[Solved] Xorg: screens found, but...

Hello again. It's the Xorg trouble again. After executing 'startx', I get "Screens found, but none have a usable configuration" error.

I have Lenovo y510p with Nvidia GT 755M (NVE7, GK107) and onboard Intel, that I cannot disable in Bios.
I downloaded nvidia-340xx driver (correct?).
Arch is dualbooting with Win7, is still fresh for I have little time to fool around. I googled this and my head is still spinning so I finally chose to ask for advice.

Here's Xorg.0.log:

The idea is to get some web browser running so I can use just one computer to fool around with Arch.
Thanks.

(Edited for correct xorg log. I hope.)

Re: [Solved] Xorg: screens found, but...

I downloaded nvidia-340xx driver (correct?).

I sincerely hope "downloaded" means : i used pacman to install the nvidia-340xx-lts driver.
If not, you are making things diffcult for yourself and it might be easier to start over from scratch.

[    40.037] Current Operating System: Linux explorer 3.14.44-1-lts #1 SMP Sat Jun 6 20:26:18 CEST 2015 x86_64

latest lts kernel in repo is 3.14.45 , run pacman -Syu .

Which nvidia driver :
according to Nvidia site, your card is in the GeForce 700M Series (Notebooks) family and supported by the latest driver, 352.21 .
remove the nvidia-340xx-lts driver, and install nvidia-lts instead .

Also install xf86-video-intel driver.

Re: [Solved] Xorg: screens found, but...

Yes, I did use "pacman -S" to install the drivers. Fortunately smile
Kernel updated.

Is there a way to tell pacman to remove all things nvidia? So that I can be sure I only have installed what I really need; I removed (pacman -R) nvidia-340xx-lts and installed nvidia-lts, but no joy (I'd say the same error).

Lone_Wolf wrote:

I did, and there still is a warning in xorg log that i915 module is not found (?).

Also, I wrote

Option "ConnectedMonitor" "DFP"

to xorg.conf in Device section. I got no error even when I wrote down bull instead of "DFP".

So, how bad is it to execute
nvidia-xconfig --query-gpu-info
and get 

WARNING: Unable to use the nvidia-cfg library to query NVIDIA hardware.
ERROR: Unable to query GPU information.

I just wish I missed something basic and could get on with it.

Re: [Solved] Xorg: screens found, but...

I'm beginning to suspect that your laptop is using Nvidia Optimus technology.

Do yo see Optimus anywhere on the laptop case ?
Is the intel gpu integrated with the processor ?

If this is a Nvidia Optimus system, check https://wiki.archlinux.org/index.php/NVIDIA_Optimus

Optimus nowhere. Don't know about integration; but I'll try the Optimus setup anyway...

Re: [Solved] Xorg: screens found, but...

The intel gpu is integrated in cpu (i7).
So, I tried the Bumblebee; and I feel like going for a clean install of Arch, just to make sure.

optirun glxgears -info:

[ERROR]Cannot access secondary GPU - error: [XORG] (EE) systemd-logind: failed to get session: PID 454 does not belong to any known session
[ERROR]Aborting because fallback start is disabled.

Same with glxspheres64.

Was it possible for "Xorg.8.log" to be created or is it just my doing? Anyway, still no luck.

Re: [Solved] Xorg: screens found, but...

Ok, i'm thinking the xorg.conf you posted may be the issue.

I'd like you to try 2 things :

-   rename / move the xorg.conf temp so X tries to do autoconfiguration.

- put the xorg.conf back in place, but comment out Inactive "intel"

post both logs, comparing them should give some clues.

And also post lspci -v output.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [Solved] Xorg: screens found, but...

Hello and thanks for answering.
I don't know how you did it, but you broke my X. I had a nice long post ready, showing (not explaining) all I did so that X ran under root (not under user) with xorg.conf deleted. Then I ran lspci -v and all went to hell again.

Here's Xorg.0.log of succesful session (xorg.conf deleted):

This makes me confused! (Ihaven't looked at the logs myself yet, as I am caught by surprise and try to answer asap.)
Thanks for any input.

note I: After installing xorg related pkgs and bumblebee intel/nvidia pkgs, I followed instructions here: https://bbs.archlinux.org/viewtopic.php … 0#p1326090
except 1) and I added to /etc/bumblebee/xorg.conf.nvidia:

Section "Screen"
Identifier "DefaultScreen"
Device "DiscreteNvidia"
EndSection

This seem to have some effect on X behavior.
I should mention that I added some 'xrandr' lines into .xinitrc. To what effect...

Thx.

EDIT: F**K me now. I tried running startx with and without xorg.conf with 'Inactive intel' un-commented, it works like a charm (root and user), though the screen still goes less bright during startup. 'glxspheres64 at double the previous fps. I'm comitting myself to the nearest asylum.

Re: [Solved] Xorg: screens found, but...

No need for asylum visit, it does seem your system needs the intel card to be active to have screens at all.

bumblebee appears to be only method for you to use the nivida card, and not the intel one.
That suggest your laptop is indeed an Optimus system.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Re: [Solved] Xorg: screens found, but...

But why the unreliability? One time it runs, second it doesn't. Any hints?
