Eratic behavour in the KDE desktop
 

I have Ubuntu Breezy and added KDE packages so I can work in KDE ( I'm a programmer using Qt3 & KDevelop3 ). I tried straight Kubuntu but had trouble mounting my thumb drives. Going this route solved the problem and the "System" on my KDE desktop now works.

My computer is a new Compaq ( amd cpu ) with XP Home edition. When I had several problems with Fedory Core 4, I tried Ubuntu/Kubuntu and really liked what I found!!

One of the problems I had with Fedora is still here in Ubuntu, a lot of jagged lines amoung other thing on the KDE Desktop. I have a 6 year old compaq with the same set up, but not the problem.

I went to the KDE forum and found a thread that had the same problem, added my problem to the thread. It will show some screen shots and a more detailed description of my problem

http://www.kde-forum.org/artikel/136...goes-wild.html

I hope I haven't commited a cardnal sin of coping someone else's thread from another forum, but I don't thing I was getting anywhere there.

Thanks

Does that happen with other desktop environments (e.g. GNOME) and window managers, or only with KDE? If it's not limited to KDE sessions only, then I suspect that it's a problem related to the video card and/or video driver. In that case, try posting at the nVidia Linux forum (read this first) or the Rage3D Linux Drivers forum (ATi).

Thanks Iron
It only happens in the KDE desktop, not gnome.usless I access somthing from KDE. My original instalation was Ubuntu and then I added the KDE packages..

It did not happen in 5.04. It also happened in Fedora Core 4 in the KDE desktop, but not with Fedara Core 3.so it must do with KDE 3.4.3.

I am running 1280x1024 on a Samsung 7i2N monitor. The vidio card is on the Motherboard.

II occures when KDE writes something to the screen, over writing anything on the screen. If I am in a program using the whole screen it doen"t happen. When it does happen and I click an "refresh desktop" it disapears.

I hope this is some help.

impeteperry, I was under the impression that Kubuntu is exactly the same as Ubuntu, except that it uses KDE rather than Gnome. Am I wrong about that? If that is the case, then why not just switch to Kubuntu if you like KDE? Are there other differences between the two that I don't know about?

No; Kubuntu uses KDE by default, but KDE can be installed on Ubuntu just fine, and it's mostly the same.

That would be pointless and most likely wouldn't resolve the issue in question.


impeteperry, you need to provide more details, such as:

• The brand and model of the onboard video (if you don't know, run lspci and look for "VGA compatible controller")
• The contents of /var/log/Xorg.0.log
• The contents of /etc/X11/xorg.conf
• The output of dpkg -l kdelibs4c2 libqt3-mt xserver-xorg-core

All of that will be rather lengthy, so try to paste it on e.g. pastebin.com and link to it. You can also reuse that should you decide to open a bug at bugs.kde.org.

Ubuntu & Kubuntu each install from their own CD (1 ea ). To do this they install with a different set of packages depending which "desktop" you want to use, but you can always add packages from the other system. In reality they are the same. I found the default Kubuntu packages had some hardware configueration problems that the default Ubuntu packages didn't and having never worked with gnome I did not know what ones I wanted to add to my Kubuntu. Going the other way, I knew what KDE packages I needed to add to the Ubuntu packages and I had everything I needed and it works great!

While I am on the subject, I go back to RH6.0, Storm 2000, Debian woodie, RH 7.3 and Fedora Core 1, 2, 3 & 4.
I am sold on Ubuntu/Kubuno. It is a debian based distro which I prefer to RPN and the 6 month upgrade cycle is just about right.

The "ispck" or "is pci" didn't yield anything.
I have the other info pasted as you instructed, but I not sure I know how to link it.

I had problems that looked like this. I thought it was due to the NVidia GeForce 6600 video card I have. I tried installing the NVidia drivers, but got nothing but complaints about kernel headers. After struggling for several weeks I started playing with the video settings. I reduced the color depth from 24 to 16 bits and it hasn't happened since. Not a solution, but a work-around. I can't tell the difference on my 19" lcd. For the time being, this works for me.

Thanks for the reply
I am not sure about changing the "color depth" as changing resolution in Linux doesn't have a place as windows does. I have attached part of /etc/X11/ xorg.conf which is where I think you do it.
I have changed the screen resolution to 1024x768 - get the same problem
I have changed the refresh rate from 75 to 60 - get the same problem.
I have changed the display defaultDepth from 24 to 16 in the "quote" above - get the same problem

Actually, I have this problem under Mandriva 10.2 (2005LE). I followed a link from another thread to get here. I changed the default color depth using the Mandrake Control Center. I'm not used to dealing with the Xorg conf file, so I can't be of much help. All I know is changing the other settings didn't change the bad behavior on my machine. It's possible the problem on my machine is not solved and the display will go crazy any moment.

Thanks Jim.
I'm running Ubuntu, but had the same problem with Fedora 4.
I tried adding an ATI Rage Pro card I had, but Windows XP would not accept it and my Linux just went blank. A man at a computer store suggesed downloading a current driver for the card, which, I have done. Tomorrow I will try again with the new driver. Will post the results here

I tried to install my ATI card, Either i don't knvow how to do it or XP wouldn't let me. I downloaded an uptodate ATI-XP driver for the card, but never got around to using it. Back tht the screwed up desktop ""/?*g\}*#$"

Somemore information on this problem.

If I don't use "full screeen" when I'm programming but leave a small band of the desktop showing at the right edge of the screen, when the lines and other stuff show up, I right click on this strip of desktop and then clrck on "refresh desktop" once or twice, the bad stuff is gone.

Sombody in this great world of ours must have some idea on what is causing this or tell me how I can install a different video card. I have not done this when the existing video card is on the mother board. ( SIS S17012 ). I am running XP home edition and System Commander for my dual boot.

Thanks.

that would be Lspci.

Thanks. Looked at the site. It will take some time for me to digestt it. Will respond when i get somthing
