Greetings, |

I have been trying to fix a somewhat puzzling and annoying problem over the |
4 |
last couple of months that has me absolutely stumped. I have been unable to |
5 |
isolate the cause of the problem and it appears to be intermittant at best. |
6 |
The issue rears its ugly head as follows: |
7 |
|
8 |
This is on a dual boot workstation with a Supermicro X6DAL-XTG motherboard, |
9 |
dual 3.0GHz Xeon processors and a GeForce 6600GT video card. The system has |
10 |
worked splendidly since I purchased it back in June with one exception: |
11 |
occasionally when rebooting the system to return to Linux from Windows the |
12 |
2D performance in Gnome is terrible. The problem does not appear immediately |
13 |
nor does it happen every time. Initially gdmgreeter appears as it should and |
14 |
I enter my login credentials. The Gnome desktop loads quickly and as I start |
15 |
to work applications load normally. However, after about 10 minutes the |
16 |
system load on one processor sharply increases to 100% when performing a |
17 |
simple task such as clicking on a button in Firefox, launching a new |
18 |
gnome-terminal window or clicking on the "Applications" menu at the top of |
19 |
the screen. The response time between clicking and the menu appearing for |
20 |
instance is anywhere from 2-5 seconds. There does not seem to be any quick |
21 |
fix for this which is what has me puzzled. If I close all of my |
22 |
applications, log out and log back in the problem "resets." Rebooting the |
23 |
system proves ineffective as well. I have tried various driver revisions, |
24 |
currently using 1.0.6629-r4, and several different kernels to no avail. I |
25 |
have tried both enabling and disabling the RenderAccel option in |
26 |
/etc/X11/xorg.conf and that does not appear to make any difference. |
27 |
Adjusting the NvAGP option does nothing nor does enabling the Composite |
28 |
option however the system seems more responsive when the Composite option is |
29 |
enabled. Switching to the "nv" driver resolves the problem and the system |
30 |
remains snappy with no immediate problems. Occasionally I will begin to get |
31 |
artifacts on the display with the nv driver and then the screen goes |
32 |
entirely white but switching to the console using ctrl + alt + F1 usually |
33 |
resolves this problem. I would appreciate any insight anyone could provide |
34 |
as to what I am overlooking. I have walked through the Gentoo Nvidia |
35 |
documentation numerous times and I have consulted the README document |
36 |
included with the nvidia driver. I am completely stumped. |
37 |
|
38 |
Currently I am using 2.6.9-gentoo-r9 for a kernel with the |
39 |
1.0.6629-r4version of the nvidia driver. As I said before I have tried |
40 |
several kernel |
41 |
and driver revisions to no avail. As a sidebar, 3D performance seems to be |
42 |
as it should be which puzzles me further. Again, I appreciate any advice |
43 |
anyone may offer. |
