The installation process. Please take notice of the user executing the commands, $ is for normal user, # is for root:
0) create /usr/local/bin/ path and put it in your shell’s PATH
# mkdir /usr/local/bin
$ echo "export PATH=$PATH:/usr/local/bin/" >> ~/.bashrc

1) install halevt
# echo "sys-apps/halevt ~x86" >> /etc/portage/package.keywords
# emerge halevt

I’ve recently migrated on my debian from iceweasel (firefox) 3.0.X to swiftfox (firefox) 3.5b99 and I noticed that I could not import any new certificate authority root files. When I used a new profile everything worked as expected, so it was something that had to do with the migration of my old version 3.0.X profile to the new, version 3.5. It looks like there has been a modification in the way firefox 3.0.X and firefox 3.5 handles cert8.db file inside the profile directory. As soon as I deleted the file and restarted firefox I could import new certificate authority root files just fine. Of course I lost the old ones I had imported in the past…

I’ve bumped into an Iceweasel + adblock plus bug: iceweasel: AdBlock Plus (1.0.2) custom element hiding filters does not work
It looks like Iceweasel from the stable branch of debian (version 3.0.6-1) has a problem hiding elements from websites. That makes some parts of adblock plus useless and ads start appearing on various websites.
What’s weird is that the problem only appears on Iceweasel and not on official Firefox (as the bug report says).

My options were to either a) switch to a testing/unstable version of Iceweasel from debian, b) get a binary package from firefox website or c) get another custom version. I chose method c) and I got swiftfox. Since Swiftfox provides a nice debian repo it was really easy to install and test. The whole experiment got even more interesting since swiftfox provides builds for firefox version 3.5…

After a update-alternatives --config x-www-browser I was ready to test it.
Swiftfox 3.5b4 works great with adblock plus and it even feels a bit faster. I can’t really tell for sure though. The only addon I had to reinstall was firegpg.

My impressions are great so far and I think I will keep it, at least until the bug mentioned gets resolved somehow on the stable branch.

I’ve finally settled down to a solution that I am happy with. I used to have the following options inside my Xorg.conf:
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
[...snip...]
Option "TapButton1" "1"
Option "TapButton2" "3"
Option "TapButton3" "2"
Option "VertTwoFingerScroll" "1"
Option "HorizTwoFingerScroll" "1"
[...snip...]


This works like this:
i) a single tap is a left click
ii) a two-finger tap is a right click
iii) a three-finger tap is a middle click
and you could scroll horizontally and vertically using two fingers on the touchpad, like Mac OS X.
The problem with this setup is that I used to have a lot of accidental double tappings while scrolling with two fingers horizontally or vertically. This of course produced unwanted right clicks.

I wanted a solution that I could get right click in somehow like Mac OS X does it, using ctrl+tap/ctrl+click. I found a solution that emulated ctrl+click as a right click but then many applications started misbehaving. Firefox for example uses ctrl+click on Linux to open a link on a new tab, when I used ctrl+click as a right click, Firefox stopped opening the links. So I went to plan B.

CMD key(apple key)-click as a right click.

To achieve that:
a) install xvkbd.
Debian: apt-get install xvkbd
Gentoo: emerge xvkbd
b) install xbindkeys.
Debian: apt-get install xbindkeys
Gentoo: emerge xbindkeys
c) create the default .xbindkeysrc file: xbindkeys –defaults > ~/.xbindkeysrc
d) edit it and put the following inside: "xvkbd -text '\m3'"
mod4 + b:1 (mouse)
e) edit xorg.conf and set this: Option "TapButton2" "0"
This effectively disables double tapping as a right click.
f) restart X
g) open a terminal and start xbindkeys from it: $ xbindkeys -n -v
Now press CMD key and tap the touchpad or click the touchpad button. You should be greeted with a fresh right click!

If all went well put xbindkeys in your DE’s autostart.

The following works flawlessly on XFCE/LXDE. CMD-click or CMD-tap opens XFCE’s menu or LXDE’s desktop menu.

