 Posted: Wed Apr 15, 2020 12:52 pm Post subject: [SOLVED] no screens found and no opengl for eselect |
 |
|
Hi
I have a hp pavilion with a nvidia GeForce GTX 1050.
I set the kernel options according to the gentoo handbooks for X and nvidia, repsectively.
My make.conf contains (amongst others) the USE entries 'X', 'opengl', 'nvidia' ,'glut'
I built the kernel, rebooted, and did | Code: | | emerge --ask --verbose x11-base/xorg-drivers x11-drivers/nvidia-drivers |
This went through without errors.
I called 'nvidia-xconfig' to create an xorg.conf.
However, startx failed: | Code: | ~ # startx
X.Org X Server 1.20.7

Is dbus running on your system? Did you enable the dbus USE flag? |

This is correct if you enabled,and by default is enabled, libglvnd use flag.
Now is through media-libs/libglvnd that you can change opngl context.

Have you only set nvidia to the USE or both USE and VIDEO_CARDS?. you have to set :
| Code: |
VIDEO_CARDS=" nvidia"
|
in make.conf to otherwise :

This can be because your screen is attached to the intel IGPU and you have an optimus system

@hedmo: i have 'nvidia' in the use flags, and i have the entry 'VIDEO_CARDS="nvidia" in make.conf.
Is optimus system a problem for X and nvidia?
@fedeliallalinea: yes, eselect-opengl is indeed not installed, but libglvnd is. How does one use libglvnd?
@fturco: I have dbus in my USE variable in make.conf.
Indeed, dbus was not running. I started it now and did 'rc-update add dbus default'. but startx still failed (although without the dbus message).
In Xorg.0.log, after successful loading of modules glx, nvidia, fb, wfb,ramdac, there is: | Code: | [ 541.589] (II) Loading sub module "glxserver_nvidia"

Then i have also blacklisted 'nouveau' and reemerged 'x11-drivers/nvidia-drivers', and ran 'nvidia-xconfi again.
Now startx doesn't say it can't find a screen, but there is no GUI, instead there is: | Code: | (==) Log file: "/var/log/Xorg.3.log", Time: Thu Apr 16 10:03:02 2020
(==) Using config file: "/etc/X11/xorg.conf"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
The XKEYBOARD keymap compiler (xkbcomp) reports:
> Internal error: Could not resolve keysym XF86FullScreen
Errors from xkbcomp are not fatal to the X server
/etc/X11/xinit/xinitrc: line 58: twm: command not found
/etc/X11/xinit/xinitrc: line 59: xclock: command not found
|
(i emereged xterm and twm, bur i still get the same behaviour (no GUI, but xkbcomp error))
I also looked at "/etc/X11/xorg.conf" and "/usr/share/X11/xorg.conf.d", but there was no mention of 'XF86FullScreen'.
In the page https://bugs.archlinux.org/task/65730 it is mentioned that | Quote: | "The `xkeyboard-config` package introduced the new keysym `XF86FullScreen` in the recent `2.29` version ...However this symbol has not been yet added to the `libxkbcommon` package, more precisely to the file `/usr/include/xkbcommon/xkbcommon-keysyms.h`. This because the new symbol has not been added to the `xorgproto` package.
The error is temporarily fixed by reverting `xkeyboard-config` to `2.28` because this version does not have the new keysym. " |
Problem is, when i do 'eix xkeyboard-config' the lowest available version *is* 2.29. How could i get a lower version of `xkeyboard-config`?
Or is there another way to solve this problem? ¨ |

I can switch, in my prime system, from intel to nvidia through libglvnd with this configuration:
| Code: | # echo 'Section "ServerLayout"
Identifier "layout"
Option "AllowNVIDIAGPUScreens"
EndSection' > /etc/X11/xorg.conf.d/30-nvidia-offload.conf |
then restart X and for run a program with nvidia you can run
| Code: | | __NV_PRIME_RENDER_OFFLOAD=1 __VK_LAYER_NV_optimus=NVIDIA_only __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo |

i have now removed the line | Code: | | key <I380> { [ XF86FullScreen ] }; |
from '/usr/share/X11/xkb/symbols/inet'.
After startx, the X still does not start properly (the console is still visible, with the normal start-up messages from X, but *no* error messages at all).
The logfile /var/log/Xorg.0.log likewise has no error entries, but there are some warnings: | Code: | ~ # grep WW /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.

On the other hand X is running as are twm, xterm and xclock, but not even a black screen is visible, only the console. Her an excerpt from 'ps ajxf' during this state: | Code: | 1 3077 3077 3077 tty1 3359 Ss 0 0:00 /bin/login --

3384 3421 3421 3421 pts/2 3421 Ss+ 0 0:00 \_ bash |
So the questions are: without error messages, how can i find out what is wriong, and how can i get to have a 'visible' X.? |

jody did you check optimus ?
| Quote: |
Before starting X
Per NVIDIA's instructions, the following commands are required before starting X:
| Code: | XRandR commands:
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
|
This is to say any Display Manager that starts X-Windows then asks the user to log in will result in a black screen unless the above xrandr commands are run before asking the user to log in.

Thanks for the link to the optimus wiki.
I rebuilt the kernel after checking the required options, reemerged x11-base/xorg-server and x11-drivers/nvidia-drivers and ran | Code: | ~ # nvidia-xconfig --prime
Using X configuration file: "/etc/X11/xorg.conf".
X Configuration file set up for PRIME. Please run "xrandr --setprovideroutputsource modesetting NVIDIA-0" and "xrandr
--auto" to enable. See the README for more details.
Option "AllowEmptyInitialConfiguration" "True" added to Screen "Screen0".
Backed up file '/etc/X11/xorg.conf' as '/etc/X11/xorg.conf.backup'
New X configuration file written to '/etc/X11/xorg.conf' |
But the xrandr command fails: | Code: | ~ # xrandr --setprovideroutputsource modesetting NVIDIA-0
Can't open display |
What could be the problem here? |

The xrandr commands has to be in a file. lets say you are running X via startx and you have chosen lxde as the DE then the /etc/X11/xinit/xinitrc file
will look like this:
| Code: |
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
exec startlxde
|
at the top
For me...i am using sddm and have to set the commands to the /usr/share/sddm/scripts/Xsetup file and protect it from overrides |

I put the two 'xrandr' lines at the top of /etc/X11/xinit/xinitrc, then called 'startx'
-> X started properly  (with the twm windows manager showing terminals and a clock)
Now i can continue setting up my laptop.
Thanks a lot for your help! |

| xrandr does not need to be in a file, but it does need to be run in a context where it can connect to the X server. That means your X server must be up, your $DISPLAY must be pointed to it, and your Xauthority data must allow xrandr to connect. Due to its intended use for starting X programs, xinitrc fulfills all those requirements. |
