BTW: both Kubuntu 25.04 and 25.10 do run X11/Xorg during login screen, start wayland just for user session.

After updating to Kubuntu 25.10 (do-release-update -d) the screen resolution is fixed to 800x600, and can't be changed in the kde settings. Seems as if the driver is gone and notebook now runs in standard VGA mode. btw., I do need kernel option nomodeset, otherwise screen remains black after booting (both in 25.04 and 25.10) regards ProblemType: Bug DistroRelease: Ubuntu 25.10 Package: kwin-wayland 4:6.4.5-0ubuntu3 ProcVersionSignature: Ubuntu 6.17.0-5.5-generic 6.17.0-rc7 Uname: Linux 6.17.0-5-generic x86_64 ApportVersion: 2.33.1-0ubuntu3 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: KDE Date: Sat Oct 11 00:42:58 2025 InstallationDate: Installed on 2025-04-24 (169 days ago) InstallationMedia: Kubuntu 25.04 "Plucky Puffin" - Release amd64 (20250417) SourcePackage: kwin UpgradeStatus: Upgraded to questing on 2025-10-10 (0 days ago) --- ProblemType: Bug ApportVersion: 2.33.1-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: hadmut 2308 F.... wireplumber /dev/snd/seq: hadmut 2298 F.... pipewire CasperMD5CheckResult: unknown CurrentDesktop: KDE DistroRelease: Ubuntu 25.10 InstallationDate: Installed on 2025-04-24 (169 days ago) InstallationMedia: Kubuntu 25.04 "Plucky Puffin" - Release amd64 (20250417) IwDevWlp1s0Link: Not connected.
