Unhappy Need help getting PCI-e 7800GT to work

Hi, I'm having a lot of problems getting my PCI-e 7800GT working under linux. I am using SimplyMEPIS 6.0 RC2. I tried installing the drivers (both the ones included with MEPIS, and the latest ones downloaded from nvidia), and they both have the same result. I can install them just fine, and the installation seems to go perfectly fine, but when I reboot the PC, right at the point where the Xwindows system is susposed to start, the monitor goes into power saving mode, as if the video card stops sending a signal to the monitor.

You can look at my original thread about this here:
http://www.mepislovers.org/modules/n...=16771&forum=9

And here is somebody who had the exact same problem as me:

However he solved his problem:

Wow, I took the xorg.conf file from the Ubuntu system, dropped it in the Mepis system and it worked like a charm. I think the big factor is that the Ubuntu system correctly identified the PCI Bus ID of my video card and wrote it to the xorg.conf file.

Anyway...this problem has been solved. Thanks for your help guys!!
But this would mean I would have to download ubuntu and install it just to get one file. I really don't want to do this, I don't have that much spare time. Is there any other way I can fix this problem?

I really need to get this working, please help me.

How would I generate that? And where would it be located? Remember, I can not use the KDE gui with the nvidia driver, otherwise the monitor dosn't work.

Ok, I did it. But keep in mind I did it using the vesa driver, because as I said, I can't do it with the nvidia driver because the monitor dosn't work with it.

I think it's a problem of mepis not detecting the proper pcie location of the video card, because the other guy that had this problem was able to fix it by copying the device section from the xorg.conf file from ubuntu. But this would require I download it and install it, wiping out my current settings, just to get one file.

Is there any thing I can do?

The bug report needs to be generated after starting X with the nvidia X driver. A bug report against the vesa driver doesn't tell me anything about the problem you're reporting.

Hmm, would it work if I install the driver, set the system to runlevel 3, log in and startx, then ctrl+alt+f1, and do the bug report from the command line?

Yes, that's fine, or just reboot to run level 3 after starting X.

Thanks,

Ok, I have made some progress. Bug report is attached.

I think I have found part of the problem, but I don't know how to fix it. I managed to take a look at the xorg.conf file before rebooting after installing the driver. Here is what it looks like:

Section "Device"

#BusID "PCI:1:0:0"
#Option "sw_cursor" # needed for some ati cards
#Option "hw_cursor"
#Option "NoAccel"
#Option "ShowCache"
#Option "ShadowFB"
#Option "UseFBDev"
#Option "Rotate"
#Option "NoUseBios"
#Option "BusType" "PCI"
Identifier "Card0"
Driver "nvidia"
BoardName "unknown"
EndSection

I think the BusID is wrong, I think the BusType is wrong (it's PCI Express), and I think the Identifier and BoardName are wrong. The exact video card is an eVGA 7800GT CO, and my motherboard is a DFI LanParty UT nF4 Ultra-D. The video card is in the PCIe slot number 1, for 16x. What should the correct values for these sections be?

Remove "IgnoreEDID" & "ConnectedMonitor" from your xorg.conf,and comment out all the Modelines.

If you're still having problems, generate a new bug report.

Thanks,

Oh my god!! Thank you!! It seems to be working perfectly now (at least the opengl screensavers)!!

Are these settings correct in the xorg.conf for best performance:

Section "Device"
Identifier "Card0"
Driver "nvidia"
BoardName "unknown"

#BusID "PCI:1:0:0"
#Option "sw_cursor" # needed for some ati cards
#Option "hw_cursor"
#Option "NoAccel"
#Option "ShowCache"
#Option "ShadowFB"
#Option "UseFBDev"
#Option "Rotate"
#Option "NoUseBios"
#Option "BusType" "PCI"

# savage special options, use with care
#Option "NoUseBios"
#Option "BusType" "PCI"
#Option "DmaMode" "None"

# nvidia special options, use with care
Option "CursorShadow" "1"
Option "CursorShadowAlpha" "63"
Option "CursorShadowYOffset" "2"
Option "CursorShadowXOffset" "4"
Option "FlatPanelProperties" "Scaling = native"
Option "NoLogo" "false"
EndSection

I'm going to try out UT2004 and Quake 3 now.
