Kubuntu 26.04 briefly freezing every so often

Great detective work, @Plecton.

So, what’s the plan now? Wait for Ubuntu to push the 7.0.12 (or 7.1) kernel or should the mainline one be good? I did se a bluetooth driver segfaulting in my syslog on the mainline (not that I need it, but still). While this is technically a (temporary) solution, I’m gonna leave the thread open for other people that have some findings to report.

You could see if it’s already in the proposed pocket, like this user has done; don’t do the APT pinning, though, it’s obsolete, so just:

sudo tee /etc/apt/sources.list.d/ubuntu-proposed.sources >/dev/null <<'EOF'
Types: deb
URIs: http://archive.ubuntu.com/ubuntu/
Suites: resolute-proposed
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
EOF

then sudo apt install --update linux-image-7.0.0-26-generic (do not just upgrade linux-generic, which will make your kernel track proposed; do it manually) and reboot; the NVIDIA modules should build automatically; or just use the *-open variant which should be precompiled and no DKMS neccessary, IIUC — still not an NVIDIA user.
