1 minute ago, when messing with kernels and nVidia drivers I get 260.19 drivers running in the desktop kernel, I will hibernate that session for as long as it continue to work. But the problem persists. Below, the bugs.
I’m experiencing an annoying double bug killer combo.
- OpenSuse 11.3 (kernel 126.96.36.199-0.4, both desktop and default)
- Xorg 7.5 (I think, the one which comes with the distro)
- nVidia binary 173.14.28 (nVidia GFX-01 package)
In an Acer 5520G wich comes with:
- AMD Turion X2 TL-58 (1.9Ghz.)
- 2GB RAM DDR2 800
- nVidia 8400M
- Atheros 5001-like wi-fi
Xorg decided to take down my CPU, so it uses ridiculous amounts of CPU time for no known reason. I do the following:
- Log in session*]Open System Monitor to see what happens*]Xorg uses about 2% CPU (nice)]Move Mouse -> Xorg CPU usage rise up to 41% (alarms go off)]Stop moving mouse, try with touchpad -> Xorg does the same*]Start using the computer as usual (mail + documents + broswser) -> Xorg CPU usage doesn’t go lower than 35%, peaks about 55%*]Open 2 browsers (Opera and Firefox, for the record) -> Xorg uses as much as 95% CPU
This makes the CPU to overheat considerably (~85-90°C).
There is a bug in the wireless driver which makes it to somewhat disable the wifi card if the computer overheats too long (more than 1 minute).
So, after using the computer, lets say, 5 minutes or even less, it overheats and I loose wifi connectivity.
OpenSuse still thinks the wifi card is up and running and tries to reconnect without luck. The only ways to recover conectivity are: complete shutdown of the computer or sleep-wakeup.
I’ll loose connectivity as many times a day as I let the computer overheats, and that will happen as many times as I forgot to turn on powersave mode and Xorg will eat my processor until it overheats, which happens very quickly.
As you may imagine this is a real annoying killer combo, because since Xorg eats as many CPU as it can, the computer runs pretty slow, and in powersave mode (processor goes down to 800Mhz.) it’s almost impossible to use.
This didn’t happen in such a bad way (but it happened nonetheless) nVidia 256.XX drivers. With newer 260.19 drivers plasma crashes miserably after logging in and computer is unsuitable for work (as you already guessed).
My problem is to solve this two bugs: Xorg excessive CPU usage and wifi disabling when computer overheats. Also, making nVidia 260.19 drivers to work will be great.
I already tried several things, including recently killing Xorg when installed some version from Xorg repository replacing opensuse default version. It was a little headache to roll back and making Xorg up and running again.
Anyway, I’m open to suggestions, I’ll try everything I can manage to understand I will provide more information if required, but since I don’t have much free time, don’t expect answers too soon.
Thanks in advance,
ps: with plasma-desktop dead and nVidia 260.19 drivers, Xorg behaves more nicely, not surpassing 11% which is quiet better than 95%.
