Red Hat Bugzilla – Bug 608346
Lenovo W510: display doesn't come up after resume
Last modified: 2014-03-31 19:45:34 EDT
Notebook properly suspends, but after resume the display is just blank (dark, doesn't come up). Given that NetworkManager connects to the network and I can ssh onto the machine, I expect everything else is fine.

FYI - hibernate works flawlessly.
Looks like problem with vbetool/video BIOS. Could you provide output of lsmod? Please also try with various video quirks, the list of quirks is available from /usr/lib/pm-utils/bin/pm-action --help

Sorry for the late response.
-dpms-on -> no change
-dpms-suspend -> no change
-radeon-off / s3-bios / s3-mode -> haven't tried (does it apply to nVidia?)
-vbe-post -> half success! External monitor came up, notebook display is still "dead". But better then nothing :)
also tried -vbemode-restore/vbestate-restore/vga-mode3 -> no change.
Does VT switch (ALT + [CTRL] + NUMs) help? Or is the display completely dead?
Completely dead, dead black.
Thanks for info, please provide sosreport and output of lshal.

Booted to runlevel 5, CTRL+ALT+F1, login as root. lshal > $log.
I've XXXX-ed out a couple of the serial numbers. In the unlikely case they are needed and should make a difference please let me know.
