Like in the subject.

the system is:

Code:
Linux gentoo2018 4.14.83-gentoo #1 SMP Mon Dec 10 19:37:20 CET 2018 x86_64 Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz GenuineIntel GNU/Linux


No build failure, Lumina build fine and I did try pretty much all the ebuilds available, and the problem is always the same.

This is the actual installed build:

Code:
max@gentoo2018vb ~ $ sudo emerge -av lumina
Password:
Riprovare.
Password:

 * IMPORTANT: 2 news items need reading for repository 'gentoo'.
 * Use eselect news read to view new items.


These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] x11-wm/lumina-1.3.0_p1::gentoo  USE="desktop-utils" 0 KiB

Total: 1 package (1 reinstall), Size of downloads: 0 KiB

Would you like to merge these packages? [Yes/No]


As I said everything build fine with no problem, the load start pretty fine and everything crash in the end of the load, loading some widgets. Also deleting the configuration folder and start from scratch doesn't improve.

Here what exactly happen during the load:

Code:

I have the same error. Rolling back to qt-5.9.6 fixes the problem for me.

Hello, thank you for your reply. Even if I want to do that, and I wont, regression to 5.9.6 is not possibile becouse 5.9.6 is not in the portage anymore.

I'm much more interested in learning what happened and why this late load crash.

I'm much more interested in learning what happened and why this late load crash.

Further investigations show the problem is limited to x86_64, becouse pure X86 seems to work fine on another box.

I understand many people do not use Lumina as a desktop, so even in this usually competent forum, support is limited.

I know it owrks with qt <5.10, then it wont work with qt >5.10, and as I said limited to x86_X64 platform.

I want try to e.mail ebuld mantainer and see if he can do something.

Like this, Lumina ebuild for x86_64 systems is useless and a not working buggy piece of software in Portage.

Piggy,

Have you tried the 9999 ebuild? Maybe upstream has already fixed that problem.

A little update: The -9999 ebuild misses a qtdbus dependency. After manually installing qtdbus the ebuild fails with a sandbox violation.

Don't use/install the theme engine (lthemeengine) in Lumina. I'm working on a fork off Lumina and I don't have this problem (and I don't use the theme engine), works fine in Qt 5.12.
