Hi, I have just upgraded to Debian 12 and find Lyx will not load. In addition, trying to load it seems to crash xorg, so the only way out is to reboot. I was going to post the slew of error messages from the terminal, but as soon as I opened Claws the display became unusable. Moving the cursor led to a broad black line across the display, and clicking no longer worked.
I have tried starting Lyx from the terminal as a different user, and I get this: [different user]:~$ lyx 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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb. I have checked, and xcb is installed. Any suggestions? Should I try to revert to an earlier version, which worked just fine under Debian 11, and if so how would one do that? I have tried reinstalling as suggested above, but it makes no difference. What happens on launch is that a large window with no borders comes up. The Lyx starting logo is in the middle. But there is no toolbar, neither right nor left clicks work either. This is Debian 12 with fluxbox. Any help gratefully received. I can try running debug if anyone knows what flags to use and what to look for. Peter -- lyx-users mailing list lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users
