Thinkpads Forum

I have installed ubuntu on my t22 for about... 4 months. I am getting used to the os.

A while back I recompiled my kernel to enable super low latency audio interfacing... this in turn made the few games I am able to run using wine crap out, and now I am distressed.

So I followed the instructions to delete those kernels and boot from my old kernel. This all went well. Now everything seems to be working alright... BUT my cpu seems to be running very hard, and my memory is being swamped quite often. As for the games Baldur's Gate run's fine exept for a lag that hits about every 4-5 seconds like it is catching back up to itself. it makes it impossible to play.

I am not really sure why I am telling you all this here-- I am going to go talk to the forum that had me rebuild the kernel anyway, but I was wondering if you guys had any suggestions or knew of any compatibility issues with a t22 and ubuntu.

also, my writer is kind of being dumb, and everyonce in a while I will try and open a .doc saved in writer and open it in microsoft word and it gives me jumbles.

and I guess one more thing. Using mplayer to play a dvd craps out almost every time. plus the audio is so latent you can't even watch it.

I am suspecting some video/audio card clashes with ubuntu.

If the CPU is pegging at high utilization all the time, try tracking down whats causing this as it might be the root cause so it might be worh spending maybe a couple of hours inverstigating this before doing a re-install/kernel buid. At a prompt / konsole, type

nice top

watch for CPU utilization percentage to see which process is the processor hog. Firefox with multiple tabs in notorious for eating up huge chunks of memory and CPU.

To the OP:

When you re-loaded the original kernel, was it from the install media or did you do a re-compile? Also as suggested I would figure out which process it taking up all your CPU. You can renice it to use a lower CPU priority or you can to my favorite thing when I am the controller of the process:

1. Top (then find out which PID is using the most CPU)
2. sudo kill -9 PID (where PID is the PID you got from TOP)
3. Move on with your life.

If possible (I can do it on OS X) I would clear out your swap file. Also on re-boot boot into run level 3 (single user). Then frun fsck -y until it reports all is good. Some distros will run fsck for you when you boot, but it never hurts.

Other than that, I gave up on getting a stable install of Ubuntu on my T23. It's the reason I went back to SuSE on my T23. My Athlon64 tower runs kubuntu great.

------------------------------

I wanted to thank the above user for "nice top". Works much better than top alone.

the process is perl

I cannot kill it, because it says i have entered the wrong password, (even though I am never pw prompted)

but I can stop it.

that makes my game play run normally, however other applications get fussy and almost freeze
