Follow-up: the board is now running headless, with gdm.service masked and multi-user.target as the default boot target. GDM was stopped at 2026-10-30 05:12 UTC.
At the follow-up check on 2026-10-31 at 03:20 UTC, uptime was 22 hours 16 minutes. Available RAM was about 13.5 GiB, and the sysstat samples showed no continuing downward trend. The readings were: MemAvailable: 14183448 KiB Shmem: 28172 KiB Unevictable: 51472 KiB msm DRM GEM: 10 objects, 25169920 bytes (24 MiB) The roughly 11 GiB shown as buff/cache was reclaimable filesystem cache. Shared and pinned memory stayed low, and the GPU buffer count was back at its small baseline. There were no GNOME Shell Mesa submission errors recorded in this boot. This longer stable run is with GDM disabled. It supports avoiding the leak by running headless. It does not establish that disabling login- screen animations alone fixes the problem during extended graphical use. The animation setting remains in place, but that test is still limited to the short controlled run in the original report. The bug remains unresolved for graphical operation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2172594 Title: VENTUNO Q: idle GDM login screen accumulates pinned msm GPU buffers until memory is exhausted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-qcom/+bug/2172594/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
