Pointer Trails on Desktop and Open Programs

[Art McClure]

I looked at most of the FAQ's and a number of forums, but could not find anything relevant to my problem. Using a PS/2 mouse, but I get pointer/cursor trails on the desktop and on open program windows. They go away if I refresh the desktop, but in open windows they may go away if I open a menu item, then again they may not. In OO the cursor leaves "black" marks all over the page, especially if I try to do any editing. If I open a menu item (such as <Edit-Select All>), the little black boxes disappear, most of the time. Other than that, Knoppix from the CD works great on my system, having configured, sound, video, network, etc. settings correctly. Any help would be greatly appreciated.

Art,

Unless you have "mouse trails" enabled, I think Knoppis has this, just like Windows, which, from your description, this is NOT mouse trails...

I think it may have something to do with your system.

I used to get "ghost" window screens, when I moved them around the screen, to fast - the system would "catch up" eventually, and the previous image would disapear, but it was a pain.

In my case, the processor wasn't the slow part (I have a 1.7 GHz AMD), the hard drive was a new "high RPM", so that wasn't the cause, it was my video. Having a "motherboard" mounted, shared memory, video card - was the slow down on my system...

Once I installed a "full-blown" video "card" - with its own processor, and its own memory, the problems went away...

Not having, or been given, any information on your system, I would guess this to be your problem...

You might be able to help, myself and others, out finding more answers, if you would post some system information:

(1) Knoppix (version, and if it is running on the CD or installed on your hard drive)
(2) CPU (speed, and type)
(3) Memory (amount)
(4) Video (is it on the motherboard, or seperate card, does it, and how much, memory does it have)

I don't want to "suggest" that you purchase a video card to resolve your problem, unless, I can be sure that "it would" fix the problem - not having any information, I "wouldn't" do that, maybe others can help even more, if more information is given about your system. This problem could be a "combination" of things, video + processor, video + memory, video + hard drive swap, etc... and it could be something by itself, video, swap, memory, processor, etc...

Not having more information (specific) to your system, diagnosis is like trying to find a needle in a haystack.

You may want to include an output of your "dmesg" - this is the stuff that "scrolls" down your screen when you boot. To do this: on the icons across the bottom of your Knoppix, look for the icon that looks like a monitor that has a shell in front of it - it should open up a "Konsole" window. When the window opens, it should have a "prompt" where you can type commands after it. Type the following:

dmesg

Scroll back through the output and select the text, copy, and paste it into a reply post here. This information can provide insight into what "Knoppix" installed, devices it found, services that were started, and any problems it may have had, during the boot. You can also look through the output of this, and see if you can pick out information that pertains to any of the questions above, and post "snippets" of that output as well.

Info Center is another "nice" program to "view" things with - unfortunately, the information found in this program, is not able to be "copy / pasted" - but does provide a easy way to view information about the system. You can find it by clicking the "KMenu" icon - usually the first icon from the left, at the bottom of the screen, go up to "System", and the selections that pop out from that menu, you should find "Info Center". This program can view memory, devices, disk usage, etc... The "PCI" section may display information about your motherboard, video, sound, usb, and IDE devices.

Hopefully, with more information, your issue may, or can, be resolved - or at least know what is the cause.

Hope this helps,
Cuddles

Thanks for the reply.
I am using Knoppix 3.3 from the CD. I tried the disc in another computer, it runs without flaw (well almost). My bad computer is:

Athlon XP1600 with 512MB RAM
MSI K7T Mobo
Intel i740 video card with 8MB RAM

I never considered the Intel card to be a "real" display adapter, it had many problems in Windows until Intel upgraded the drivers.
Let me explain the exact problem that I am having. When I click on a drop-down menu, then click on an action, the menu disappears as it should, leaving behind a small "block" that shows a view of a section of the old drop-down menu. Sort of a little window to what used to be there. In OO, if I try to select text with the cursor, it rarely works, and if it does it selects part of the text or the wrong selection of words. For example, if I select a line of 10 words, maybe none will be "painted black", or sometimes just the first word and the last word. Using <Edit, Select All> works as it should.
Sometimes the cursor can't select any text at all. If I move the cursor on the screen while waiting for a program to complete an action, it will leave a trail of little boxes that may disappear when the action is completed.

Below is my demsg listing:

I appreciate any help in this matter, as I would like to install Knoppix permanently on my computer.

[Cuddles]

Art,

I think we have the same motherboard video here...

From your posted dmesg output:

Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected Via Apollo Pro KT133 chipset
agpgart: AGP aperture is 64M @ 0xd0000000

Knoppix, as with my install, above states it has detected a Via Apollo Pro KT133 -=- I have the "exact" same motherboard mounted video card - it was "also" the same card that had problems on my system. If this is true, the memory you are reporting for your video memory, is in fact, your main system memory "shared" to the video card. This was also the problem with my video woes...

I did not see anywhere within your dmesg output that "another" video is being introduced, so my thinking is that your video card "is" on the motherboard, "is" using your system memory shared to your video card (which is very slow compared to video RAM), and thus, my conclusion is - your video card is having a hard time dealing with Knoppix and its refreshing needs.

I can attest that I had Win98, before I "jumped" "whole-hog" into Knoppix and GNU/Linux - and with Win98, I never had a problem with video related problems. When I introduced my system to Knoppix, my video began to have problems. This could be from many things. I never ran Windows above 1024 x 768 16 bit resolution, whereas, my Knoppix is now running one setting above that resolution. Your dmesg output appears to be using the 1024 x 768 x 16 bit. Your processor is fine, mine is close to yours. Only thing I can think of is the video, and the shared system memory.

Before I got another video card, other than the KT133 on the motherboard, I would get "pointers" stuck on my screen, until I "hovered" over a menu item, and then the pointer would vanish. With the new video card, nothing, so I can conclude my problems were associated with the motherboard mounted video card. You may be able to try another video card, any kind, that can be inserted into the system, and then boot up with the CD. I went out and bought a "cool" GeForce4 - but I wanted to "upgrade". For testing purposes, any video card that is not mounted on your motherboard could be a test with.

Maybe someone else has more "background" on this issue than I do, I hope this, kind of, helps...

Thanks for your interest!
My Mobo does not have built-in video. However, this i740 is a certified piece of ca-ca. When I opened the box that it came in, there were paint brushes and three containers of paint. I have a GeForce MX 440 that I am going to install. Knoppix works absolutely great on my newer computer, so I am going to keep trying. Today I decided to buy a new computer so that Knoppix will be all alone and no dual booting. Barton 2500, Shuttle AN35N Ultra w/ 256 DDR PC2700 RAM. I just need Open Office to work as it should.
Thanks for your time and concern. Personae like yourself make forums worthwhile.
