Hi, I have an older laptop (Dell Latitude D630) that I’m currently using for testing Wayland. I’ve tested Wayfire, Labwc, and Cosmic. Also, I’ve installed LXQt (X11) as 100% working fallback. Recently, there was an LXQt update to 2.0.0, but before updating my main PC, I’ve decided to check it on the laptop first. But even before doing the update, it failed to run from tuigreet:
| Code: | X.Org X Server 1.21.1.13
X Protocol Version 11, Revision 0
Current Operating System: Linux nugget 6.10.5-gentoo #1 SMP_PREEMPT_DYNAMIC Fri Aug 16 08:4636 CEST 2024 x86_64

Current version of pixman: 0.43.4

When trying to run startlxqt:
| Code: | lekto@nugget ~ $ startlxqt
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: minimal, offscreen, wayland-egl, wayland, xcb.
Aborted (core dumped) |
I tried to add vesa to VIDEO_CARDS (in case of broken Intel driver) and rebuild the whole QT stack, but those didn't help. |

I'm not familiar with 'tuigreet', but in any case, the '/home/lekto/.local/share/xorg/Xorg.0.log' while could perhaps offer some hints towards what is breaking (I suspect there might be a segmentation fault of sorts hiding there, but hopefully it is something less severe).

A couple of suggestions:
* Try setting QT_DEBUG_PLUGINS=1 before running tuigreet, to see if that provides any more details.
* Check which XCB packages are installed on your system. E.g. on mine:
| Code: | $ eix -I xcb
[I] x11-base/xcb-proto (1.17.0@05/07/24): X C-language Bindings protocol headers
[I] x11-libs/libxcb (1.17.0(0/1.12)@05/07/24): X C-language Bindings library
[I] x11-libs/xcb-util (0.4.1@06/07/24): X C-language Bindings sample implementations
[I] x11-libs/xcb-util-cursor (0.1.5@06/07/24): X C-language Bindings sample implementations
[I] x11-libs/xcb-util-errors (1.0.1-r1@08/07/24): Library that gives human readable names to XCB error, event, & request codes
[I] x11-libs/xcb-util-image (0.4.1@06/07/24): X C-language Bindings sample implementations
[I] x11-libs/xcb-util-keysyms (0.4.1@05/07/24): X C-language Bindings sample implementations
[I] x11-libs/xcb-util-renderutil (0.3.10@06/07/24): X C-language Bindings sample implementations

I think this usually means you need elogind setup (assuming not on systemd as you'd always have logind then) or xorg-server[suid]. But it's a bit more odd if it broke out of nowhere. |

Nothing interesting in /home/lekto/.local/share/xorg/Xorg.0.log; it loads glx and vesa modules; after that, there is the permission denied.
My eix -I xcb looks similar.
I have no mention of logind or elogind in /etc/portage and emerge --info, so it looks like I didn't touch them. |
