 Posted: Wed Sep 29, 2004 7:58 pm Post subject: Can't start X [SOLVED] |
 |
|
I've been following this topic to get a copy of an XFree86.conf file that should work with my laptop, but I get a "screen not found" error. The specs match pretty much exactly, except for the CPU. It was a copy-and-paste job through SSH to transfer the config from that topic to my laptop.
Here's what I get from the log:
(II) Primary Device is: PCI 01:00:0
(EE) No devices detected.
Fatal server error:
no screens found
I'm not sure where to go from here... For god's sake, it's the exact same hardware!
Also of note: I recently switched over from Mandrake, and under Mandrake I used that exact same config (I looked here for answers). It worked there. Something's obviously not configured correctly, but I'm not sure where. I emerged the nvidia-kernel module, added it to modules.autoload.d/kernel-2.6, and it even shows up under "lsmod" (in fact, it's the only module I have loaded). What else can I look for?

Do you have the nvidia drivers installed? What happens when you type "modprobe nvidia"?
I had a problem like that, in that X suddenly stopped finding usable devices, and it started working again when I manually loaded the module.
cheers... |

Like I said earlier, I can do an lsmod and nvidia pops up... so the module is loaded. However, it does appear that this module is the source of my problem - If I change to the vesa driver, everything's nice and happy. It just doesn't like the nvidia module.
EDIT: I feel I should provide more information...

I hope that triggers something...

Here's some more info:
I just found something else of interest... I was checking the gentoo nvidia install guide, and I found that the MTRR has an uncachable section: | Code: | rich@beastie rich $ cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size=1024MB: write-back, count=1
reg01: base=0x3ff80000 (1023MB), size= 512KB: uncachable, count=1
reg02: base=0xe0000000 (3584MB), size= 4MB: write-combining, count=1 |
Apparently, the solution to this is to change a BIOS setting... Unfortunately, my laptop only allow me to access the time and date in the BIOS... nothing further. Anyways, it worked under Mandrake... I can't imagine why it's choking to death here!
Also of note:
| Code: | rich@beastie rich $ cat /proc/driver/nvidia/agp/card
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f000e1b:0x00000000
rich@beastie rich $ cat /proc/driver/nvidia/agp/host-bridge
Host Bridge: Intel Corp. 82865G/PE/P DRAM Controller/Host-Hub Interface
Fast Writes: Supported
SBA: Supported
AGP Rates: 8x 4x
Registers: 0x1f004a1b:0x00000900
rich@beastie rich $ cat /proc/driver/nvidia/agp/status
Status: Disabled |
Note that it says the status is "disabled"

Did you compile /dev/agpgart support into the kernel? (statically or as a module?) If so, what chipset support did you use? (in the .config file, these are the "CONFIG_AGP=?" and "CONFIG_AGP_XXX=?" options).
What happens if you switch NvAgp to 2 and 1? (2 won't work unless you compiled /dev/agpgart support)
cheers... |

Hey, thanks for the quick reply!
Here's a short snippet of my kernel config: | Code: | beastie rich # cat /usr/src/linux/.config | grep CONFIG_AGP
CONFIG_AGP=y
# CONFIG_AGP_ALI is not set
# CONFIG_AGP_ATI is not set
# CONFIG_AGP_AMD is not set
# CONFIG_AGP_AMD64 is not set
CONFIG_AGP_INTEL=y
# CONFIG_AGP_INTEL_MCH is not set
# CONFIG_AGP_NVIDIA is not set
# CONFIG_AGP_SIS is not set
# CONFIG_AGP_SWORKS is not set
# CONFIG_AGP_VIA is not set
# CONFIG_AGP_EFFICEON is not set |
So yes, I compiled /dev/agpgart directly into the kernel (not a module), and I used the intel chipset. I'll try changing NvAgp to 2 and 1 and see what pops out. Again, thanks!

OK, tried setting the NvAgp option to 2, then to 1... no dice  . Anything else I could try?

Same error with NvAgp set to 1 and 2?
Also, do you have "CONFIG_4KSTACKS=y" set? IIRC, the 5336 drivers don't work with this option set. (It's in "kernel hacking" in menuconfig).
Have you thought of trying the 6111 drivers? They are masked, but I use them with no problems whatsoever. (edit /etc/portage/package.keywords and add the lines "media-video/nvidia-kernel ~x86", "media-video/nvidia-glx ~x86" and "x11-base/opengl-update ~x86") (note: the 6111 drivers work with 4K Stacks)
good luck... |

I'm not using 4k stacks, but I'll give the 6111 drivers a try anyways. Thanks

Problem solved.
Turned out I had compiled xorg-x11 with the static USE flag. This does very bad bad tings like statically linking all internal drivers (this is good) and disabling the external module loader (this is very very bad). Re-compiling xorg-x11 without the static flag solved the problem.
If there's anyone out there with similar problem, don't pull the trigger yet. It's not unsolvable  . I hope I saved someone's life with this.
