nvidia install [solved]

[sotnik]

I tried to install nvidia driver but the listbugs gives 3 errors:

b1 - #905309 - nvidia-modeset: WARNING: GPU:0: Lost display notification (0:0x00000000); continuing
serious bugs of xserver-xorg-video-nvidia (→ 390.87-3) <Outstanding>
b2 - #903121 - xserver-xorg-video-nvidia: blank screen, CPU fan goes to max and the systems freezes
serious bugs of dkms (→ 2.6.1-1) <Outstanding>
b3 - #884658 - dkms: Should really depends on dpkg-dev for dpkg-architecture

Is it safe to install?
The procedure described in the manual is up-to-date or I have to follow an other procedure.
If it is possible to add automatic installation for closed GPU drivers, will be a nice addition for the next release of siduxion.

We need more information, what video card do you have?

Post the output of

Since you already tried to install nvidia drivers, lets clean that mess up

Code Select Expand

apt purge nvidia.

Yes, make sure you include the period, very important

Remove any xorg.conf you have

Then do

Code Select Expand

apt clean; apt update; apt install nvidia-driver nvidia-driver-libs nvidia-settings nvidia-kernel-dkms


Reboot

Please post any errors

Ok thank you piper
One last question. Do I have to blacklist nouveau before or after the nvidia installation

/etc/modprobe.d/nouveau-blacklist.conf

blacklist nouveau
blacklist lbm-nouveau

This is a first time that I will install proprietary drivers for my card in linux (and first time with nvidia)

[piper]

You should see a screen about nouveau and current kernel and reboot, I forgot the exact words, I thought I had a screenshot but I don't,  just reboot

OK installed and rebooted without a problem.

nvidia-blacklists-nouveau.conf  & nvidia.conf  created automatically but not the xorg.conf (do I have to create one?)

Now I have the following two issues:
1. The characters are smaller than used to be.
I tried the following commands:

xdpyinfo | grep dots
  resolution:    96x96 dots per inch

and

xrdb -query | grep dpi
Xft.dpi:    96

but

grep DPI /var/log/Xorg.0.log
[     7.858] (--) NVIDIA(0): DPI set to (95, 94); computed from "UseEdidDpi" X config

indicate that DPI settings are wrong. How I can correct DPi in xfce desktop? (In settings the custom DPI is 96. According to some advice's in the internet I changed the value and I reverted back in 96 without any effect). 

2. In idle the fun plays between 2200 & 2500 (RPM) which is high. Is it possible to reduce the speed?

And some general questions.

   
• Do I have to repeat the procedure with kernel upgrade?
• It is reasonable to install libnvidia-encode1 & nvidia-opencl-common?

[piper]

I really don't know enough about xfce, but, here is some good reading, more than a few people here use xfce, so maybe they can chime in

You don't have to repeat the procedure with kernel upgrade

Can you post the output of

Unless you actually want/need nvidia-opencl-common libnvidia-encode1 theirs no reason to install them

Code Select Expand

apt policy nvidia-opencl-common libnvidia-encode1

I have no idea with fan speed with xfce, search-foo is your best bet

Also just now I realized the situation is even worse. Some applications have large characters and some other small, see https://imgur.com/a/qra01bb

EDIT
The problem with font inconsistencies solved after installing xsettingsd

All resolutions problems solved after creating the file ~/.Xresources and adding Xft.dpi: 96
96 is the correct DPI for my system.

Glad you have this all figured out

xorg.conf is pretty much depreciated so not needed in *most cases, their are however some exceptions
