Hi,

I am still an unexperianced linux user. But I encountered a problem that seems to be unfixable to me as a user.

My laptop is a tuxedo infinityBook pro gen2 with an intel iris xe integrated gpu in its intel i7 11370h.

At the moment it runs on ubuntu 24.04.

My Problem: My 3440x1440 display gets recognized, but its resolution does not work properly. It looks like the resolution is set to the correct size, but the monitor does not recognises it if this makes any sense. It means everything is to big and parts are invisible because they simply leave the panel.

My searches led me to following: It seams like the support for this resolution was patched into the driver only for 22.04 and 23.04. Since I updated the driver as stated on the intel site and nothing changed, I guess I have three options now:

Reinstalling an older version of ubuntu
Wait for a fix by intel
Downgrade to an older version of ubuntu.

Atm option 3 feels like my way to go since I am not the admin of the laptop. Nor i want to wait.

I found tutorials to downgrading but also comments wich said, it is to avoid to downgrade.

Is anybody in here that has ever downgraded ubuntu or fixed my problem somehow?

Thx for reading.

Are you sure it's not the refresh rate that's the problem? Or some other setting that's incorrect?

How did you apply the patch for 22.04?

Downgrade isn't a supported process. There might be someone who has figured out all the corner cases and created a process for it. Even if that's the case testing would be limited since this isn't a common operation, therefore there are likely to be undiscovered issues with it. You wouldn't know if a problem was caused by that or not. The best way to avoid as many issues as possible is to go with the most tested process - the "happy path." That's backing up your data and installing 22.04 clean or option 1. Option 3 would require admin privileges too so if you can't do option 1, you likely can't do option 3 either.

Well, if I need administration rights to downgrade, I better contact the admin for a fresh reinstall.

Thanks for your answer (^ . ^)/
