Either AGP or standby modus with Nvidia?

Vagabund · 11-25-06, 02:34 AM

Hi everybody,

i have a small problem with my system. If i use the standby-modus with Fedora Core 6 (and all other distributions) and restart the system i have always a black screen. Only a reset helps. I have read in this forum i can use the follow option in the xorg.conf:

Code:

Option	    "NvAGP" "1"
Option	    "VBERestore" "True"

Ok, this helps. I can now use the standby-modus. But this option deacitvates the AGP-modus. I think with this option the complete system feels slower (with compiz). The follow commands says:

Code:

$ cat /proc/driver/nvidia/agp/card
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x 
Registers:       0xff000e1b:0x00000000

$ cat /proc/driver/nvidia/agp/status
Status:          Disabled

$ dmesg | grep agp
Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected an Intel i875 Chipset.
agpgart: AGP aperture is 128M @ 0xd0000000

Glxgears says with AGP 3800 FPS and 3400 FPS without. Can anybody help to solve the problem? Thanks in advance.

Regards
Michael

Read appendix Q of the driver readme for more information. There are some known issues regarding standby and it doesn't work that well for most people.

In the past, a number of Linux AGPGART backend drivers also didn't implement power management functionality (or didn't implement it correctly); judging from your experience, this may still be the case. You may want to try the builtin NvAGP AGP GART driver, instead (see http://download.nvidia.com/XFree86/L...ppendix-q.html, as Thunderbird suggested).

Thanks for your help, but i have found a solution in the german fedorawiki
http://fedorawiki.de/index.php/Suspe...Nvidia-Treiber
- No changing in the xorg.conf
- grub.conf added with agp=off
- etc/pm/functions-nvidia /usr/sbin/vbetool post removed
Now AGP8x with suspend standby/hibernate works perfect.

@Vagabund: it sounds like you switched to the builtin NvAGP AGP GART driver, as suggested in the README (agp=off disables the Linux AGPGART driver).
