I am currently facing the following problem: My laptop works perfectly fine with the lts kernel (6.1.68). But when I try to use the current kernel (6.6.7), my internal display shows the boot process. When this is finished, it shows a mouse cursor for a split second before the screen goes black. Also, trying to display the command line (crtl + alt + f2) does not display anything. When I plug in an external display, it is normally picked up as a secondary display. I can also see and rearrange both displays in the KDE window manager. I have tried different resolutions without success.
See below for more information about my system. I would appreciate any assistance with this problem.
There seems to be a connection. Although the user in the given post describes the screen going black immediately after selection of the kernel, while I can still see the boot process. The screen only goes black when the desktop environment is loaded (KDE in my case). The “solution” in the linked thread is to reinstall EOS. I don’t think this is a real solution. I have had other problems with the non-LTS kernel in the past (e.g. keyboard not working). These were fixed by updating the kernel. So I will wait for a possible upstream solution.
Though if other experience similar issues or have suggestions for a possible fix please let me know
Sorry here are the logs:
journalctl -k -b -1 | eos-sendlog ( I used -1 as I have no display output when the error occurs and I need to reboot with the lts kernel): https://0x0.st/HgPY.txt
So I did not open any bug. And just waited over the Christmas days. Today I just did an eos-update --yay and rebooted my Laptop. No problems since than on both kernels.
