Monitor not being picked up in linux mint | Linux Mint Community🍵 | Page 1

#

So I just recently downloaded linux mint cinnamon, and when I go to the display settings to change my monitor's refresh rate from 60hz to 144hz it says "unknown monitor" and i cant change the refresh rate, i have a nvidia 3060 gpu paired with an intel i5-12400f and ive downloaded the drivers from the driver manager

Try inxi -G
This will show information about your graphics card and drivers.
If you see nouveau and have an NVIDIA GPU, installing proprietary drivers might help.
Go to Menu Driver Manager and check if a proprietary driver is available. u can also try xrandr to see if ur monitor is detected if it is but not configured as u wished then u can do cvt (your res) (refresh rate) so for me it would be 2560x1440 144 this is going to output a Modeline copy everything after modeline and then do xrandr --newmode "(resolution of ur screen)(refresh rate)" (paste the Modeline here)
xrandr --addmode HDMI-1 "(resolution of ur screen)(refresh rate)"
xrandr --output HDMI-1 --mode "(resolution of ur screen)_(refresh rate)" replace HDMI-1 by your correct display name from xrandr
or u can also see cat /var/log/Xorg.0.log | grep -iE "error|warning" to see if there is any errors or unormal things

tepid island Feb 8, 2025, 2:51 PM

leaden comet Try inxi -G This will show information about your graphics card and drivers. ...

when i run inxi -G it shows device 1 (my gpu)
and device 2: my facecam

#

and when i do xrandr it says this:

#

Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 4096 x 4096
None-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1920x1080 60.00*+

leaden comet Feb 8, 2025, 2:52 PM

#

t looks like your system is not correctly detecting your display. The None-1 output in xrandr suggests that Xorg is not recognizing your monitor properly, which is why you can't change resolution or refresh rate.

#

hmm

tepid island Feb 8, 2025, 2:53 PM

#

hm

leaden comet Feb 8, 2025, 2:53 PM

#

can u try inxi -Gxx

tepid island Feb 8, 2025, 2:53 PM

#

sure

leaden comet Feb 8, 2025, 2:54 PM

#

to see if ur GPU drivers are installed

oh wait

#

i have an idea

tepid island Feb 8, 2025, 2:55 PM

#

yeah

leaden comet Feb 8, 2025, 2:55 PM

#

do echo -e "blacklist nouveau\noptions nouveau modeset=0" | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
in a terminal

tepid island Feb 8, 2025, 2:55 PM

#

what would that do?

leaden comet Feb 8, 2025, 2:56 PM

#

disable "Nouveau"

tepid island Feb 8, 2025, 2:57 PM

#

ok

leaden comet Feb 8, 2025, 2:57 PM

#

done ?

tepid island Feb 8, 2025, 2:57 PM

#

it just says

blacklist nouveau
options nouveau modeset=0

leaden comet Feb 8, 2025, 2:57 PM

#

its normal dont worry

#

now do sudo update-initramfs -u

tepid island Feb 8, 2025, 2:58 PM

#

ok

#

says this

update-initramfs: Generating /boot/initrd.img-6.8.0-52-generic

#

nothing else

unkempt valve Feb 8, 2025, 2:59 PM

#

popcorncat

leaden comet Feb 8, 2025, 2:59 PM

#

wait that it finishes and then u can reboot

tepid island Feb 8, 2025, 2:59 PM

#

yeah now it shows the line be fore u put in a command

leaden comet Feb 8, 2025, 2:59 PM

#

with sudo reboot

#

once u have done this u can do nvidia-smi
and it should give u information about ur nvidia gpu

tepid island Feb 8, 2025, 3:02 PM

#

ok i just rebooted, lemme test it out

leaden comet Feb 8, 2025, 3:02 PM

#

wait

#

try glxinfo | grep "OpenGL version"

tepid island Feb 8, 2025, 3:02 PM

#

which one should i do first

leaden comet Feb 8, 2025, 3:02 PM

#

nvidia-smi and then glxinfo | grep "OpenGL version"

tepid island Feb 8, 2025, 3:03 PM

#

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

#

but i have the most recent driver installed

leaden comet Feb 8, 2025, 3:03 PM

#

can you do dpkg -l | grep nvidia

#

in a terminal

tepid island Feb 8, 2025, 3:04 PM

#

ok it shows me a bunch of stuff

#

leaden comet Feb 8, 2025, 3:06 PM

#

hmmm

#

i may have an idea but not really sure if it would function proprely

tepid island Feb 8, 2025, 3:06 PM

#

has anyone else had an issue like this before?

