Newer kernel and/or X packages from backports are unlikely adequate for needed support. Whether or not you have already tried the guc/huc command line options there I suggest you visit <https://wiki.archlinux.org/title/Intel_graphics> and give all the help there a try. Debian 13 Trixie is well along in development with full version freeze in effect as of last month. A fresh Trixie installation instead of upgrade from Bookworm may be the path you need to take. If this does not work, I suggest you file a bug report. You may consider testing a live media or an installation of a distro that stays more current than Trixie will be when released. All the Alder Lake bugs /should/ be gone by now in the latest of everything, /including Trixie/. Fedora 42 was released in April. openSUSE Tumbleweed gets released as often as 7 days per week. I use both in addition to Trixie and Bookworm. If in such testing the problem remains, surely an upstream bug is involved. Nomodeset is a troubleshooting workaround that never supports two displays. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg.
