Nvidia Driver Issue

j4media · 2021-09-17 00:32:05

Hi All,

I have an issue after installing the Nvidia drivers. After the install, my resolution appears much larger than before (especially the fonts). The resolution is identified correctly in settings. If I click on force DPI 96 in font settings, it does correct the issue, but I see that's not the recommended solution. I'm running Kernel 5.10.66-1-lts and Plasma 5.22.5. My GPU is GeForce GTX1080 and I installed nvidia-lts

Here's the desktop without Nvidia

Here's the desktop with Nvidia

Is there a better solution than forcing DPI 96 in font settings?

Thanks in advance!

Mod Edit - Replaced oversized images with links.
CoC - Pasting pictures and code

DP-4 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 607mm x 345mm

In that case you're either
1. using too big™ font pointsizes or
2. have configured wrong™ QT_SCREEN_SCALE_FACTORS/QT_SCALE_FACTOR (since it's KDE), https://wiki.archlinux.org/title/HiDPI or
3. both.

Edit: please replace the oversized images w/ thumbnails or links again (the board has a 200x200 max rule)

Ok. font pointsizes are the same I had before, nothing is bigger than 10pt. What's interesting is that Chrome seems to render correctly, so I'm thinking QT_SCREEN_SCALE_FACTOR is correct?

According to the link you provided, to adjust only font scaling it says to "force fonts DPI" in system setting. In the settings there's a disclaimer that says "The use of this option is generally discouraged", which led me down this path to begin with

The encouraged method is to configure DisplaySize in Xorg.conf. I don't have a DisplaySize parameter in my Xorg.conf file, so where would I enter that?

P.S. sorry about the oversized images, I was not aware. I updated the post to thumbnails with links.

seth · 2021-09-18 06:07:23

Don't force the font dpi.
Chrome is explicitly NOT a Qt application and will ignore the value so it's actually suggesting that the screen_scale_factor is off (or chrome just entirely DPI unaware)

The encouraged method is to configure DisplaySize in Xorg.conf.

How big is your monitor when you measure it w/ a ruler?
~60x34 cm?
In that case you don't have to configure anything here.

printenv

Lone_Wolf · 2021-09-18 12:32:54

Incase you do have to set DisplaySize, create a separate file for it in /etc/X11/xorg.conf.d folder .

Mine is called 91-monitor-Dell-U2722D.conf to ensure nothing overrides it.

Thanks Seth, when I physically measure my monitor (screen only not including bevels) I get 70x34 cm

When I printenv I noticed this:

QT_AUTO_SCREEN_SCALE_FACTOR=0
QT_SCREEN_SCALE_FACTORS=DVI-D-0=1;HDMI-0=1;DP-0=1;DP-1=1;DP-2=1;DP-3=1;DP-4=1;DP-5=1;

Does the above confirm that screen-scale-factor is off? If so, how can I fix that?

Thanks Wolf, would you be able to share what you have in that file so I can see how the code/syntax looks?

seth · 2021-09-18 16:14:33

3840x2160 is 16:9 - sure the output is 2:1?
(Or is this a situation where you realize that sticking to the imperial system was dumb? )

Qt doesn't auto-scale nor scales anything else, so that's probably not it.

Going with the screenshot your posted, the "H" in "Home" is dolphin is 16px high.
At 160dpi (which fits the 34cm height, regardless of the width) that's 1/10 of and inch.

The difference between to top of the "W" and the bottom of the "p" in "Workspace" is 21px what at 160dpi is ~1/7.6 of an inch.

10pt is 1/7.2 of an inch so actually the font sizes seem very reasonable and you have to either alter the scale or the DPI to enforce a smaller, but "wrong", size.
I'd rather not force a false DisplaySize.

j4media · 2021-09-18 16:56:37

Got it. So you're suggesting I just adjust font pt size instead of forcing DPI? For example, if 10pt is actually being calculated correctly but looks bigger than before I had Nvidia drivers installed, I should just lower pt size until it looks pleasing to me?

seth · 2021-09-18 18:51:18

Unless you run into a situation where you cannot control the font size (other than altering the DPI) - yes, that's the correct™ way to address this.
(Obviously it's your system and if you want to drive it at a logical DPI that doesn't meet the physical one, that's fine. Changing the DisplaySize however would prevent clients that reallyreallyreally want to control the real-world dimensions of what you see on your monitor from doing so since they cannot get to the actual output dimensions)

For clarity :

My monitor is 598x336 mm, resolution 2560x1440 and DPI 109x109 .

On my system X assumes a DPI of 96x96 and calculates screen dimensions using that. It then tells every application those incorrect values are the 'physical dimensions'

To get correct values I force a correct displaysize AND use Xft.dpi .

A simple test to see if X does the same on your system is to compare the dimensions in xrandr -q output with the real physical dimensions.
If they match, everything is fine.

seth · 2021-09-19 13:22:08

For more clarity ;-)
The dimensions in "xrandr -q" are supposed to be correct, those in xdpyinfo are calculated from the resolution and the given DPI.
The ones in "xdpyinfo" are "pure" X11 information (it *has* to calculate the physical dimensions this way), xrandr is an extension that uses locally available data.
If

xdpyinfo | grep dimensions

and

xrandr -q | grep connected

somewhat (there can be rounding errors) align, the DPI is "correct".

Applications™ will can the dimension from either source - how they do is an implementation detail, but most blindly rely on the availability of xrandr - so there's that
