Here's an Xorg problem (I think) that's bugging me. I've searched the forum and googled but don't find any answers.
I'm running Easter RC on two PC's here - AMD XP1500 and P4 1700. Both have Nvidia Geforce2 and 768M ram. During August I d-u both PC (using h2 script so I get it right) and now I experience times when the machines run very slowly. For about 5 seconds the mouse pointer moves with difficulty and everything runs like it's covered in glue, then it's ok again. This may happen several times in a minute, or not at all for a few minutes. I can sometimes trigger it by running Firefox/Konqueror (and nothing else) and doing normal browsing things like click on links and moving the window
My impression is that everything was ok until Xorg7, but I'm not 100% sure of that. There was no problem with Easter-RC out-of-the-box
I use the nv driver, not the nVidia binary
Here's some meaurements I've made on Xorg's cpu usage with top running at 0.5 second update on a quiet system with a single Firefox (or Konqueror) window:
Idle 2 - 5%
Grab window and move it around 30 - 35%
View web page with animated gif 70 - 75%
Under these conditions the PC response is fine
When it's in slow time 95 - 97%
Any ideas for the cause/fix, or any more data I can gather, would be appreciated.

| Just wondering ... why don't you use the nvidia drivers? |

| not everyone wants to taint their kernel with proprietary modules- and for normal desktop usage, whats the point? |

h2 - thanks, I checked and the gtk2-engines-gtk-qt package isn't installed according to synaptic
As far as the nvidia drivers are concerned, I just got out of the habit after a bad trip with them (instability) a couple of years ago. I'm sure they're ok now, but I don't play games or do heavy rendering graphics so I've not seen the need. Mind you the animated gif load figure was a surprise to me too. Perhaps I'll do a quick partimage and try them to see if it makes any difference

Try the nvidia drivers, they have been pretty solid for a while now.
Otherwise, this question comes up now and then, and pretty much every time it turns out that the person who's system slowed down did something or other that caused it, usually adding some program, compiled, that they shouldn't have.
Also make sure that your current partition isn't full, use: df -h
command in console to check that. And watch your ram/cpu useage some more, htop gives pretty accurate results.
The animated gif seems to be very resource intensive, even when there is no problem in the system. That's always noticeable, but your numbers seem too high for that. |
