PS/2 should just work™. It plugs straight into the MoBo chipset IRQs (via LAPIC these days) and does not rely on userspace applications. > Lots of people seem to have problems with suspend/restart > & it seems to be somewhat random & vary with different makes of mobo, > so any further suggestions here may help others in future too. Yes, I've had my fair share depending on MoBos, especially older builds. I even had laptops with dodgy suspend to RAM performance: it wouldn't suspend at all, or it would and then not wake up properly (screen wouldn't come on again). In my experience suspend to RAM could break from one kernel to another on buggy MoBos, or between different video card kernel drivers (for radeon at least). Note: some modern MoBos have S4 disabled at the BIOS by default, to make sure that USB ports continue to charge mobile phones and tablets. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I specifically remember an older ASUS board that had a jumper by the PS2 port that was defaulted to NOT wake. You had to move that jumper, then go into the BIOS under power options and set wake from keyboard to "space bar" in order for it to work. I haven't had a PS2 keyboard in ages now - I don't think the motherboard on the Intel board I have even has a PS2 port, so I didn't think of the possibility of the PS2 keyboard not working. :-) Dan

Hah - sorry about that. Most people apparently use udev to do that. I
wrote my script first and used it instead. I never really looked into
udev as my script [kludge?] still works, I just tried it.
I posted it in the Docs, Tips & Tricks forum [1] some time back & it's
also on pastebin [2]. Use at your own risk! I've attached it here as
well, hopefully we're allowed to do that on this list. The forum post
lists how to use it.
Wow, 18,000 views to the forum post. I wonder if that's good or bad?
It requires root, so you may want to put it in /sbin/. Run it with no
options and it'll display a usage page. All it does is do some searching
in the /sys/devices tree and tries to find appropriate items to show.

There was a kernel change some time back that disable usb wakeup on all USB hubs. Userspace needs to explicitly enable them or device wakeup will not work. I wrote a script some time back to do that but it can probably be done with a udev rule. Dan

I've done further Google research. Many other people have had similar problems over the past few years & the only regular suggestion is that there's a problem with ECHI etc : I haven't tried following that up, as it's not recent. I tested Mint 17.2 Xfce , which I have installed in another partition & which is very quick'n'slick : suspend has the same effect as with Gentoo. I've tried changing a few BIOS settings with no apparent effect, but -- mysteriously -- Gentoo (but not Mint) is now actually suspending, but doesn't wake up when the power button or a key is pressed, as it should ; I can power off & restart normally afterwards. 'dmesg' + 'syslog' simply show an immediate restart after the suspend. The result of all this is that I can't suspend to RAM & restart later : that merely means that I have to repopulate my workspaces after each reboot, but that's something I know by rote & can easily live with. However, the one good + surprising outcome concerns the I/net. Getting back in touch with my ISP can be slow + unpredictable, tho' it always works after a few tries, which involve powering everything off. However, I've discovered that if I don't switch off the router, 'dhcpcd' simply reconnects after a reboot (in Mint too) & the I/net is immediately available : that's what I really care about. So I can power the machine off while I'm asleep or out iff I don't switch off the power-bar which also feeds the router. If anyone has further thoughts on this subject, they mb of more general interest, but for now I can carry on. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

It's not relevant to the problem, but I don't want to switch off the router which connects to my ISP, as it cb a nuisance to reconnect again.

Am I using the correct tool ? What desktop environment are you using? OpenRC or systemd? Lastly, do you have support for suspending to RAM compiled into the kernel? If you are using a desktop environment, it should have the suspend functionality built into it. If you are using systemd, it should be as simple as a `systemctl suspend`. Alec
[gentoo-user] pm-suspend problem
I want to be able to suspend my machine to RAM overnight or when I'm out. The pkg to use seems to be Pm-utils, which I've installed. 'pm-suspend' does suspend, but only briefly : after 5 s , it restarts automatically & everything is back as before. The log file shows this happening quite clearly. What am I doing wrong ? Am I using the correct tool ? -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca
