The problem goes away when using the "nomodeset" option in the kernel. Hardware: Dell Precision 7530 laptop, Radeon Pro WX 4150 and integrated GPU Intel UHD Graphics 630. I have tried this with fedora kernels (the distro I use), and also with an OpenSUSE live USB with a kernel 5.8.10. The problem persists, and the "fix" is the same. I attach the kernel log of a boot with the 5.8.11 kernel. Extra information: I have had some problems with suspend, after suspending the screen is blank and I have to close the lid and open again. This happens since various kernels ago, but I never reported because it wasn't serious and I use hibernate anyway. It may be related, since it works after suspend-wake up. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
