Weird mouse problem

Well, seems that I finally nailed it down. I changed the mouse from USB to the PS/2 port on my computer (using and adapter that comes with the mouse) and since then I' ve had no mouse problems. Maybe the fact that I was using two USB mice was affecting performance; I don' t know. At least the problem did go away. Thanks for all the help so far. By the way, Quentin, I' m running your kernel along with your version of jack, and it' s working wonderfully. Great performance in Ardour and Rosegarden. skullnotions: thanks for the useful info on the system logs and messages. I really learned something new during this process.

Maybe you could backup your xorg.conf and then compare\use the mouse settings from the 2.1 xorg. Checkout: graphics sound network various information post from this thread Use keywords (mice, usb) to grep dmesg, messages, and system info for errors. e.g. $ grep Mouse /var/log/Xorg.0.log $ dmesg |grep mice $ sudo grep mice /var/log/messages $ sudo grep Mouse /var/log/messages Cheers! Dave.

Well, I checked all of the above, installed the kernel from your repo, even disconnected all usb hubs form my computer, but still get the slow mouse problem. I'm out of ideas now.

Another thing: I have a PCI card that provides me with 4 extra USB ports. Could this be affecting the USB performance? Maybe I can remove the card and just use the USB ports of the computer. I had to add this card when I used Windows to record because of the USB keys required to run some programs (ProTools and Cubase, in my case), but since I'm not using them now, I can remove it and release some resources. I don't have any of the mice plugged to this card, but I remember that when I plugged a mouse to it, the mouse would work for a while and then stop working, as if communication with the device has been lost. I'll check this too.

It is on my personal repository for now, deb http://apt/harleystudio.co.za/ hardy main What kind of mouse do you use, and which apps are you running during the slowdown?

Update: Tried out kernel 2.6.26 but the issue is still there. In less than five minutes the weird mouse problem appeared again. So I'm back to step one. Were can I get the 2.6.29 rt11 kernel? What's the repo address?

The 2.6.26 kernel is a good one. It would have been the kernel for 3.0 if we did not run into some driver issues for newer systems. Do try the 2.6.29 rt11 kernel as well. There is a couple of extra enhancements I added for my system that you might want to try out. (64 bit) Next week I will start up my kernel quest again. I'll announce them here on the forums when I find a good one. Cheers, Quentin

Thanks for the reply Quentin. I don't have any on-board graphics on my system. I'm using a GeForce 7300 LE PCI-Express card. My system has 2GB of RAM. By the way, I run 64 Studio 2.1 on the same system and don't have problems. However, I recall that I installed AV Linux 2.0, which also uses a 2.6.29 kernel, and had the same problem. Could it be an issue with the 2.6.29 kernel? Maybe I should try another kernel to see how it behaves. I saw a 2.6.26 kernel on your repos and perhaps should give it a try. By the way, I believe there are other testing kernels. What's the repo address to get them?

Perhaps you need a treadmill for the mouse... and mice like corn much more than cheese. Jokes aside, It sounds like you might be using the on-motherboard graphics card, or running low on RAM. See, RT kernels use system resources differently, and if it wants access, it gets it - NOW. Non-essential stuff without RT access (like the mouse) gets shelved for a free cycle. The problem with on-motherboard graphics cards are that they generally share system RAM, making the memory bus a turbulent place, especially under RT conditions. After I added a very cheap GeForce 6200 graphics card, my system started to purr. No more erarric graphics, mouse slowdowns, strange x-runs. Hope it helps
