[cepelinas9000]

curious @artist4xlibre this xrandr command for testing? or there are special use case for overlapping output.

[artist4xlibre]

There's no overlap; it places the larger display at the right hand side of the smaller one.
This command used to work perfectly with XLibre, but not any longer unfortunately.

[cepelinas9000]

This command used to work perfectly with XLibre

It was working 25.0.x branch? and stoped from 25.1.x first version?

[artist4xlibre]

It was working on all Xorg and XLibre releases, including 25.1.3, but no longer from git build.

could you please try to git-bisect it, so we know which commit exactly broke it ?
thx.

• sometimes you need to remove build directory and try again compilation (start build directory from clean state)
• on non compiling commits you can use git bisect skip
• or on lucky cases fix them. (this error - you can delete duplicate declaration)

[artist4xlibre]

I only build in clean chroots.

The error is:

../xserver/hw/xfree86/common/xf86_pci_priv.h:22:19: error: static declaration of
‘pci_device_is_boot_display’ follows non-static declaration
   22 | static inline int pci_device_is_boot_display(struct pci_device *dev)

What should be removed exactly? Can you pls provide a git diff for this? Then I'll add it as a patch to the build.

[artist4xlibre]

f5295b8 builds and works fine now; I'll continue bisecting

[artist4xlibre]

This is the problematic commit: e2550d0 "randr: do full transform when checking SetScreenSize size"

Probably L281/L282
