Some apps slow to start in KDE


I am wondering if anyone else is experiencing this. Some apps are slow to start up in KDE. The one that I notice the most is Konsole.

What I find interesting is, before I installed the nVidia driver and set my resolution when installing 12.2, Konsole opened right up. After installing the nVidia driver and setting the resolution to 1920x1200 (wuxga) there is a delay of a few seconds before Konsole opens up. XTerm opens up instantly.

I wonder if this is a side effect of KDEs scaling of fonts and my high resolution monitor. Konsole opens up much larger than XTerm.

I noticed the slowness in opening apps on 12.1 also.

I use Slackware 12.2, KDE 3.5.10, and the proprietary nvidia drivers. I never have seen this problem here.

A common KDE test:

1. Exit X/KDE.
2. Delete all files and directories in ~/.kde/cache-hostname.
3. Delete all files and directories in ~/.kde/socket-hostname.
4. Delete all files and directories in ~/.kde/tmp-hostname.
5. Run startx.
6. Test for the same problems.

Another typical KDE test:

1. Exit X/KDE.
2. Temporarily rename/move ~/.kde to ~/.kde-old
3. Run startx.
4. Test for the same problems.

This will cause KDE to create a new ~/.kde directory and configuration files.

If the problem disappears then there is a configuration problem within the original ~/.kde files. If not, then the problem lies outside of KDE.

Thanks Woodsman.

It turns out that I wasn't using Konsole, I was using 'X Terminal Emulator'. It is strange that 'X Terminal Emulator' is the default in the KDE menu and not Konsole. I just assumed when I selected the terminal app I was using Konsole.

Anyway, 'X Terminal Emulator' is the problem. When ever I start it up or cause the window to redraw or pretty much any action other than typing in the terminal, it causes my whole system to freeze for a few seconds. So the solution is simple, swap Terminal for Konsole on the menu.

Great, thanks again.

Hmm. I use KDE 3.5.10 and have used KDE for years. Konsole has always been the default terminal window.

What is X Terminal Emulator? You separately mentioned xterm and Konsole. I presume those apps are not what you meant by X Terminal Emulator. From where did this app get installed? Do you mean the Xfce Terminal or something else?

Easy part: If you want Konsole to be the default terminal, then learn why that got changed. Start with the Control Center: Component Chooser, Terminal Emulator.

I find handy to add the Terminal Sessions applet to my Panel Task Bar. Moreso, I assigned a keyboard shortcut (Alt-F9) to my Konsole terminal. I also assigned Alt-F10 to open the Konqueror file manager profile. No reaching for the mouse.

Konsole is set as my default in the component chooser.

What happened was, in KDE I have been going to the utilities menu to find the terminal and there is only one listed there. The one in the utilities menu list is the xfce terminal. If you bring up the help in the xfce terminal, all it says is "Terminal 0.2.8.3. X Terminal Emulator". I didn't know it was xfce until just now when I followed the link in their help.

Strange... And I have been doing this through 4 or 5 installs of Slackware, always thinking the slowness was due to something I did wrong. Prior to 12.2 Slackware had a pre-3.0 Firefox which was just slow anyway. 9 times out of 10 I was using the terminal or firefox so I just assumed the whole thing was slow due to something I was doing wrong when it was just these two applications. (So I guess it was due to something I was doing wrong, but it was not a configuration thing.)

Oh, and I wanted to say thanks. I just saw your multimedia post and followed the link and see that you own the humanreadable site. That site has been a great help to me. I was just referencing the font info the other day.

From the CHANGES_AND_HINTS.TXT file:

Quote:
If you notice Xfce's Terminal and perhaps some other applications being drawn
very slowly in X, then you should try explicitly disabling the Composite
extension in /etc/X11/xorg.conf, or set XLIB_SKIP_ARGB_VISUALS=1 in your
environment prior to starting X. For more information on this, see:
http://bugzilla.xfce.org/show_bug.cgi?id=2792
Disabling the Composite extension in X has solved this problem with XFCE's terminal for me.

Okay, that clarifies that mystery.

Now, why is Konsole missing from your Utilities menu? Well, because that is not the usual location for the Konsole menu item. Look in the System menu. Don't ask me why developers can't be on the same page.