leaden comet Feb 8, 2025, 3:06 PM

#

alot of people

tepid island Feb 8, 2025, 3:07 PM

#

leaden comet Try inxi -G This will show information about your graphics card and drivers. ...

i havent tried the xrandr newmode thing yet

leaden comet Feb 8, 2025, 3:07 PM

#

even myself but a long time ago

#

oh then u can try to do so

tepid island Feb 8, 2025, 3:08 PM

#

should i do cvt (your res) (refresh rate)

#

so cvt 1920x1080 144

leaden comet Feb 8, 2025, 3:08 PM

#

try xrandr to see if ur monitor is detected

tepid island Feb 8, 2025, 3:09 PM

#

leaden comet try xrandr to see if ur monitor is detected

leaden comet Feb 8, 2025, 3:09 PM

#

yeah still the same problem as before

#

it should not say None-1

tepid island Feb 8, 2025, 3:10 PM

#

should i disconnect my hdmi and reconnect it and see if that does anything?

leaden comet Feb 8, 2025, 3:10 PM

#

i don't know

tepid island Feb 8, 2025, 3:11 PM

#

should i try cvt?

leaden comet Feb 8, 2025, 3:11 PM

#

i guess yea

tepid island Feb 8, 2025, 3:11 PM

#

cvt 1920x1080 144 right?

leaden comet Feb 8, 2025, 3:12 PM

#

if ur screen is 1920x1080 and has 144HZ than yes

tepid island Feb 8, 2025, 3:12 PM

#

ok it said this: # 1920x144 56.64 Hz (CVT) hsync: 9.06 kHz; pclk: 21.75 MHz

leaden comet Feb 8, 2025, 3:13 PM

#

i have an idea

tepid island Feb 8, 2025, 3:13 PM

#

btw just to let u know i have an msi g2712 144hz monitor

leaden comet Feb 8, 2025, 3:14 PM

#

wait

#

have u put an x between 1920 1080

tepid island Feb 8, 2025, 3:15 PM

#

yes

leaden comet Feb 8, 2025, 3:15 PM

#

well

#

try without x (my bad) so cvt 1920 1080 144

tepid island Feb 8, 2025, 3:16 PM

#

says: # 1920x1080 143.88 Hz (CVT) hsync: 169.35 kHz; pclk: 452.50 MHz

leaden comet Feb 8, 2025, 3:16 PM

#

NICE now do xrandr --newmode "1920x1080_144.00" 452.50 1920 2088 2296 2672 1080 1083 1088 1177 -hsync +vsync

tepid island Feb 8, 2025, 3:17 PM

#

ok, didnt do anything just did a new line

leaden comet Feb 8, 2025, 3:18 PM

#

now do xrandr again and see if its HDMI-1 or something around this or it could be for example edp1

sudo apt install nvidia-driver-530 (i dont remember if 530 is the latest version but before when i had this issue it functionned quite well)

tepid island Feb 8, 2025, 3:23 PM

#

why dont i just download the drivers from the driver manager?

