PostPosted: Tue Oct 15, 2013 7:58 am    Post subject: [Solved]No device detected while startx? Reply with quote

I've read almost all related posts on this forum but no luck!

No device detected seems some other framebuffer drivers take over the hardware ?

I have installed Xorg following the Wiki here : http://wiki.gentoo.org/wiki/Xorg/Configuration

One thing different is I didn't disable all other framebuffer drivers as the Wiki says. Because I
use EFI, I have to enable the EFI framebuffer or it will render blank screen while booting.


And worse, I couldn't enable
Code:

Device Drivers --->
  <*> Intel 8xx/9xx/G3x/G4x/HD Graphics
  [*]   Enable modesetting on intel by default


Because it will render black sreen while booting either.

Any idea? Thanks !

So,...
FB_EFI shouldn't be a problem.
I don't have a laptop, so I can't tell much except of a few things I've learnt here.
For the time being, it might be a good idea to provide the driver for intel card, regardless on nvidia.
It might be that your card is too recent for nouveau driver (or at least this version), cause if I'm googling right, it's GeForce GT 755M.

lcx,

From your Xorg log, you appear to have an Optimus laptop.
Your log shows
Code:
[  7284.979] (--) PCI:*(0:0:2:0) 8086:0416:17aa:3801 rev 6, Mem @ 0xc2000000/4194304, 0xb0000000/268435456, I/O @ 0x00005000/64
[  7284.979] (--) PCI: (0:1:0:0) 10de:0fcd:17aa:3801 rev 161, Mem @ 0xc0000000/16777216, 0x90000000/268435456, 0xa0000000/33554432, I/O @ 0x00004000/128, BIOS @ 0x????????/524288
which includes an Intel and nVidia graphics chips.

The Intel one is a complete graphics system. It can write new images in the pixel buffer and read the pixel buffer out to the dispaly.
The nVidia graphics can only write new images in the pixel buffer. It has no way to get the pixel buffer onto the screen.
This means that for low power/performce you use the Intel system.
For high power/performance you use the Intel system to refresh the screen and the nVidia chip to draw in the pixel buffer.

Make the Intel graphics work first. Then either use the Bumblebee project, as mentioned by others, or add the nVidia binary blob driver.
Its README file tells how to make it work with an Optimus graphic system. From memory, around chapter 33.

Hmm, as I said in the question, when I built the driver support for my intel card. I got a black screen while booting.
So I have to turn it off...

Correct ! Then you mean a live nouveau driver may solve this problem?[/quote]

Thanks, NeddySeagoon,

The drvier for my Intel integrated card is i915. But as I said in the question, when I enable these two options:

Code:

Device Drivers --->
  <*> Intel 8xx/9xx/G3x/G4x/HD Graphics   # CONFIG_DRM_I915
  [*]   Enable modesetting on intel by default    # CONFIG_DRM_I915_KMS


My system got black screen shortly after booting. I don't know if it conflicts with EFI framebuffer driver

Then I just turn off all noveau driver options to make Intel graphics work first or
just a configuration is enough? Any references?

And what do you by chapter 33? What book is it?

You need to read a guide aimed specifically at laptops and a recent one at that - it seems you have a muxless laptop and those have began to be fully handled only recently.
Looking at the upstream repo, live ebuild won't help (not enough more recent commits). But if - as NeddySeagoon says - it's a muxless laptop, then the whole problem comes from not yet working intel card.
Make sure your libdrm/mesa has correct useflags (might not be the immediate problem, but it's good to be prepared).

Thanks, but once I configured in the Intel card driver(i915), my screen turns black shortly after booting.
even I removed the nouveau driver config option .

Any suggestion? Thanks.

Will your laptop boot a Ubuntu Live CD, or Debian LiveCD etc :?: If so, boot it and look at the dmesg produced and attempt to replicate it on your gentoo install...

Thanks for your help.

Isn't gentoo miniCD or SystemRescueCD good? I don't quite understand what do you mean by "replicate".

Boot into Ubuntu LiveCD, or Knoppix. After Booting Choose Use Live CD(the opposite of the install option) Start a term and type dmesg. Search through the dmesg untill you find the section that loaded the video driver...

My hardware is pretty new and even Ubuntu 13.10 version LiveCD gives a black screen after booting.

