Christopher, why is this supposed to be a "graphics driver issue" that would need to be split up into isolated bugs per GPU and per system (so that none shows the "big picture" and aggregate Bug Heat of likely Mode Setting or similar hardware re-initialization troubles on resume) ?
With the references of the original report https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-331/+bug/1341270/comments/0 to possibly related bugs edited out, individualized instances may be made appear as of Low importance and remain Unassigned for long (to what end though?), but freeze-on-resume means a serious total loss of all unsaved data, potential file system corruption and severe risk recurrent from earlier LTS releases where the circumstances triggering it and their "solution" (some kernels simply unaffected) never seem to have been fully understood either. Guidance as to what contributions may be provided for the purpose of debugging is much appreciated. Per Wahlström at https://bugs.launchpad.net/ubuntu/+source/pm- utils/+bug/999638 #18 et seq. had already made every conceivable effort more than 2 years ago but there still seems to be no indication who picked up how from there. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1341270 Title: [HP Compaq dc7800 Convertible Minitower PC] 14.04 freezes on suspend resume with nvidia-331 Status in “nvidia-graphics-drivers-331” package in Ubuntu: New Bug description: Sometimes the screen shows a blinking text console mode prompt and the NumLock key can still turn its LED on and off for a few seconds under nivida-331 before the machine freezes with fans running after resume, while nouveau would even permit Ctrl-Alt-F1 occasionally (but then has other log-flooding issues as indicated at the prior link).
