> Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Not as far as I know. Suspend/resume never worked on this platform. I tried several years ago and it did not work then, either. > Would it be possible for you to test the latest upstream kernel? Not easily I'm afraid, as I'd have to switch to the nouveau graphics driver, and as mentioned in Bug#1639180 Comment #65, on this platform nouveau crashes too often to be useful. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1683165 Title: suspend/resume yields blank screen on NVIDIA desktop Status in linux package in Ubuntu: Incomplete Bug description: On my desktop when I set "System settings > Power > Suspend when inactive for" to any time (5 minutes, say), and wait, Ubuntu suspends. When I power my desktop back on, it boots without the usual chatter on the screen and the screen stays entirely blank (the monitor is in power-save mode). At that point the only workaround is to force a reboot by holding down the power button for 4 seconds, and go through the ordinary boot process. This appears to be the same symptoms as Bug#1283938, the last comment of which says "file a bug by running 'ubuntu-bug linux'", which is what I've done here. I have had the problem for years but have not reported it until today. My desktop has an Asus M4N78 Pro motherboard, which uses an NVIDIA GeForce 8300 chipset. lspci reports the graphics controller as "NVIDIA Corporation C77 [GeForce 8300] (rev a2)". "Software & Updates" says I am using "NVIDIA legacy binary driver - version 304.135 from nvidia-304 (proprietary)". As discussed in Bug#1639180 comment#65, I cannot use the latest NVIDIA driver as it has so many artifacts on the screen that it is unusable.