After some searching, I found the black screen (both under my situation with intel drvier builtin and under Ubuntu LiveCD booting) maybe caused by the insane graphic card behaviour under UEFI booting system , so I passed the nomodeset kernel option and chaged the boot mode from UEFI mode to Legacy Mode(supporting bios). Gratifyingly, black screen during booting is away even I built in the Intel driver.

And then I moved on to startx. This time the Xorg.0.log is quite different from the original one I posted on this thead. I put the new one here:
http://pastebin.ca/2472214

It seems it could not find a driver ?

I have builtin in the Intel graphics driver
Code:

Device Drivers --->
  <*> Intel 8xx/9xx/G3x/G4x/HD Graphics
  [*]   Enable modesetting on intel by default


and the nouveau driver
Code:

<*> Nouveau (nVidia) card


And it indeed didn't load the nouveau driver(the lspci -k dont tell nouveau in use, dmesg have nothing about nouveau)
I didn't block nor blacklist the nouveau driver.

Follow Neddy's advice here, you cannot use the nouveau driver . If you want to use both you must use the Bumblebee Project, or the Binary NVIDIA Drivers in tandem with the intel driver

To make xf86-video-intel work, you need - at minimum - to drop 'nomodeset' from bootloader options.
It seems though, that you don't have the driver installed in the first place.

Hi, what is xf86-video-intel? The driver for Intel card? Then what are that driver i915 for?

I couldn't drop the nomodeset option, though Intel and nouveau all need KMS...
Because dropping it will caused black screen when i915 is built in...

Intel915 is the correct driver, leave everything as it is, passing nomodeset as you stated earlier, and add the bumblebee.

lcx,

The intel graphics driver is in two parts.
The kernel part provides the frame buffer console and cooperates with the xorg part which is provided by Xorg.
You need to set your VIDEO_CARDS in make.conf

You need both parts of the driver to make Xorg work

You need both parts of the driver to make Xorg work



Thanks NeddySeagoon and other good guys.

I've installed the Intel driver xf86-video-intel(by add an intel in VIDEO_CARDS).

This time it again complains about No devices detected. Since the Intel card
is a complete video card to work well and I have buit the kernel part i915(as module)
and installed the X part xf86-video-intel, I quite don't understand why it still complains this issue.


Then I thought of that I passeed the nomodeset parameter in bootloader(as I
stated in previous post, otherwise I got a black screen at booting.)

And I found on other threads in this forum saying that KMS is mandatory for recent xf86-video-intel
, so I thought that this maybe the problem and installed the generic driver xf86-video-modesetting,
it did find the devices! But some other errors :
Code:

[   588.827] (EE) open /dev/dri/card0: No such file or directory
[   588.827] (WW) Falling back to old probe method for modesetting
[   588.827] (EE) open /dev/dri/card0: No such file or directory
[   588.827] (EE) Screen 0 deleted because of no matching config section.
[   588.827] (II) UnloadModule: "modesetting"
[   588.827] (EE) Device(s) detected, but none match those in the config file.
[   588.827] (EE)
Fatal server error:
[   588.827] (EE) no screens found(EE)
[   588.827] (EE)

(the complete one is here: http://pastebin.ca/2472545)

I have checked this : http://forums.gentoo.org/viewtopic-t-916514-start-0.html
NeddySeagoon mentioned this:
Code:
Turn off any hardware framebuffer drivers.
Turn on Intel in agpgart and in DRM in the kernel.
Turn on KMS (Kernel mode setting) under one of the intel options.

1. I have only EFI fb driver.
2. Yes. But dmesg | grep drm : [drm:drm_pci_agp_init] *ERROR* Cannot initailize the agpart module.
3. Yes, CONFG_DRM_I915_KMS=y. But I turned it off via nomodeset kernel parameter.

Any suggestion? Thanks.

Your over complicating this whole thing:
  1. Add intel to VIDEO_CARDS
  2. Remove xf86-video-modesetting
  3. Leave the i915 as a module
  4. Pass nomodeset=1 in your kernel command line

This point is wrong.

But it seems a basic question needs to be asked: what is the output of:
'emerge -1pv media-libs/mesa x11-libs/libdrm x11-base/xorg-server x11-drivers/xf86-video-intel' ?

I couldn't drop the nomodeset option, though Intel and nouveau all need KMS...
Because dropping it will caused black screen when i915 is built in...


Void, please read the previous posts, enabling modesetting causes the black screen the OP wants to get rid of.

nomodesetting=0 enables
nomodesetting=1 disables
