 |
|
After emerging X, I configured XF86Config exactly as specified in the Desktop Configuration Guide. X runs fine with the nv driver, but when I try to run it with nvidia set as the driver, it won't start at all, and I get this error:
| Code: | (EE) No devices detected.
Fatal server error:
no screens found
|
I also have the log file that X generated. It's kind of long, but I'll post it if this isn't enough information. |

Did you uncomment (delete the #) the Load glx line at the start?

I have found that this usually means the nvidia module is not loaded.
What does | Code: | | lsmod | grep nvidia |
show?
If nvidia module is not listed then
Were there any errors in the ebuild of nvidia-glx or nvidia-kernel? |

I know that nvidia-kernel and glx both installed properly as I saw no errors from them, and doing lsmod shows that the module is loaded (although unused).
Looking into the log file that X generated when it crashed produces these relevant results:
Before it began probing anything PCI, it says:
| Code: | (WW) Open APM failed (/dev/apm_bios) (No such file or directory)
|
Then, further down:
| Code: |
(--) PCI:*(1:5:0) nVidia Corporation NV17 [GeForce4 MX 440] rev 163]... |
Now, close to the bottom:
| Code: | | (EE) No devices detected |

I think I may know what the problem is, although I'm not sure how to fix it.
In the log file, it shows all the drivers and corresponding functional chipsets that they use. Well, in my log file, it finds the nv driver and that the GeForce4 MX 440 chipset is applicable to this driver. But, no where in the log file does it show the nvidia driver, so no chipsets could be found to match it.
I gathered from looking at the log file from when X started up using the nv driver, as right when I get the message that device couldn't be found when trying to use nvidia driver, X finds my chipset and proceeds.
Anyone know of any relevant hacks to fix this ? |

Hm, I think the nvidia-kernel emerge needs a valid symlink in /usr/src/. This symlink is called "linux" and points to the current kernel (e.g. /usr/src/linux -> /usr/src/linux-2.4.21/).
So make sure this symlink is ok and then emerge the nvidia-kernel stuff again.
Also, try starting X with these options, they give more detailed logs: "startx -- -logverbose 5 -verbose 5" (logfile is somewhere under "/var/log/X.../")
