GTK and KDE: unreadable fonts

I just found a note from several years back. Since it may someday be handy to someone, I'm posting it here:

KDE somewhat integrates GTK applications. These applications will get the color schemes from KDE. Sometimes fonts in menu's get rendered unreadable by this.

Wrong styles are defined in /opt/gnome/share/themes/Qt/gtk-2.0/gtkrc:

style "default"

{

  engine "qtengine"

  {

  }

}

class "GtkWidget" style "default"

Disabling this whole block fixed my problem.

Konsole is driving me crazy!

Konsole, the terminal emulator of KDE, is driving me crazy! Version 4.8 made a slight change, that breaks an essential feature I'm using.

Up to version 4.7.x, I used the command konsole --profile=Profilename to open a terminal. Then I used ctrl+alt+N to open several terminals with the same profile. For some reason, this broke in version 4.8. Since I use this feature like every minute, I'm getting very frustrated by this.

Here comes the beauty of open source: since Konsole is open source, I can fix it myself.

My changes

First, I downloaded the current version of the konsole source RPM and installed it, using rpm -i konsole-4.8.1-1.fc16.src.rpm. In ~/rpmbuild/SOURCES I created a new file named newtab.patch, containing:

--- konsole-4.8.1/src/MainWindow.cpp    2012-02-29 23:56:57.000000000 +0100
+++ konsole-4.8.1/src/MainWindow.cpp    2012-04-03 19:47:52.397594047 +0200
@@ -397,7 +397,8 @@
 
 void MainWindow::newTab()
 {
-    Profile::Ptr defaultProfile = SessionManager::instance()->defaultProfile();
+    Profile::Ptr defaultProfile = MainWindow::defaultProfile();
+              //SessionManager::instance()->defaultProfile();  //Geeklab fix
     emit newSessionRequest(defaultProfile , activeSessionDir() , _viewManager);
 }

Then I editted konsole.spec, adding a line after the one that starts with Patch50:

Patch99: newtab.patch

After that, I added a line after the one that starts with %patch50:

%patch99 -p1 -b .newtab

And we're done. Build the RPM using the command rpmbuild -ba konsole.spec --define "dist geeklab" and install it.

Somehow, this RPM doesn't cover all of the problems, but enough for me to be happy.

Konsole is hiding underscores

Today I upgraded my Fedora 15 installation to Fedora 16 with KDE 4.7.4. Although it was a pretty smooth transition this time, there were a few problems. One of them was that Konsole 4.7.4-2.fc16 was hiding underscores, which is pretty annoying when you're programming.

How the hell are you supposed to code when half of the characters is invisible?

I'm more than happy to report that I fixed it. On the profile's page "advanced" you find the option "Enable Bi-Directional text rendering". Enabling this option fixed the problem immediately.

Google'ing, I found a few pages that say this is specific to a combination of intel or nouveau driver + specific fonts + Qt 4.8.

Update: RedHat acknowledged the issue and released a fix: konsole 4.7.4-2.fc16. Update using yum update konsole
