 Posted: Wed Dec 22, 2021 2:31 pm Post subject: Nvidia display card issue,SOLVED by emerge -e nvidia-drivers |
 |
|
I followed the Gentoo KDE setup guide to install Plasma 5. It was using for around two months without issues.
Recently after I upgraded my kernel from 5.10.52 to 5.10.76, KDE Plasma does not start automatically. I was trying to find which part is going wrong. And I found that my display manager status is crashed. What else I can do to fix this?
Thanks a lot.

Try
| Code: |
emerge -1av gui-libs/display-manager-init sddm
dispatch-conf
|
and make sure in
| Code: |
/etc/conf.d/display-manager
|
you have
| Code: |
DISPLAYMANAGER="sddm"
|
IMPORTANT:
Enable "dbus"
| Code: |
rc-update add dbus default

alamahant,
Thank you for reply and help.
I have just emerge -1av gui-libs/display-manager-init and sddm, then dispatch-conf. Yes in /etc/conf.d/display-manager I always have CHECKVT=7 and DISPLAYMANAGER="sddm".
I have just also add dbus to default rc. dbus is having the status started. But display-manager is still crashed even I restart it, or reboot the PC.

Can you try with lightdm?
Replacing sddm with lightdm in /etc/conf.d/display-manager
Also in /var/log do you see any sddm log.
For example in my case there is a /var/log/lightdm directory.
Plz look at your sddm log if any.
Can you use startx to start plasma?

alamahant,
I think it may be a problem of me using the Nvidia 1650 display card. I am looking into the Kernel Mode Setting thing, as some say it may fix the sddm : Failed to read display number from pipe problem. I think KMS is a good thing as it will allow me to switch to Ctrl+Alt+F2 and back to Ctrl+Alt+F7 smoothly.
It is strange that I was using the same Nvidia 1650 card without issues, until a upgraded the kernel and did a few times emerge world.

Do you have an

file?
You need it for nvidia..

Did you rebuild nvidia after updating the kernel?
| Code: |
emerge @module-rebuild

Not sure why the NVIDIA driver is not enabled in the kernel. Just enabled and rebuilding. Fingers-crossed. Thanks for helping!

It may be the case that the kernel part is done. However the xorg DDX driver seems to be lagging behind with only Pascal based systems as their max and very few commits in the past 2 years. |

Thanks grknight. It appears that nouveau does not support GTX 1650 (NV167) yet.
So I just followed the Gentoo Nvidia drivers guide to configure to use the proprietary Nvidia drivers. However I still cannot do startx.
| Code: | # startx
# less /var/log/Xorg.0.log
... the last few error lines ...

After I recompiled the kernel, genkernel initramfs, updated /etc/portage/make.conf to VIDEO_CARDS="nvidia", changed /etc/X11/xorg.conf to Driver "nvidia", then emerge pulled in the new video card configurations, while removing nouveau. And rebooted.
I found it is weird that I do not have the nvidia.ko module(s). Is it possible that the proprietary Nvidia driver not yet supports the gentoo kernel 5.10.76?
How to check which versions of kernel do the proprietary Nvidia driver support?
| Code: | # find /lib/modules/5.10.52-gentoo/ -type f -iname '*.o' -or -iname '*.ko' | grep nvidia
/lib/modules/5.10.52-gentoo/video/nvidia-peermem.ko
/lib/modules/5.10.52-gentoo/video/nvidia-drm.ko
/lib/modules/5.10.52-gentoo/video/nvidia-modeset.ko
/lib/modules/5.10.52-gentoo/video/nvidia.ko
/lib/modules/5.10.52-gentoo/video/nvidia-uvm.ko
# find /lib/modules/5.10.76-gentoo-r1/ -type f -iname '*.o' -or -iname '*.ko' | grep nvidia
# (nothing found)
# modprobe nvidia
modprobe: ERROR: could not find module by name='nvidia'
modprobe: ERROR: could not insert 'nvidia': Unknown symbol in module, or unknown parameter (see dmesg)
# dmesg | grep nvidia
# (nothing found) |

I do not mind using not the newest kernel. But I cannot get back the 5.10.52 source anymore.
FYI I have checked Nvidia driver version 470.86 supports my card GeForce GTX 1650.

