I have a rawhide partition that I started that had a 6.12 kernel, upgraded to 6.13. When it upgraded to 6.13rc1 I get a blank screen on my Asus Zenbook UX3404VA_Q410VA. I reboot with the kernel 6.13.0-0.rc0.20241119git… it works. Newer kernels give blank screens. I tried a new rawhide iso and it boots to blank screen. The new iso works on my older lenova just fine. Where do I start to see what is happening?
You could use git bisect on the kernel sources to fi d the commit that break your hardware. That requires you to build your own kernels to test.
