you're not gonna notice 15 Hz difference on an LCD/OLED screen

viral wedge you're not gonna notice 15 Hz difference on an LCD/OLED screen

i have a 75 hz monitor and i can easily tell the difference

#

are you using an nvidia gpu?

#

those have issues when creating/applying custom modes with xrandr

trail coral Oct 27, 2024, 7:57 PM

#

real ingot are you using an nvidia gpu?

Yeah

trail coral Oct 27, 2024, 7:57 PM

#

real ingot those have issues when creating/applying custom modes with xrandr

No kidding

viral wedge Oct 27, 2024, 8:41 PM

#

yeah secure boot must be off before applying nvidia drivers

#

in otherwords, use open source driver; shut down; power up - go to BIOS , and turn off secure boot; then boot to the distro and switch to nvidia driver; then final reboot to finalize.

How to set a Custom Screen Resolution in Linux

In this video I will show you How to set a Custom Screen Resolution in Ubuntu Linux.

Commands used in the video (watch the video as some commands could be different in your case):
xrandr
cvt 1920 1080
sudo xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1088 1120 -hsync +vsync
sudo xrandr --addmode Virtual1 "1920x1080_60....

this does not work with nvidia gpus, they cant create modes with xrandr even with the drivers properly applied

All this to change my refresh rate

#

Bro I hate nvidia right now

#

I mean I usually do

#

But I hate them a lot rn

xrandr --addmode DVI-D-0 1600x900_76.00 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 25 Current serial number in output stream: 26

#

is dvi-d-0 an invalid parameter?

#

idk I don't usually mess with xrandr

#

Monitor is an Emachines E202HV btw

trail coral Oct 29, 2024, 2:36 AM

#

I have an idea but it's kinda hacky, what if I do 1280x1024 at 75.02hz and upscale to 1600x900?

#

idk I'm grasping at straws here

#

I might just try wayland, idk I never used it before

#

I heard it's kind of weird on nvidia cards

#

Hell I probably wouldn't be here if I was using an amd card it would probably just work

#

Pardon me ranting I'm very tired, I'm going to lie down, maybe when I wake up I will have an epiphany

tame pine Oct 29, 2024, 3:16 AM

#

Honestly this is less an issue with nvidia and more of an issue that the computer industry decided to turn on secure boot by default

#

There are actually other points of failure to find if you have secure boot on because you just straight out can't build modules to be loaded on your own computer

The super hacky solution is a non-starter.

#

To offer better assistance you should share the results of inxi -Fxxxrzc0 and mokutil --sb-state

#

you might need to install mokutil

trail coral Oct 29, 2024, 5:53 AM

#

📎 message.txt

#

mokutil --sb-state
EFI variables are not supported on this system

#

I dunno what secure boot has to do with any of this

#

All I want to do is change my refresh rate

#

How is that not secure?

tame pine Oct 29, 2024, 5:58 AM

#

secure boot prevents the nvidia driver from even loading

trail coral Oct 29, 2024, 5:59 AM

#

How is the nvidia driver not loaded when I'm using it?

tame pine Oct 29, 2024, 6:00 AM

#

it was worth checking because in fact its possible to use your nvidia card without the proper driver loaded

#

but it might in fact not work properly

#

EFI variables not being supported in this system means you installed in legacy mode which is not harmful to our present issue

#

most motherboards since 2008 support EUFI but they also have a compatibility mode where they pretend to be old school bios to support legacy software

trail coral Oct 29, 2024, 6:05 AM

#

Cool

tame pine Oct 29, 2024, 6:06 AM

#

So the one reference to your monitor says 60hz is the native refresh rate

#

oh I understand your issue

#

you have 2 monitors 75 and 60 hz respectively right?

trail coral Oct 29, 2024, 6:08 AM

#

I know it can do 76 1600x900, I did it on windows, I know it's not the factory setting

trail coral Oct 29, 2024, 6:08 AM

#

tame pine you have 2 monitors 75 and 60 hz respectively right?

Just the one monitor

tame pine Oct 29, 2024, 6:08 AM

#

X and Ebay both say its 60hz

trail coral Oct 29, 2024, 6:10 AM

#

Yeah out of the box

tame pine Oct 29, 2024, 6:10 AM

#

ok its own manual says it does 1600x900 at 60 hz

#

its not about out of the box its period

#

it can do 75hz at 1152x864

#

which is also what X is saying

#

dumb question but I see 2 monitors in xrandr output is it literally connected to both cords?

Are you talking about the hdmi thing? That's just what happens when I try adding modes, it adds them as hdmi instead of dvi-d-0

tame pine Oct 29, 2024, 6:13 AM

#

you can't actually add modes the hardware doesn't support

trail coral Oct 29, 2024, 6:14 AM

#

It literally works on windows

tame pine Oct 29, 2024, 6:16 AM

#

did you use xrandr --addmode and specify the correct output?

#

eg xrandr --addmode DVI-D-0 rest of command

#

If you do everything correctly and get an error it means it can't be made to work

#

due to being unsupported

trail coral Oct 29, 2024, 6:24 AM

#

Every time I add a new mode it falls under hdmi-0

#

make a new mode

#

I can't even perform addmode

tame pine Oct 29, 2024, 6:27 AM

#

are you literally specifying DVI-D-0

trail coral Oct 29, 2024, 6:27 AM

#

How do I do that when I make a new mode if that's possible?

tame pine Oct 29, 2024, 6:27 AM

#

Did you read the link I posted from unix.stackexchange.com

trail coral Oct 29, 2024, 6:28 AM

#

Let me read it again

tame pine Oct 29, 2024, 6:31 AM

#

basically gtf 1600 900 75 will output something like 2 lines of text the second line will start with Modeline you copy everything after the word modeline

#

then run xrandr --newmode SHIT_YOU_COPIED

trail coral Oct 29, 2024, 6:31 AM

#

Already did that

tame pine Oct 29, 2024, 6:32 AM

#

then you do xrandr --admode DVI-D-0 "1600x900_75.00"

trail coral Oct 29, 2024, 6:32 AM

#

cannot find mode

tame pine Oct 29, 2024, 6:32 AM

#

so it will never ever work

trail coral Oct 29, 2024, 6:32 AM

#

Dumb, works on windows

tame pine Oct 29, 2024, 6:33 AM

#

It's not what the monitor was ever supposed to be able to do in any case

#

It would be funny as hell if windows just told you it was refreshing 25% faster knowing you are probably among the 99.99% of people who cannot visually distinguish between 60 and 75hz

trail coral Oct 29, 2024, 6:34 AM

#

I mean, it is 15fps, I guess it's not a huge diffference

tame pine Oct 29, 2024, 6:34 AM

#

well on net Linux is able to do what the spec sheet says it ought to do

#

and its a 12 year old monitor worth aprox 99c

#

there are 144hz monitors on facebook market in my area that are only 5 years old for $50

trail coral Oct 29, 2024, 6:35 AM

#

If I had $50 for a new monitor I probably wouldn't be having this discussion

tame pine Oct 29, 2024, 6:36 AM

#

There are 1080p monitors at my local thrift store for $5

trail coral Oct 29, 2024, 6:36 AM

#

They don't sell electronics at ours because they're too cheap to test and tag stuff

#

Which I think is a requirement here

tame pine Oct 29, 2024, 6:38 AM

#

I would make peace with 60hz

#Can't do 1600x900@75hz even though I know my display supports it