#

leaden comet Feb 8, 2025, 3:23 PM

#

oh thx now sudo apt install nvidia-driver-550 is good and driver manager maybe i never tested

tepid island Feb 8, 2025, 3:24 PM

so: sudo apt install nvidia-driver-550

leaden comet Feb 8, 2025, 3:24 PM

#

yes

tepid island Feb 8, 2025, 3:25 PM

#

ok done

leaden comet Feb 8, 2025, 3:26 PM

then u can reboot your machine

tepid island Feb 8, 2025, 3:26 PM

#

oh my days wait i never ran t he cmd "sudo apt update" should i run it quickly

leaden comet Feb 8, 2025, 3:26 PM

#

u can

tepid island Feb 8, 2025, 3:27 PM

#

ok, should i run sudo reboot now?

leaden comet Feb 8, 2025, 3:27 PM

yees

tepid island Feb 8, 2025, 3:29 PM

now what

leaden comet Feb 8, 2025, 3:29 PM

leaden comet Feb 8, 2025, 3:43 PM

#

go on driver manager and make sure that you select the NVIDIA proprietary driver (not Nouveau or open-source).

tepid island Feb 8, 2025, 3:43 PM

#

yeah

#

#

is it looking good or bad

leaden comet Feb 8, 2025, 3:44 PM

#

im sorry but i dont know what to do anymore

#

i tried everything that i possibly could

#

try installing an older version such as 535

tepid island Feb 8, 2025, 3:45 PM

#

what effect would that have?

leaden comet Feb 8, 2025, 3:45 PM

#

ur nvidia card is better in a 535 version

tepid island Feb 8, 2025, 3:46 PM

#

so what should i do to go to 535 version? go to driver manager and select 535 and apply changes?

leaden comet Feb 8, 2025, 3:46 PM

#

i guess so

tepid island Feb 8, 2025, 3:46 PM

#

how can i delete all nvidia packages and reinstall them for 535?

leaden comet Feb 8, 2025, 3:47 PM

#

do sudo apt-get purge nvidia*

loud merlin Feb 8, 2025, 3:47 PM

#

leaden comet do sudo apt-get purge nvidia-*

.

leaden comet Feb 8, 2025, 3:48 PM

#

is there something i did wrong ?

tepid island Feb 8, 2025, 3:48 PM

#

does the - matter?

leaden comet Feb 8, 2025, 3:49 PM

#

in the end of nvidia no

loud merlin Feb 8, 2025, 3:50 PM

#

I would consider not to blacklist nouveau. that could make it so no display is usable at all

#

ie - undo that blacklist

tepid island Feb 8, 2025, 3:51 PM

#

loud merlin ie - undo that blacklist

what is the cmd? im new to linux sorry

leaden comet Feb 8, 2025, 3:51 PM

#

u can delete the file of it im not sure

#

so sudo rm /etc/modprobe.d/blacklist-nouveau.conf
if i am not wrong

loud merlin Feb 8, 2025, 3:52 PM

#

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

#

or remove it as mentioned

#

rm = remove aka delete
nano = a terminal based text editor

leaden comet Feb 8, 2025, 3:54 PM

#

or use kate if u are really unfamilliar with terminal based text editor but u need to install it i think

tepid island Feb 8, 2025, 3:54 PM

#

yeah i changed to the 535 version and nothing changed, what is going on

loud merlin Feb 8, 2025, 3:55 PM

#

xed is included in Mint Cinnamon. so if u need to edit something with root perms, sudo xed

tepid island Feb 8, 2025, 3:55 PM

#

i dont use cinnamon

leaden comet Feb 8, 2025, 3:55 PM

#

whaat ?

loud merlin Feb 8, 2025, 3:55 PM

#

what desktop?

leaden comet Feb 8, 2025, 3:55 PM

#

u seem to have a good pc

tepid island Feb 8, 2025, 3:55 PM

#

xfce

loud merlin Feb 8, 2025, 3:56 PM

#

then replace xed with mousepad

#

eg: sudo mousepad

tepid island Feb 8, 2025, 3:56 PM

#

alr, but how do i get 144hz for my pc then

loud merlin Feb 8, 2025, 3:56 PM

#

but anyway, did u reboot?

tepid island Feb 8, 2025, 3:56 PM

tepid island i remember enabling secure boot because i put a password for it

there's some difficult way to have nvidia support drivers with it on, but no one I know knows it. easier to turn off SB in BIOS

ok i disabled secure boot

#

driver 535 is there now what

loud merlin Feb 8, 2025, 4:05 PM