On fluxbox though there is still a problem. It’s very common for fluxbox key config to look something like the following:
OnDesktop Mouse1 :hideMenus
OnDesktop Mouse2 :workspaceMenu
OnDesktop Mouse3 :rootMenu
OnDesktop Mouse4 :nextWorkspace
OnDesktop Mouse5 :prevWorkspace


So to open the RootMenu, which is the basic menu with the applications shortcuts for fluxbox, one needs to actually right click on the Desktop. That worked with TabButton2=3 but it does not work right now. To get around that problem I binded the key left to (1/!) which is normally the (±/§) key on Macs to the Menu key using xmodmap.
$ cat .xmodmap
keycode 94 = Menu

I never used that key anyway…

I’ve now got my precious right click back without accidental miss-clicks. yihaa!

The output is also at: http://dpaste.com/52703/
Unless you are a Gentoo Developer there is no easy way to understand the output.
So I joined #gentoo-el on Freenode to ask the greek gentoo developers (hwoarang, deathwing00, tampakrap, wired, yngwin), which happen to be on QT/KDE herds, to explain to me what’s wrong.
I was suggested to run an emerge -uDavt world to upgrade my whole system, but that’s not what I wanted and I asked for a solution that would not involve upgrading the whole system. The following is the output of emerge -uDNavt world:

http://pastebin.com/m8371430

Then they explained to me that there has been a change on QT eclass to provide protection to the system from having mixed QT versions. The problem is that the protection works by blocking the mix, but the output is at least “unfriendly”.

The solution, as alex said is to do: emerge -av1 `eix -I --only-names x11-libs/qt-`

Even though eix is a standard tool every gentoo user has probably installed, I don’t really like the solution because it depends on using another extra program, eix, and not pure portage techniques. Portage should be able, somehow, to handle these dependency problems and provide a custom error when such a problem occurs. The errors on “-9999” versions need vast improvement.

I hope Gentoo devs do something about improving portage even more 🙂

*EDIT*
After a small conversation with alex, I completely unmerged my x11-libs/qt-4.X package. As it seems it’s not needed at all any longer since all programs correctly reference the x11-libs/qt-NAME-4.X.

Firefox has the feature of keeping links to downloaded files as urls using the file:// pattern. For example: file:///home/user/downloads/test.zip. If you choose ROX-Filer (/usr/bin/rox) to open these files you will get an error:

File doesn’t exist, or I can’t access it: file:///home/user/downloads/test.zip

One way to correct the error is to follow the instructions of http://lovingthepenguin.blogspot.com/2008/08/use-rox-filer-to-open-containing.html

Another way for Gentoo users, and much proper I guess, is to use /usr/bin/roxuri. roxuri is actually a shell script that uses the “-U” option for ROX:

-U, –url=URL open file or directory in URI form

For the non-Gentoo users, /usr/bin/roxuri is:
#!/bin/sh
exec "/usr/lib/rox/ROX-Filer/AppRun" -U "$@"

Create it and make it executable.

Go to Firefox Preferences/Applications/Content Type -> file and select /usr/bin/roxuri as the default application.

Now files from firefox downloads are handled correctly by rox which uses the proper applications to open them and containing folders open up with ROX-Filer. That means that while “file” is handled by roxuri, a .pdf will be opened by epdfview or whatever else you have chosen ROX to open pdf files with.

Both solutions work on ROX version 2.8.

Since yesterday halevt (HAL Events Manager) and its dependency, boolstuff library are in the official Gentoo portage!
halevt on Portage
boolstuff on Portage

They only thing it took was convincing hwoarang how much they were needed since ivman is pretty much borked. At first I asked him to add them to sunrise overlay but he insisted they go straight to portage.

The original ebuilds were taken from Gentoo bugzilla: new ebuilds for halevt and boolstuff -> supersedes ivman, they were refined a bit and then added to Portage. Thanks to Mike Gualtieri for the original ebuilds.

Hwoarang has added me as the proxy maintainer of these two packages. I hope that when updates go out, I’ll test them as soon as possible and then create new ebuilds for them.

The packages are currently only in ~x86 and ~amd64 (testing) branches. If you test the packages and think that they are stable enough please let me know and I’ll try to convince hwoarang to put them to x86 and amd64 (stable) branches.

Thanks again to hwoarang! Cheers!
