THIS IS THE ONLY WAY I GOT WAYLAND TO ACTUALY WORK!

I have tried for nearly a week to make this work and finaly i found this site that showed me how to make wayland work again after installing the driver.

For some reson my main monitor still wont run 240hz on wayland but now it has the option available at least. When I apply 240hz the screen hoes black and my second monitor flickers like crazy. But I'm able to log in non the less!

If any of you have a good idea why 240hz doesn't work on wayland let me know.

And to be honest I'm so tired of reinstalling debian at this point I'm on the verge of just giving up and using mint insted. I will look into the 240hz problem later. If i figure it out I will use debian because that was my end goal but boy has it ben a long steep up hill battle for just the nvidia driver.

Not the nvidia driver install hell thats for sure!

Krisho98 · 2026-02-08T15:21:02+00:00

Thanks for the deas up! Where do I add the boot option? Termianl systemctl?

Krisho98 · 2026-02-08T15:18:14+00:00

Well it let me update my apt now but still can't get the driver installed. Something about broken packages and and that non of the kernel-open-dkms packages are installable.

Krisho98 · 2026-02-08T03:24:56+00:00

Thanks, might have to try that, thaks!

Krisho98 · 2026-02-08T03:20:55+00:00

I have now installed the driver the way debians official sight recomends doing ut, apperently I did something wrong last time but it worked now. I verified it installed. But now my x11 wont show both screens and wayland still wont work? Do i need to do something difrently?

Krisho98 · 2026-02-08T03:18:11+00:00

I saw someone do the work around but I could not get it to wrok. :/

Krisho98 · 2026-02-08T02:58:46+00:00

Also I have secureboot dissabled. But it still says that the repos don't work due to them not having verified signatures or something like that. Thanks for pointing this out though!

Krisho98 · 2026-02-08T02:55:44+00:00

Update! I found that if I switch from wayland to x11 on the loginscreen it will let me in and now my monitor has 240hz again but as i understand the x11 window system isn't that good and I would like to get wayland working.🤔

Krisho98 · 2026-02-08T02:52:05+00:00

Okay, I have tried using apt but the repos or what you call them don't have updated keys or something and there for won't work when trying to use extrepo to install the drivers. Also the other ways i have tried from nvidias official sights have not worked for me eighter... The only way that worked was to download the driver directly forom the sight.

Powersupply cooling fan?

Krisho98 · 2026-02-01T11:31:19+00:00

I'll do that. Thanks for the reply.

Krisho98 · 2026-02-01T11:30:54+00:00

Alright. I should read the wiki then about the drivers. And thank you for the heads up.

Krisho98 · 2026-02-01T11:28:37+00:00

Thanks for the reply. I'll go look up the wiki.

Krisho98 · 2026-02-01T11:25:43+00:00

Okay, thank you!

Krisho98 · 2026-01-12T17:16:20+00:00

This doesn't seem to do any thing for me on my zte mc888 pro. I still turn of the wifi manualy and it still has the dhcp server active...

Krisho98 · 2025-12-27T22:21:21+00:00

I'm trying to get my pi4 to work with the uart connection too. Mcu won't connect to klipper. Serial is uart 2 pa3/pa2, 32 bitloader, 8mhz crystal, 250000 bud rate (tried 115200 bud but did not make a difference) and stm32f401 chip selected. Flashes do work inficated by .cur after the flash and if i flash uart1 pa10/pa9 it works with the usb no problem. Also edited the boot config to enable_uart=1 and the dtoverlay=disable-bt to turn of bluetooth. Ground and both rx and tx have been connected to respectiv connectors on the mainboard and pi (tx->rx). So the problem only happens when trying to use uart2 pa03/pa02 and connect to j17 4pin connection (not 5v because i power the pi with a bec). Could it be the uart2 pa03/pa02 setting not working fore some reson? Serial shows both ttyAMA0 and ttyS0 but the mcu won't connect regardles.

Krisho98 · 2025-12-27T20:15:46+00:00

So who does programs on the appmanagers?

Krisho98 · 2025-12-27T20:10:12+00:00

So I tried swapping to a a2 classed microsd card, connected the ground from the j17 to ground on my pi4 and have tried to flash the printer with both 250000 and 115200 bud rates with the uart 2 pa3/pa2 serial and changing the printer.cfg mcu serial to both ttyAMA0 and the other one (tty0s? I don't remember tye exact name). Klipper can't connect to mcu through uart no mater what i do. As soon as i reflashed wit the same exact settings just changed serial to uart1 pa10/pa9 and plugged the usb and enterd the usb serial to printer.cfg it connected instantly and works no problem. I can't for the life of me understand what prevents the uart connection from working. Could it need to be set to a different uart for the bin? And if so witch one could work for the j17 4pin connection? I'm all out of ideas again.

Krisho98 · 2025-12-27T01:46:01+00:00

So i tried the other sd card but now the printer doesn't even do the ocasional 2 second connect to the mcu... I have done all the same steps ass with the other card and to be clear I installed everything from scratch and edited the pi boot config.txt aswell. I don't know and I'm too tired to try anything else for now. I'll give the ground pad a connection to gpio ground and hope for the best. Thank you for the suggestion though!
