[SOLVED] Kwin 5.26 Failing To Start

After upgrading to Kwin 5.26, all of my windows shifted to the top right corner of the monitor and the usual Minimize / Maximize / Close bar disappeared. Upon further inspection, I found that Kwin was not running.

Running

 kwin_x11 --replace 

returns

 kwin_x11: symbol lookup error: /usr/lib/libkwin.so.5: undefined symbol: drmModeFormatModifierBlobIterNext 

I was only able to temporary alleviate this issue by downgrading back to kwin-5.25

I have currently tried the usual 'pacman -Syyu' reinstalling Kwin, deleting kde / kwin profile data, and creating and logging in as a new user, all without any success. I'm not exactly sure what specific additional info to provide, but please let me know if there are any commands to run that might help debug, and I'd be happy to post the results.
Thanks in advance!

Re: [SOLVED] Kwin 5.26 Failing To Start

Welcome to the forums.

Please post pacman.log and the journal (see link below for information about sending it to a pastebin service).

Are you using X or Wayland?

Re: [SOLVED] Kwin 5.26 Failing To Start

With what version of libdrm?

This reeks of a partial update.

Re: [SOLVED] Kwin 5.26 Failing To Start

That's likely because of the way Debian handles libraries. In Arch libkwin.so.5 is linked to libdrm.so.2, which includes that symbol.

Re: [SOLVED] Kwin 5.26 Failing To Start

I was actually up-to-date with libdrm-2.4.114-1, however this comment gave me enough of a clue to solve it.
Attempting to update libdrm gave me an error saying that it was conflicting with libdrm-git, which I didn't actually have installed. However, installing libdrm-git via the AUR allowed KWin to update successfully.

I feel like having libdrm and libdrm-git both installed isn't best practice, but... it seems to be functioning?

Re: [SOLVED] Kwin 5.26 Failing To Start

There's no way to have both installed, they conflict both from the package and from the files. What does pacman -Qi libdrm show?

The confusing part was that I didn't see libdrm-git in my AUR builds folder before this install, and I'd like to think I wasn't stupid enough to delete it in the past out of some sense of 'Ehh, this doesn't look important,' but... you never know.

Re: [SOLVED] Kwin 5.26 Failing To Start

So yeah, you *only* have libdrm-git installed. From the error you got, that's also what you had installed before and why you had the problem. Installing the normal libdrm package would work fine and would have avoided this.

What does pacman.log have to say?

Re: [SOLVED] Kwin 5.26 Failing To Start

Makes sense. Is there an easy way to switch, or am I in too deep to the AUR version at this point? I obviously can't do a simple 'Uninstall libdrm-git, Install libdrm' because all the 'Required By' packages freak out, but maybe there's a command / option to tell pacman it's a switch and temporarily ignore it?

Re: [SOLVED] Kwin 5.26 Failing To Start

I'm guessing lib32-libdrm-git specifically requires libdrm-git. All you have to do is install libdrm and lib32-libdrm, it should prompt you to remove the -git versions.

Re: [SOLVED] Kwin 5.26 Failing To Start

That's not the relevant part of the log, but it does confirm that you had ibdrm-git 2.4.102.r12.g77687f8d-1, which is much too old.

Got it in one. Really appreciate the help.
