Relevant system info:
Lenovo Ideapad Y500 (SLI and NO Optimus)
2 x GT 650M cards in SLI
Arch Linux 64-bit 3.9.2
Current driver: 319.17 (though I’ve tried it on 310.40 and 319.12 too)
I originally posted this issue in the Arch Linux forums, because I wasn’t sure where the problem was (https://bbs.archlinux.org/viewtopic.php?id=162448). Now, I believe that it’s an Nvidia issue.
Laptop functions normally, except, when I ctrl+alt+fX to a tty, all I get is a solid underscore cursor on a black screen and it never progresses from there. I’m using the efifb framebuffer. I can go back to my KDE session and everything is still fine. The other issue is that it won’t ever resume from sleep (I’ve tried systemd and pm-utils). There doesn’t seem to be any relevant info in the system logs (via journalctl). The laptop seems to start everything back up, including the screen backlight, but nothing is ever displayed – I also checked both external monitor connectors when this happens, in case it was trying to output elsewhere. I was able to ssh into it after resuming, so I know the system was at least mostly running.
The (temporary) solution:
In order to fix both of the issues, I just need to disable SLI in the xorg.conf (eg Option “SLI” “off”) or physically remove the 2nd card.
I’ve attached my journalctl log that includes an instance of not being able to resume (happens at May 19 17:09:13). Please let me know what other information would be useful in getting this resolved. Thanks.
