Won't wake up after suspend!

Hello,

I installed ArchLinux with XFCE4 on SSD.
Installed Nvidia driver, it works perfectly.
Everything is updated and latest softwares installed.

When I suspend the system it does not wake up, the system powers On but,
keyboard does not work (can not get numlock On or Off) and display does not power On too
just a black screen ...

another question ...
I have DVB Qbox 5890 USB, is there any chance to run my DVB under Arch? Is there any DVB player like DVBDream?

Thank you very much.

Re: Won't wake up after suspend!

It's better if you separate the questions in two different threads with a specific subject. I cannot answer the first question. For the second question:

It's possible to watch DVB under linux if the kernel support your card. Sometimes you have to install a special firmware yourself (see dmesg after plugging the card). Once the card is recognised, use w_scan from the AUR to generate a list of channels and frequencies. This tools can generate playlists for various players. Then use one of the supported players like vlc (easy to use once you have the playlist) with the generated playlist. For more infos see: https://wiki.archlinux.org/index.php/DVB-T.

Note: Unfortunately you cannot usually scan the channels directly from the player, using an external tool like w_scan is necessary. Some tools use a country specific list of pregenerated channels to scan. Avoid these tools and use w_scan that is just able to scan every possible frequencies (that may takes a little longer but it is acceptable and more reliable).

Re: Won't wake up after suspend!

From my personal experience, those two questions might actually be related. At least the dvb_usb_dvbsky *used* to nuke the usb stack across S3 cycles, so I use

/usr/lib/systemd/system-sleep/dvb_usb_dvbsky.sh

#!/bin/sh
case $1/$2 in
	pre/*)
	modprobe -r dvb_usb_dvbsky
	;;
	post/*)
	modprobe dvb_usb_dvbsky
	;;
esac

but there're actually maaaany things that can cause this (inc. acpi, watchdogs and the nvidia blob has a record on this as well)

See whether the system at least still responds to pings (the turned off display may just be DPMS) - maybe you can even ssh into it?
Otherwise provide the output of lsmod and lspci and the other HW specs, but prepare for poking around to find the problematic device.
