Hi.

I've installed Debian 3.0 Woody on my laptop. The laptop is a Dell Latitude C600. When in KDE, I use the touch pad - ain't got no mouse...

The problem is that the cursor freezes at what appears to be arbitrary intervals for about a minute (and longer) at a time. After a while it is ok again for a couple of minutes before it freezes again. While the cursor is frozen, I can still navigate freely with tab, arrow keys, type in xterm or an editor. It's just the mouse cursor that won't budge.

I previously had Suse 7.3 installed and that did not give me any hassles of this kind.

Has anybody had a similar experience (and solved it? Could somebody point me in the direction of a solution, please?

Thanks
Joe

I've had no luck using the touchpad on a winbook xl and have posted a bug with redhat. it works great with 6.2 without the updated kernel-pcmcia-cs. update the module or try to install 7.2 or 7.3 and the mouse / keyboard lock up. >https://bugzilla.redhat.com/bugzilla...g.cgi?id=70999 In my experience, this sounds like an irq conflict. some touchpads use psaux which generally like irq 12. the pcmcia controller also likes this irq and, unlike some resources, they don't seem to coexist very well (due to latency issues?). To check this out, you could:

1. list your modules.
lsmod
2. list your pci resources
lspci
3. list your irq interrupts
cat /proc/interrupts

and post the results back here. someone who knows what they are talking about may be more helpfult than me. if the output from these commands doesn't seem helpful, you could:

1. list how your hardware is being interpreted by the kernel
dmesg

Thanks for the response. Here's the output from the various items you listed:

Sorry that it doesn't look too well formatted - dunno ho wto change the font...

Thanks for any and all help.

Well, I don't see an obvious answer here. I checked out your Dell on the Linux for Laptops page
http://www.linux-laptop.net/

I don't see any similar problems reported there (and now would be a great time for the moderator to come to my rescue). it's also possible that your problem is related to your debian distro or at least your debian distro with the latest iteration of the kernel. i found a discussion of a similar problem on the debian discussion board from yesterday. If that's the case, you might want check out the solution suggested there and do a posting there if you need more help.

http://www.geocrawler.com/lists/3/De...201/0/9828984/

However, if you want to continue to work this as a possible resource conflict, I'll continue on from here.

First dmesg, I don't see any errors here related to your problem. There is the error message at the end complaining about AGPGART but this should NOT relate to your mouse problem because this module handles agp hardware access for your video card.

lismod shows that both your xircom (pcmcia combo NIC/modem) and your pcmcia controller are loaded (line 3, tulip driver for the xircom and line 16, i82365 (driver for the Intel i82365sl PCMCIA host controller). Your PCMCIA controller politely took IRQ 11 so your mouse is sitting nicely at 12.
The only question I see relating to a possible resource conflict is that your xircom card is not reporting an IRQ under cat /proc/interrupts. i'm not at a linux box right now but I think that

ifconfig -a

should list your nic card with its interrupt assignment. check it out, if this is the problem we can just reassign your nic to a safe irq.

Thanks for all the effort, it is much appreciated.

I ran ifconfig -a as you suggested and the output for eth0 reports the interrupt as 11. Is that a problem?

Something else that I've noticed, is that the pad "unfreezes" when I start up a program (any program) while it is frozen. For instance, I press ALT-F1, scroll to games (or whatever), select an application, hit enter and the cursor can be moved again - for a while...

I will also post on the board you suggested.

Cheers
Joe

'nother question... I went to the geocrawler address you posted above, but couldn't find any way to subscribe to any of the lists. How does one post on those lists?

Ta
Joe

no. irq 11 doesn't relate to your mouse or keyboard. i'm out of ideas (that didn't take long).

regarding geocrawler, i'm not sure but i think that is a searchable archive of the mailing list.

regarding subscription information, try

http://www.debian.org/MailingLists/

An unsatisfactory conclusion...

I decided to reinstall Suse. Did so. Couldn't boot Win2K - which ordinarily isn't a bad thing, but this IS my work laptop... Fixed the Win-boot problem and reinstalled Debian, this time with the bf24 flavour. And, wadda ya know, the frozen touchpad is a thing of the past.

So the problem is solved, but I don't know how or why... I feel like a Windows-user

Excuse me, Mr. Joe Soap,
I have a Xircom CBE2-100 Cardbus Ethernet Adapter. I've been trying for so long to get this working with Linux.
(Actually this is the second card I tried, the first time I had an SMC8036TX Cardbus, and I wasn't successful)
I noticed you have a Xircom Cardbus Adapter. I was wondering if you can guide me in installing this Ethernet Adapter. Right now I have Mandrake 9.0 installed.

Hi dreville

Sorry mate. I haven't been able to connect to the internet via the laptop yet. Tried a couple of times with no success whatsoever. If you do find out how, please let me know too.

Good luck
Joe