Dear all who have been generously helping me,
The good news is, after I emerge -eva nvidia-drivers, I can get back into KDE Plasma now. Everything in Plasma is running normal. It recognises my Nvidia GeForce GTX 1650 as before. It is like a good Christmas present to me. Thank you very much!
The emerge -eva nvidia-drivers took literally 30+ hours. I am not sure how it fixed my issue. Nevertheless, I can continue my work in GUI (after Christmas).
PS - Nouveau should be supporting GTX 1650. I will try switching to nouveau later.
These issues took me a week. But I have learnt a lot along the way. Thanks again to all the amazing guys who have been with me. You are my HEROES!!
Merry Christmas & Best Regards,

Jaglover,
I did. But it did not work.
I guess it is because I was using nivdia-drivers when I was at the old kernel. (I do not remember it. But in the configures it seems so.) Then I lost the old kernel source by emerge --depclean. After upgrade to new kernel, I opt to use nouveau. Yes I have problem with this. But now I am sure nouveau supports my card, I will try it later. I prefer nouveau.
As I read somewhere, the nivdia-drivers is compiling against the kernel souce. I had times that old source is missing, dangling symlink, unbuilt new source. I guess these made me switching back from nouveau to proprietary fails again.
Anyway, now I am using slot to keep the old kernel source just in case.

I was using 5.10.52 and unintentionally upgraded to 5.10.76-r1. Unfortunately 5.10.52 is no longer available through emerge.
Now I know 5.10.x are both the same kernel just with more security patches. Now I know the problem must be elsewhere. But I did not know about it and just wanted to roll back to a working stage.
Thanks for the remark about nouveau.

For your information, I have just updated the kernel from 5.10.76-r1 to 5.10.88. There is absolutely no new options in the kernel config between these two subversions. However KDE Plasma refused to start after a reboot. startx did not work neither. The log message was like "nvidia cannot find my screens" or so *.
It was fixed after a emerge -av nvidia-drivers. I am not sure the reason but as the gentoo nvidia wiki says (the nvidia-drivers) will compile against the Linux kernel. I guess we have to re-compile the nvidia-drivers after a kernel upgrade/change.
* It seems it only keeps the latest log, so I cannot trace back the exact error happened a few boots ago.
* Yes I am using the proprietary nvidia-drives at the moment.

The command to rebuild modules is 'emerge @module-rebuild'. You should not emerge nvidia-drivers as you did, now it is in your world file. In properly configured Gentoo system the drivers are pulled in automatically. VIDEO_CARDS="nvidia" - this is the variable which controls it. Polluted world file can and will lead to weird conflicts and updating problems.

Dear Jaglover,
Thank you for reply. I will use emerge @module-rebuild next time.
x11-drivers/nvidia-drivers is already in my world file after setup. Will it be a problem? Should I emerge --deselect nvidia-drivers?
Yes I have VIDEO_CARDS="nvidia" in /etc/portage/make.conf .
I am not sure if this is a problem that I cannot find the nvidia.ko file. But it seems working normally.
Oh yes I have over-read the important note in the gentoo nvidia wiki. Thanks Jaglover again.

Every time a kernel is built, it is necessary to reinstall the NVIDIA kernel modules. An easy way to rebuild the modules installed by ebuilds (such as x11-drivers/nvidia-drivers) is to run emerge @module-rebuild. |

The world file should contain only packages you have directly installed. Dependencies do not belong there. You could back up your world file and then use a text editor do delete all lines which do not belong there. Followed by 'emerge -ac'.

But I do need nvidia-drivers. So it is no harm to have it in the world file, is it?

On a side-note, given this is a recurring issue (even though it's not specific to nvidia-drivers, but any out-of-tree modules), I decided to add this that will be displayed the first time install nvidia-drivers from now on (and later available in /usr/share/doc/nvidia-drivers*/README.gentoo*):

As it mentions, an alternate route to re-emering manually is using distribution kernels that give you a built kernel rather than just sources (also mentioned in the handbook), and then adding dist-kernel to your make.conf's global USE. This will cause nvidia-drivers to be automatically rebuilt when upgrading the kernel. This is a newer way to do things, so it tend not to get used as much or be well known.

It's fine, although still generally good practice to not have "dependencies" in your world file and rather only applications you use directly (e.g. a web browser rather than all the libraries/drivers it uses).
In this case VIDEO_CARDS=nvidia tells xorg-drivers package to keep nvidia-drivers installed already (and will remove it if you change that to another card). And if for example a brand new shiny nvidia-better-drivers package was added it may give confusing errors and may have to update your world file.. not that it's happening but well |
